• How to compare speed of graphics cards in Windows desktop environment?

  - by Al Kepp

  I use Windows 7 and Intel Core i3 CPU with integrated graphics. My problem is that it eats valuable system RAM for display. I can replace it with an old PCIe Radeon X700, so all system RAM will be usable for applications. The question is if an old Radeon X700 is comparable in W7 desktop speed to a new integrated i3 graphics. Are there any test programs which compare the speed of graphic cards in Windows 7 desktop environment (i.e. no Direct3D games, just Windows desktop)? (According to Tomshardware, Radeon X700 is probably even faster than Core i3 in 3D. But there are no native WDDM 1.1 W7 drivers for X700, only WDDM 1.0 Vista drivers are available.)

• Windows 7 Slowness following Virtual PC and Visual Studio Install

  - by Elliot Hughes

  I'm running Windows 7 32bit on a 3.2ghz Pentium D with 2gb RAM and a 1TB SATA hard drive. My system was running as fast as it ever has until I installed Visual Studio and Virtual PC a few days ago. Ever since - regardless of whether either application has been running the system has been running incredibly slowly. For example flash video plays jumpily, 3D games that used to run fine are now unplayable and even the smallest amount of multitasking makes the system unusable. I'm confident there is no virus or other such things present following scans in safemode and I'm fairly confident I've made no other changes to my system. Any ideas - I've run out of things to try!

• MS Securily Essentials efficiency / usage, suspicious processes

  - by biggvsdiccvs

  I recently noticed that my (originally pretty fast) Windows 7 Pro laptop started getting slow and using a lot of CPU power for no apparent reason. A full scan by Microsoft Security Essentials revealed nothing. After some investigation, I found multiple instances of a strange process called urpev.exe and a couple of similar exe files sitting in subdirectories of Users//AppData/Roaming (this particular one was in a folder called Xyceowme). Description: "Mescrosift Visaal Studie 2010". Company name: "Mesrosift Corporatien". Is it a virus or something? :) Now, all of these exe files were scheduled to be started from the Task Scheduler by tasks with names like "Security Center Update - 1291373911" and similar. My user name was listed as the author of the tasks. I disabled the tasks, restarted the computer in safe mode and moved all of the exe files to quarantine for further investigation. All of this was done last night. I just scanned the files with Security Essentials again (not updated since yesterday) in the quarantine location and this time it found PWS:Win32/Zbot.gen!plock in urpev.exe (but not in the other exe files, which are most likely viruses, too). Category: Password Stealer Description: This program is dangerous and captures user passwords. Another strange process is browser.exe (not chrome.exe) by Google Inc., described as Google Chrome. I uninstalled Chrome but it's still there. It runs out of Users\\AppData\LocalLow\UIVoice\ToolMedium\browser.exe and if I move it in safe mode, it just reappears there, and multiple instances run. Needless to say, it I kill it, it just runs again. Couldn't see anything in Task Scheduler, but found a couple of references to it in the Registry Editor: HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/LowRegistry/Audio/PolicyConfig/PropertyStore/ HKEY_USERS/S-1-5-21-1685709306-872053864-2599010960-1002/Software/Microsoft/Internet Explorer/LowRegistry/Audio/PolicyConfig/PropertyStore/ Maybe it's a legit process, but seems kind of strange. For the time being, I suspended the process and killed all of the child processes when I booted up the laptop. I used Security Essentials to scan the system periodically, but obviously it's not effective at least against one virus. I had the "real-time protection" turned off. Would it help if it were turned on and how much of a nuisance would it be? I wonder if there is a better alternative to Security Essentials. Over the years I've used multiple antivirus products at home and especially at work and was not very happy with any of them. Apparently, asking for software recommendations or comparisons is taboo here, but I will mention that I installed Malware Bytes and it was able to find an quarantine a bunch of suspicious files, and at least some of which were truly infected, but when it scans the bogus security center update executables from Mesrosift Corporatien, it finds nothing wrong. Also, any thoughts on the browser.exe mystery? Neither MS Security Essentials nor Malware Bytes found anything wrong with that file. However, after I ran a Malware Bytes scan and quarantined everything it found suspicious and rebooted the laptop, the process did not run.

• Wii game bought in US, will it work on a PAL console in Europe?

  - by Stijn Sanders

  I can't seem to find a European online outlet that offers this Wii game I'm looking for. If I would buy it from a web-shop in the US, could I end up with a game that doesn't work well with my console? I'm worried because all games I have for the Wii so far have a prominent mention of "PAL" on the cover. I didn't notice "NTSC" on the photo's of the cover online, but I'm worried none the less. (And thought I'd ask it here first...) Also, does anyone happen to know if Belgian customs would add tax to shipments like this coming in from the US?

• Keep only "lock" a single app open in iOS?

  - by CT.

  Is there anyway to "lock" open a single app in iOS? My use case for this is simple. There are many apps and games designed for children. While these applications are appropriate for children, many other applications installed on an iPad are not. But even more so than protecting them from inappropriate content, I would just like to prevent them from leaving the application. They accidentally hit the home button or multi-touch gesture out of the application. I know you can turn gestures off. Developers also have links to their website or other related applications. Kids are constantly exiting the application and then bringing the device to me asking "Can you get me back into the game?" every couple minutes. How can I hand a child an iPad with "Angry Birds" running and make sure only "Angry Birds" runs? Cydia or jailbreak tweaks welcome. Thanks.

• How to add nvidia drivers after previous failure with linux mint?

  - by LessThanMe

  Before today, I had perfectly good drivers from nvidia for my linux mint (15) box. I decided to update it because my performance in TF2 is less than stellar, and then things went south. I used synaptic to install nvidia-331 and then rebooted, but when I selected Mint in GRUB I waited...and waited...and waited. Nothing happened, but the display stayed on (a completely black video was being output). So I went into recovery mode from GRUB, went to root access, and apt-get remove --purge nvidia*'d my way out of that mess, and installed nvidia-common. Now my performance in graphic intensive stuff (read: games, blender) sucks, so I've been through the same thing a few times trying to re-install nvidia-current. I just want to get it back how it was. Thanks for any help! Nvidia GTX 560

• How much processor speed and cores do I need for these tasks?

  - by ajay

  I am planning to buy a new laptop as I find my current one very slow. My question here is specifically related to RAM size and CPU power. I will mostly be doing development (not much games). I would be dabbling in distributed computing, multithreaded and data intensive parallelizable tasks on multi-cores. For e.g. I would want to be able to Concurrent programming in Scala/Java/Clojure etc. and be able to see parallelization. Furthermore, I would want the RAM to be enough. But from a developer machine standpoint, do you think 4GB RAM and 2.53GHz Dual Core processor would be enough. I'm basically looking at this model: http://store.apple.com/us/configure/MC118LL/A?mco=MTM3NDcyODk (link dead)

• Sharp flat panel scaling with Nvidia drivers

  - by Brecht Machiels

  I have a Samsung 226BW flat panel with a 1680x1050 native resolution. As my PC is rather dated (Athlon XP 2600+ and GeForce 6600 GT), I need to run more recent games (but still old) on a lower resolution. Unfortunately, scaling low resolutions to 1680x1050 results in a very blurry image (bilinear scaling). I have created a custom resolution of 840x525 in the Nvidia control panel. Technically, this resolutions allows perfect upscaling to 1680x1050 without the need for bilinear interpolation. Unfortunately, the Nvidia driver always seems to do bilinear scaling, again resulting in a blurry image. However, I seem to remember that I did obtain crisp images using this resolution in the past (before a Windows re-install). Maybe only some driver versions support integer upscaling without bilinear filtering? Or perhaps there are other solutions?

• Use an unsigned driver in Windows 7 x64

  - by rjmunro

  I'm trying to use the RBC9 SpaceNavigator TEST x64 build drivers for my SpaceNavigator 3d joystick so that it can work as a normal joystick in games like Quake. Unfortunately, I get the error "This version of windows requires all drivers to have a valid digital signature" and in the "Device status" in device manager, I get "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)". Is there a way to work around this issue?

• Ping isn't acting accurate?

  - by Earlz

  I've been trying to diagnose some latency issues with my internet connection. I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange. I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average. How does this happen? Is ping still being accurate? I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.

• How does NTFS compression affect performance?

  - by DragonLord

  I've heard that NTFS compression can reduce performance due to extra CPU usage, but I've read reports that it may actually increase performance because of reduced disk reads. How exactly does NTFS compression affect system performance? Notes: I'm running a laptop with a 5400 RPM hard drive, and many of the things I do on it are I/O bound. The processor is a AMD Phenom II with four cores running at 2.0 GHz. The system is defragmented regularly using UltraDefrag. The workload is mixed read-write, with reads occurring somewhat more often than writes. The files to be compressed include personal documents and selected programs, including several (less demanding) games and Visual Studio (which tends to be I/O bound more often than not).

• Best way to backup Xbox 360 USB Drive

  - by TekiusFanatikus

  What is the best way to backup/restore my USB drive that I use for my Xbox? I want to make sure that if the USB drive goes, that I can retrieve my saved games and such onto another USB drive. I was able to show the content of the drive, however, I wasn't sure if I could simply copy the content onto a Truecrypt volume and be able to restore it from there at a later date. The file system is not FAT or NTFS, wasn't sure about the impacts of copying from two different file systems... I currently have a DataTraveler G3 16GB. After a bit of googling, I was able to find this article, mentions an app called USBXtafGUI

• Windows 8.1 unable to play Music or the Audio from videos through Optical Out

  - by Zion Fox

  I am having an issue with my audio output, where any music file, and the audio side of videos are not being played through my optical audio output. I am running a Realtek HD Audio device built on Revision 1.0 on a GA-P55A-UD6 Gigabyte Board, which runs through it's optical output to an Astro A40 Mixamp, which does some upscaling before sending it to the headset. Now, notification sounds, and sounds/videos/music played through the browser or programs like Skype or games are working fine. This seems to specifically effect Foobar2000 and Media Player Classic. I have updated these two programs to their latest revisions, in addition to the soundcard drivers to no avail, and searching the error code thrown by Foobar2000: Unrecoverable playback error: The parameter is incorrect. (0x80070057) through Google returns not very helpful results, other than the one potentially mentioning DRM. This issue I am having a very hard time resolving, and am wondering if anyone here has experienced similar issues after updating.

• How do I get the Dell 3007wfphc monitor to do other resolutions?

  - by Schwern

  I've borrowed a Dell 3007 WFP-HC monitor and it will only do 1280x800 and 2560x1600 resolutions crisply due to its lack of a real scaler. Every other resolution is fuzzy. 1280x800 is pixelated and I doubt my PC can play games at a reasonable frame rate at 2560x1600. Can I get something in between that looks good? I have a GeForce GTX 560 video card and Windows 7. Is it possible to get the GPU to render at a more reasonable resolution, say 1920x1200, and stretch it to the native 2560x1600 to make the monitor happy? I've been poking at the NVIDIA Control Panel but to no effect. Thank you.

• OS specific network delay, why?

  - by Atilla Filiz

  Since my new ISP installed their own router to my house(I rented a room in a student house so don't have much control on these), I started having strange delays. Any outgoing connection I do, be it http or ssh, is delayed for several seconds, and once it is established, I have no further problems. I open several simultaneous tabs in my browser and after about 5 to 8 seconds, they all connect and load simultaneously and quiet fast. I can actually play online games once I connect.What's more interesting is, I experience this only with Linux distros, namely Arch and some versions of Ubuntu. Access with Windows installs are quiet normal. What might be wrong with my router? Everything was fine with my old router but I have to use this one now.

• What's the downsides of Running Ubuntu 9.10 32bit on AMD64 Processor

  - by Omar Dolaimy

  Hi, I was thinking about installing Ubuntu 9.10 32bit on a DELL Inspiron 1501 with 64bit processor Laptop. Since It's was real pain to me to run Java Browser plugin, Flash Plugin, J2ME Toolkit, and many other tools. But It was 90% OK with me. This was Ubuntu 8.10 (a year ago), And now the Ubuntu 9.10 came and I'm thinking about installing the 32 bit on it and get rid of the pain. Is there a downside for that?? considering that the display card is not supported now so exclude this from your calculation, I will never play REAL games on it and I'm not a big fan of Compiz effects. I'm not here to ask about the performance (which is about 15%+ for the 64bit only), I just want compatibility!

• dell u2410 3dMark Benchmark distortion problems

  - by Scanningcrew

  Ive been doing burn in testing for a new system I have put together and I am running into some video distortion problems with running the 3DMark benchmark tools (Both 06 and Vantage). The graphics will be fine, then sometimes during a test switch the screen will light up with thin horizontal ranibow lines (Something that looks very "glitchy") If i turn the monitor off and back on it clears up. All the tests "pass" and my system gets good marks but it concerns me if I might have problems with games (The screen returns to normal if I dont resest monitor and just let tests pass). I want to return a problem component now before its too late if it is something with the new hardware. Also, I am monitoring temp with thermal laser gun and the card itself is not going above 65c. Any ideas?

• Getting jerky backgrounds on Win7 on iMac 27'' 2560x1440

  - by JohnIdol

  I installed Win7 on bootcamp on my new iMac 27'' (ATI videocard) and everything was good until recently I noticed that the default win7 background (then one on the background on login) looked jerky. When I say jerky I mean the kind of jerky you get if you can't display enough colours, and instead of nice fading shades you just get stripes and jerky patterns. I am on native resolution but even if I go down to 1920x1080 I get the same. This might have happened after a firmware update but as I don't use windows very often I am not too sure it's what caused it. Oh, and when I am playing games everything looks OK (as in not jerky!). Any help appreciated!

• Dual boot new laptop win 7 / ubuntu 12.04 - 750gb + 32gb SSD

  - by Alex Waters

  I have just purchased a new HP dv7t-7000 and I would like to run Windows 7 / Ubuntu. How do I setup the dual boot? Can I install both operating systems with an 8gb USB drive? Can I still make use of the 32gb SSD? I'm unfamiliar with the efficacy of using an SSD for caching with a 750gb 7200rpm sata 3 drive. I can only see using it for windows 7 - which I have installed in order to play games. Thank you!

• Is it possible to make the Numpad 5 button work as the Numpad Down button while Num Lock is on?

  - by Eddy

  I hope someone can help me out with this; I use a laptop and I like to play games a lot that are arrow key dependent. So after a while of using my laptop, I accidentally broke the Down Arrow key. So I decided to try and find out how to make the Numpad5 button work as the Numpad Down button while Numlock is on. I was trying to use AutoHotkey, but so far I've had no luck. Can anyone help me out with this? So far the scripts I used that didn't work were Numpad5::NumpadDown or Numpad5::Down. Am I doing something wrong here?

• Jerky animation on window open/close

  - by Jan Zich

  Today, I received and installed Windows 7, and one of the first (slightly) annoying things I noticed is a visible jerk when opening of closing new windows. When I minimize or maximize already running window, the animation is smooth from beginning to end, but when I start a new program, it seems that just at the end of the animation Windows thinks for a fraction of a second. It is a bit distracting; especially since Windows 7 seems to be overall more responsive than Windows Vista. Does anybody has the same experience? Could it, for instance, a 64bit version specific issue (just in case)? I upgraded Vidia drivers, and even though my video card is not capable running latest games, it should be able to handle this (since it was OK in Vista, and since it does not look like a video issue).

• Is opening ports in the firewall bad?

  - by Steven

  From what little I know about networking, opening ports lets external data get sent in. But how that data is handled is entirely up to the applications running on my machine. So if I'm not running any malicious applications, there should be nothing wrong with disabling the firewall, right? Also, how do applications work when ports aren't forwarded? For example, I need to forward port TCP 6112 to host Blizzard games, but I've heard that HTTP uses port 80, but I haven't forwarded that port, yet Firefox still works. Btw I'm using Windows Vista.

• How to set CPU affinity in Wine or CrossOver?

  - by penyuan

  There are some old games who don't like the multicore processors in today's computers. I am wondering if there is a way to set the CPU affinity for them to '1' under Wine or CrossOver? i.e. In a native Windows environment you would right click on the game's process in the Task Manager then set the affinity there. I've came across a program called RunFirst.exe, but can't figure out a way to run it, then the game in one command. Suggestions are appreciated. Thanks!

• Computer becomes very slow (permanently) after running a bunch of apps

  - by djzmo

  Hello there, My computer with Windows XP installed becomes very slow after I ran some heavy tasks at a time. (play a full 3D online game while extracting a 4GB RAR archive) It freezes for about 200~500ms every few seconds, and this always happens if I do heavy tasks at once in my computer (for example, installing a program while playing games), and the lag remains permanently (even a reboot won't make it better) unless I repair-install the Windows. Since I have a low-end computer: Intel(R) Pentium(R) 4 CPU 2.00 GHz, 512 MB of RAM ATI RADEON 9550 AGP 256 MB And the only way I used everytime to fix this problem is by repair-installing my Windows XP. So that I won't lose any data or installed programs. But I believe there's a better and faster way to fix this without repair-installing the Windows. Any idea?
