  • Determining speed (class) of USB on PC

    - by Thomas Matthews
    Is there a method for determining the speed of a USB port on a Windows XP PC, without using a USB protocol analyzer? I'm looking for something simple, such as looking at the Device Manager. I would like to hook up some USB equipment to a USB 2.0 port, rather than the slower USB 1.0 or 1.1.

  • Impressions of my ASUS eee slate EP121 - Dual core 4GB, 64GB SSD

    - by tonyrogerson
    This thing is lovely, very nice bluetooth keyboard that has nice feedback on the keypress, there is no mouse but you can use the stylus or get yourself a bluetooth mouse, me, I've opted for a Microsoft ARC mouse which is a delight to use, the USB doors are a pain to open for the first time if like me you don't have any finger nails. It came as a suprise that the slate shows four processors, Dual Core with multi-threading, I didn't really look at the processor I was more interested in the amount of memory and the SSD; you don't get the full 4GB even with the 64 bit version of Windows 7 installed (which I immediately upgraded to Ultimate through my MSDN subscription). The box is extremely responsive - extremely, it loads Winword in literally a second. I've got office 2010 and onenote 2010 on there now; one problem is that on applying all (43) windows updates since the upgrade the machine is still sat on step 3 of 3 on the start up configuring updates screen after about an hour, you can't turn this machine off without using a paper clip to reset it and as I have just found you need a paper clip :). Installing Windows 7 SP1 was effortless. One of the first things I did on it was to reduce the size of the font, by default its set at 125%, my eye sight is ok :) so I've set that back down. Amazon Kindle for the PC works really well, plenty of text on the screen when viewed portrait, the case it comes with also allows the slate to stand up in various positions - portrait, horizontal - seems stable enough. The wireless works well, seems to have a better signal than my other two laptop machines which is good news. The gadget passed the pose test at work :). I use offline files to keep a copy of all my work stuff locally, I'm not sure what it is, well, its probably my server but whenever I try and sync it runs for a couple of minutes then fails with network name no longer contactable, funnily enough its fine from my big laptop so I can only guess this may be a driver type issue on the EP121 itself - very odd and very annoying. I do a lot of presenting and need to plug into a VGA project because most sites that's all that is offered, the EP121 has a mini-hdmi output which is great except for this scenario, hdmi is digital, vga is analogue, you will struggle to find a cost effective solution, I found HDFury and also a device HP do, however, a better solution appears to be getting a USB graphics adapter for instance the one I've ordered is the ClimaxDigital USB 2.0 to DVI,VGA or HDMI Adaptor which gives everything I need - VGA and DVI output and great resolution as well - ok, so fingers crossed because I'm presenting next Wednesday in Edinburgh and not taking my 300kg lenovo w700 (I'm sure my back just sighed in relief) - it certainly works really well on my LED TV, the install was simple - it just works! One of the several reasons for buying this piece of kit was to use it on my LED TV to remote into my main machine to check stuff whilst sat in my living room, also to watch webcasts and lecture videos in comfort away from my office, because of the wireless speed and limitation I'm opting for a USB network adapter from Belkin - that will also allow me to take advantage of my home gigabit network, there are only 2 usb ports on the slate so I'm going to knock up a hub so connecting it in is straight forward and simple, I'm also going to purchase a second power supply so I don't have to faff about with that either.I now have the developer x64 edition of SQL Server 2008 R2, yes everything :) - about 16GB left to play with on the machine now but that will be fine, I'll put AdventureWorks on there so I can play and demo stuff which is all I'm after from this, my development machine is significantly more powerful and meets my storage needs too.Travel test this weekend and next week, I'm in Dundee for my final exam for the masters degree.

  • Virtual PC: Cannot restore machine from hibernate

    - by Paul Lammertsma
    I have two virtual machines set up from Virtual PC on Windows 7 Professional: Windows XP Mode and Xubuntu. Last time I used them (last month or so), I had closed them by hibernating. Evidently, I have meanwhile downloaded a Windows Update affecting VPC and now receive the following error in restoring either of them from hibernation: 'Xubuntu' could not be restored because of either host processor type mismatch or lack of hardware-assisted virtualization support in the system. I've been through the virtual machine's settings, and there's nowhere an option to simply reboot it. (Virtualization is not the problem, as I can create a new virtual machine without any problems.) Any ideas?

  • Switching from Windows Virtual PC to VirtualBox without formatting

    - by djechelon
    I have a Win7 virtual machine running on Windows Virtual PC where I'm currently developing. I found that I dislike WVPC, and installed VirtualBox, hoping for better performance. However, importing the existing VHD into a new VM seems to not work, because even if I see the Windows boot screen, the OS will crash on a BSOD and requires the restore tool to run. That tool finds no problem, reboots but the BSOD is still present. I wouldn't like to format a new VM if possible. Is it possible to do such switching?

  • Using curly braces with a standard pc keyboard on a mac laptop

    - by raoulsson
    I have a standard PC keyboard connection to my Mac laptop. All keys work fine but the special characters that need "Alt-Gr" as accelerator keys would not work. I have a Swiss layout where the curly braces are such special keys. However I need them all the time and having to get used to a different layout is too painful (I'd rather get used to a US Layout once and for all). Does anyone have an idea how to switch this? Note: I have managed to switch the option and the command key, so that's not my problem.

  • what can I do with an old but working PC [closed]

    - by fskreuz
    I have an old Dell optiplex GX240 on Pentium 4 1.8Ghz and 256MB Ram (or was it 512MB). It's still in working condition but it's getting slow for me and i wanted to optimize it. I just want that old box to be usable even for simple desktop use (email, surfing, chat). I also have to note that my parents prefer use it over a laptop for some reason. Treat it as a "box-type netbook". unlike the other threads that they all prefer sending away or use as file server, firewall and that, i am looking for suggestions on how to keep it usable as the main PC. any suggestions? OS perhaps?

  • PC reboots regularly

    - by Bob
    Windows XP RAID 5 drives Intel Dual Core processor 2 GB Ram I am running a processor temperature monitor. It does not appear to be overheating. I do not have virus. The PC freezes and reboots. I do not think it is software related, because it will reboot if it is doing nothing. Could it be the power supply? Might i need to replace it? How do I diagnose this? Is this the kind of question that is appropriate here? I am not sure.

  • Help me diagnose Windows 7 pc issue

    - by lkm
    I have a dell pc running windows 7 with the intel i3 processor. Whenever I restart the computer, the os crawls. For example, I move the mouse and then I see it move on the screen 10 seconds later...everything runs slowly. This happens only on a restart (its fine when I turn it on after it has been shut down). Any ideas what is causing this (I haven't installed any new software since buying it). Does it sound like a hardware or software issue? Thanks

  • Need Help Accessing the Vista Wampserver localhost from Virtual PC 2007 running an XP VM.

    - by Reg
    (I had posted this on stack overflow but it was suggested there that I post it here instead). I have a Vista laptop on which I'm running wampserver. I have Virtual PC 2007 setup with Windows XP running on the VM. My goal is to be able to use the XP VM to run IE6 to view the localhost in the Vista wampserver. I'm not interested in having the XP VM have any access to the internet -- only to my Vista wampserver's localhost. The vista wampserver works fine. As suggested on a blog I read, I installed the loopback adapter on Vista and I set the loopback to 192.168.21.1 and I set the xp vm ip to 192.168.21.2. I am able to successfully ping the vista-loopback adapter from the xp vm. I've turned the wampserver to "server online", and I've disabled the firewalls in both the vista host and the xp vm. But for some reason, I still can't seem to get the virtual XP to see the localhost on the vista wampserver. I've tried using the vista //name, and I've tried the ip 192.168.21.1 directly and with the port. For whatever its worth, I'm not able to see anything under the XM VM's network places (though I don't know if I'm supposed to be able to see anything). So at this point I'm stuck and I'm still not sure how to get this XP VM to "talk" to my vista wampserver localhost. Any advice on how to fix this problem is much appreciated. Thanks in advance for your help. -R

  • Developer's PC - worth getting more than 8GB RAM?

    - by Borek
    I'm building a developer PC and am wondering whether to get 8GB or 12GB. It's a Core-i7 860 system, i.e., 1156 motherboards with 4 slots for RAM sticks, dual channel, usually up 16GB (as opposed to 1366 sockets where 6 banks / triple-channel are used). 8GB would be cheaper to get especially because price per GB is lower with 4x2GB compared to 2x4GB. Also the availability is worse for 4GB DIMMs here where I live; those are the main practical advantages of 8GB. (Edit: I should have stressed the price difference more - in the eshop I'm buying from, the difference between 12GB and 8GB is so big that I could almost buy a whole new netbook for it.) However, I understand that more RAM can never do harm which is the point of this question - how much of a difference will 12GB make as opposed to 8GB? Honestly, I've always been on 3.2GB systems (4GB but 32bit system) and never felt much pain from having too little memory - of course there could be more but for instance compiler's performance was usually held back by slow I/O or not utilizing multiple cores on my CPU. Still, I'm not questioning that 8GB will be useful, however, I'm not sure about the additional 4GB difference between 8 and 12 gig. Anyone has experience with 8GB / 12GB systems? The software I usually run all the time: Visual Studio or Eclipse (both should be fine with ~2GB RAM, after that I feel their performance is I/O bound) Firefox (it can never have enough RAM can it? :) Office (~500MB RAM should be enough) ... and then some smaller apps like Skype, other browsers, some background services etc.

  • PC freezes after repeated clicking noises

    - by Péter Török
    I have an oldish PC (Athlon XP 2200, WinXP). Every time I switch it on, I hear a loud "click" first of all, and when it is shut down, again a click is the last sound I hear. Lately it started to behave erratically: it started to click loudly in the middle of a session. First only once in a while, then repeatedly for several seconds in a row, and finally it froze completely. We were not doing anything particular during these times, usually just browsing the web. This has already happened twice in a few week's time period. We typically use it only in the evenings, so when the freeze happened, I just decided it is time for the bed. When it was started up the next day, everything looked fine. Any hints on what could be the culprit? Could it be caused by an ageing heat fan, or dust that has accumulated inside the case? We are backing up all the data stored on it, and then will open the case to look inside, but I thought it would be good to get some background info first of all.

  • Need help toubleshooting PC

    - by brux
    I have had problems since my dog pee'd on my computer. Problem: loads windows fine, at random intervals from 5 minutes to 30 minutes it restarts itself. There is nothing in the event log such as errors, no BSOD, just cold restart. after restarting - sometimes- it POST's and restarts itself at the end of POST. It will do this many times and then finally load windows. The cycle then begins again, it will restart eventually. What I have done: I thought it was HDD at first, since this is the only part of the computer which actually got wet with any fluid ( the case is off the PC and the dog pee'd down the front where the HDD is located). Seatool, the seagate HDD tool, found errors when I ran it inside windows, so I ran it in DOS mode from boo-table USB and ran it. It found the same number of errors and fixed them all. I ran the scan again and it says "Good". I loaded windows and ran the scan and it also said "Good there. So the HDD appears to be fine but the problem persists, random restarts. What else could this be? I have taken the computer apart and cleaned everything and also taken the PSU apart and cleaned it thoroughly. The problem still persists, what should my next steps be?

  • Software developer needs Validation for VA Chap 31 to purchase Macbook Pro vs. PC [closed]

    - by David
    I am currently attending college with a path of software development and working towards my BS thanks to VA Chap 31. My old original Macbook Pro is near dead and no longer upgradable on the software or hardware side. The VA has offered to purchase a PC laptop for me (Because my syllabi says computer required), but I do not want to go backwards. I have a lot invested in OS X software and Mac peripherals, not to mention I prefer to program in an Apple environment. PC vs. Mac costs are so drastically different that I must validate my request for a new Macbook Pro. In my request to the VA, I stated the above and some other topics but they requested more validation. Can anyone recommend issues, reasons, etc. to help me validate this purchase by the VA for school? Thanks in advance for your help, David

  • PC runs very slowly for no apparent reason

    - by GalacticCowboy
    I have a Dell Latitude D820 that I've owned for about 2.5 years. It is a Core 2 Duo T7200 2.0GHz, with 2 GB of RAM, an 80 GB hard drive and an NVidia Quadro 120M video card. The computer was purchased in late November of 2006 with XP Pro, and included a free upgrade to Vista Business. (Vista was available on MSDN but not yet via retail, so the Vista Business upgrades weren't shipped until March of '07.) Since we had an MSDN subscription at the time, I installed Vista Ultimate on it pretty much as soon as I got it. It ran happily until sometime in the spring of 2007 when Media Center (which I had never used except to watch DVDs) started throwing some kind of bizarre SQL (CE?) error. This error would pop up at random times just while using the computer. Furthermore, Media Center would no longer start. I never identified the cause of this error. I had the Vista Business upgrade by this time, so I nuked the machine, installed XP and all the drivers, and then the Vista Business upgrade. Again, it ran happily for a few months and then started behaving badly once again. Vista Business doesn't have Media Center, so this exhibited completely unrelated symptoms. For no apparent reason and at fairly random times, the machine would suddenly appear to freeze up or run very slowly. For example, launching a new application window (any app) might take 30-45 seconds to paint fully. However, Task Manager showed very low CPU load, memory, etc. I tried all the normal stuff (chkdsk, defrag, etc.) and ran several diagnostic programs to try to identify any problems, but none found anything. It eventually reached the point that the computer was all but unusable, so I nuked it again and installed XP. This time I decided to stick with XP instead of going to Vista. However, within the past couple of months it has started to exhibit the same symptoms in XP that I used to see in Vista. The computer is still under Dell warranty until December, but so far they aren't any help unless I can identify a specific problem. A friend (partner in a now-dead business) has an identical machine that was purchased at the same time. His machine exhibits none of these symptoms, which leads me to believe it is a hardware issue, but I can't figure out how to identify it. Any ideas? Utilities? Seen something similar? At this point I can't even identify any pattern to the behavior, but would be willing to run a "stress test"-style app for as long as a couple days if I had any hope that it would find something. EDIT July 17 I'm testing jerryjvl's answer regarding the video card, though I'm not sure it fully explains the symptoms yet. This morning I ran a video stress test. The test itself ran fine, but immediately afterward the PC started acting up again. I left ProcExp open and various system processes were consuming 50-60% of the CPU but with no apparent reason. For example, "services.exe" was eating about 40%, but the sum of its child processes wasn't higher than about 5%. I left it alone for several minutes to settle down, and then it was fine again. I used the "video card stability test" from firestone-group.com. Its output isn't very detailed, but it at least exercises the hardware pretty hard. EDIT July 22 Thanks for your excellent suggestions. Here is an update on what I have tried so far. Ran memtest86, SeaTools (Seagate), Hitachi drive fitness test, video card stability test (mentioned above). The video card test was the only one that seemed to produce any results, though it didn't occur during the actual test. I defragged the drive (again...) with JkDefrag I dropped the video card

  • Install Ubuntu on Asus Eee-PC 1005PE - Dealing with special partitions

    - by MestreLion
    I have an Asus EeePC 1005PE netbook and im planning on doing a massive re-partitioning (going to install Ubuntu, Mint, XP, etc) Ive noticed it has 2 "special" partitions: a 10Gb Fat32 RESTORE hidden partition (used by BIOS "F9 recovery" feature) and a 16Mb "unknown" partition at the end of the drive (used by BIOS "Boot Booster" feature). So, for both partitions, my question is: Can I move/resize the recovery partition freely? What are the requirements for it? (i mean, for it still be found by BIOS when i press F9/Activate BootBooster?). Partition table order? Partition type? Flags? Label? UUID? Can i make it a Logical (instead of primary) partition? Does it must be the flagged as boot? And, more importantly: where can i find any official documentation about it? Ive ready many (mis)information about it... some say Boot Booster partition must be last (in partition table), some say Recovery must be 2nd, that it must be bootable, etc. How can I know what is really needed for the BIOS to use both F9 and Boot Booster? Note: Im using gParted from a Live USB Stick (Mint 10 / Ubuntu 10.10), and ive noticed that, since the filesystem type of the Boot Booster is not recongnized, it cant move or resize it. Can I delete it and re-create it somewhere else? Whenever i create a 0xEF partition gParted crashes and quits and i cannot open it again (must delete the partition using fdisk / cfdisk)

  • Building a new PC, Installing XP, blue screen of death

    - by Tim
    I got a gigabyte barebones kit and am installing windows-XP(SP1) and the initial setup works, then it restarts and goes into the second phase of the setup. Then when installing components (I think that's what it says) it gets half way done and comes up with a blue screen saying IRQL_NOT_LESS_OR_EQUAL. BUT! I had gotten past that by installing windows-XP media center addition Now I am trying to install the drivers for my Asus ATI Radeon 5770 graphics card and I get another blue screen of death that doesnt give much info something about address x0000005. Would you think there is something wrong with something in my system or do you think if I got windows 7 that would take care of things? Sorry for probably not giving enough info. Here is what I have MotherBoard - Gigabyte S-series GA-H55M-S2(v) PSU - Ultra 500 watt atx HDD - Sata serial ATA Seagate Baracudda 7200 CPU - Intel i3 Memory - 4gig crucial Graphics Card - Asus ATI Radeon 5770 1Gig DDR5
