• Lag spikes at full CPU usage, maybe video card

  - by Roberts

  I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).

• =?UTF-8?B??= in Emails sent via php mail problem

  - by Camran

  I have a website, and in the "Contact" section I have a form which users may fill in to contact me. The form is a simple form which action is a php page. The php code: $to = "[email protected]"; $name=$_POST['name']; // sender name $email=$_POST['email']; // sender email $tel= $_POST['tel']; // sender tel $subject=$_POST['subject']; // subject CHOSEN FROM DROPLIST, ALL TESTED $text=$_POST['text']; // Message from sender $text.="\n\nTel:".$tel; // Added to message to show me the telephone nr to the sender at bottom of message $headers="MIME-Version: 1.0"."\n"; $headers.="Content-type: text/plain; charset=UTF-8"."\n"; $headers.="From: $name <$email>"."\n"; mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $text, $headers, '[email protected]'); Could somebody please tell me why this works most of the time, but sometimes I receive email whith no text and the subject line showing =?UTF-8?B??= I use outlook express, and I have read this http://stackoverflow.com/questions/454833/system-net-mail-and-utf-8bxxxxx-headers but it didn't help. The problem is not in Outlook, because when I log in to the actual mailprogram where I fetch the POP3 emails from, the email looks the same. When I right click in Outlook and chose "message source" then there is no "From" information. Ex, a good message should look like this: Subject: =?UTF-8?B?w5Z2cmlndA==?= MIME-Version: 1.0 Content-type: text/plain; charset=UTF-8 From: John Doe However, the ones with problem looks like this: Subject: =?UTF-8?B??= MIME-Version: 1.0 Content-type: text/plain; charset=UTF-8 From: As if the information has been lost somewhere. You should know also that I have a VPS, which I manage myself. I use postfix as an emailserver, if thats got anything to do with it. But then again, why does it work sometimes? Also another thing that I have noticed is that sometimes special characters are not shown correctly (by both Outlook and the webmail). For instance, the name "Björkman" in swedish is shown like Björkman, but again, only sometimes. I hope anybody knows something about this problem, because it is very hard to track down for me atleast. If you need more input let me know.

• iPhone contact list emptied due to faulty sync?

  - by i-g

  When I'm in an area with unreliable AT&T cell data reception (e.g. all of Manhattan during the day), my contact list sometimes disappears, and does not reappear for an extended period of time, sometimes hours. Does anyone know why this would happen? Would using manual-only sync remedy this? If I'm using manual sync by turning push sync off, how do I trigger a manual sync?

• How do you kill a process tree in linux?

  - by itsadok

  Sometimes, sending a SIGTERM to a process will cause it to send SIGTERM to all its child processes. However, sometimes this doesn't work. Is there a command or a utility that will allow me to kill a process and all its child processes at the same time? I usually resort to manually collecting all the pids into one kill command, but it feels stupid. This SO question asks how to do this with perl, but anything that gets the job done would be great.

• Why do some emails sent in Outlook 2010 get stuck in Outbox with date set to "None"?

  - by Matt

  I'm using Outlook 2010 against Exchange 2007. Emails I compose sometimes get stuck in the Outbox with date "None" as shown below. These emails never leave the outbox unless I delete them and recompose. Sometimes the problem happens again until I restart the client. Additionally, if I open a good (one with today's date) email from the outbox and then send it, it too gets dated "None" and never gets sent.

• What would cause intermittent DomainKey-Status: failures?

  - by wherestheph

  Every week, we send something like a small newsletter. Sometimes, the header in the newsletter says DomainKey-Status: bad (test mode) Sometimes it says DomainKey-Status: good (test mode) All the other headers in the email are the same (besides expected time and message id differences). None of the email server configuration has changed. What would cause this problem?

• Why is it I can't use my Windows installation both as a host and a guest?

  - by Josef

  I have Linux installed on my harddrive, sometimes I run it as the host operating system and sometimes run it as a guest in Windows using VirtualBox. It's a nice ability, I think. I don't think it's possible with Windows though. Is it because your average distribution includes drivers for everything known to man? Are devices/drivers configured statically in Windows so when somethings changed it breaks?

• command history across multiple PuTTy sessions in SunOS 5.10

  - by foampile

  I have multiple PuTTy sessions open to my SunOS 5.10 server, and I am using ksh, and SOMETIMES the command history is shared among the different sessions and SOMETIMES it is not. I cannot figure out what determines whether it is or is not shared. By shared what I mean is that a command run in one session will be seen as previous command run in another session. I prefer it not to be shared, is there a config setting for that? Thanks

• PNG Compression

  - by T Pops

  At work, on certain projects I have to manage a lot of images. Most of the time PNG files work the best for what I'm doing. With such a huge amount of images, I've tried using PNG compression with PNG Gauntlet but sometimes the file doesn't really change and sometimes PNG Gauntlet reports it would've made the filesize bigger! Am I just maxing out the compression or is there something more I can do?

• Reset network (airport) connections from the command line

  - by Klaus Byskov Hoffmann

  I have this MacBook Pro that has intermittent problems connecting to my Wifi network. Sometimes it helps to disable/re-enable airport and sometimes I have to restart the computer to get my network running again. Has anyone experienced this? And is there a command I can run that would do the same as I do when I restart the computer (short of actually restarting it, obviously) or at least a command that restarts the airport service? Thanks in advance.

• Problem with Macbook air automatically not acquiring free wifi network dns or router address

  - by Rumsfeld

  I have this problem when my macbook air sometimes does not connect to free wifi hotspots. When the problem happens and I try to run the diagnostics, it normally gets to yellow network settings tab. It seems that it for some reason does not acquire automatically the router or dns address. Sometimes after I shut it down and restart it magically connects to the wifi hotspot but it is very inconsistent. Anyone knows a fix for this problem?

• SBS 2003 requires logon for share

  - by Mission

Thanks!

• PC will POST whenever feels likes it

  - by kyrpas

  I'm really sick of my PC and I'd love to throw it off the 5th floor but unfortunately I don't have this luxury right now. The issues started when I moved to a new house about 2 months ago. I didn't have this problem before. Case: Arctic Cooling Silentium T1 with embedded Fusion 550 Eco 80 PSU. M/B: ASRock A790GMH/128M Gfx: ATI Radeon HD 5770 Here's what's happening almost on a daily basis: I wake up in the morning, switch on the PC and all the fans start spinning. 9/10 the graphics fan stays on 100% and I know it won't post. If I'm lucky, ATI's fan stays on full power for a second, then goes back to normal and I get a normal post but that doesn't happen often. No, instead it's just drives me crazy. When I get no POST I'm trying a lot of different things and what bothers me the most is that they all work. But not always. No... That way I could find out what the hell is going on and we don't want that.. right? So, sometimes it manages to POST if I: remove the keyboard remove the power cable for a few minutes remove the graphics card remove the HDD cables do nothing, just turn it on and off a few times Sometimes it doesn't POST even if I do all of the above. And I end up removing all power cables from the M/B, and connecting all the stuff one by one. Sometimes it works, sometimes it doesn't and I just have to pray and wait. What the hell is that? I'm getting pissed of again just thinking about it. The only solution is to leave it on 24/7 but I don't want to do that. It should be able to turn on and off when I press the power button. I'm not asking much. I'm starting to think there's some weird electricity/power issue but I really don't understand what it is. There's no logical explanation about it. At least I can't find one. Any ideas?

• Attaching strace to 100% CPU Apache process - output

  - by knef

  I am having a problem with Apache2 spawning processes that use 100% CPU. Attaching strace to one of such processes produces no output sometimes and sometimes gives this: 2672 17:18:07 poll([{fd=14, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout) 2672 17:18:07 write(14, "\236\3\0\0\3SELECT FLOOR(((price_index."..., 930) = 930 2672 17:18:07 read(14, "\1\0\0\1\2\33\0\0\2\3def\0\0\0\5range\0\f?\0\r\0\0\0\10\0"..., 16384) = 85 I would be grateful for any ideas as to interpreting the above.

• xmonad + urxvt issue: text disappears after resizing

  - by user1212010

  I'm using Arch Linux + xmonad + urxvt bundle and trying to resolve the conflict between xmonad and urxvt. Better to explain with shots: Firstly, open the terminal and get some full-length output. Secondly, create another window, which squeezes the first. And, finally, close it to find out that half of the output disappeared. Sometimes it behaves correctly, sometimes not. Tried to find out why, but failed. Many thx in advance!

• How to view big files on Windows?

  - by user20988

  Sometimes we need to view large files - 30M-100M. Usually we use FAR viewer for this. Sometimes we need to copy to clipboard long traces from this file. But it is possible to copy only one screen in FAR viewer. What can be used for this purpose? It should be GUI and freeware. UPDATE: We need to have ability navigate over the file and see updates of the file in the meantime (eg tail -f)

• How to stay connected on remote desktop even if different user tries to connect

  - by Darqer

  I'm logging through Remote Desktop to windows 7. Some other users sometimes try to connect to the same computer, then a message box pops up with information that I have 30 seconds to block this try or I will be logged off. Sometimes I'm away and then I'm being logged off and when I come back I have to log on again. Is there a way to turn off this functionality for single user. Is there some application that always breaks this login process ?
