Hello! I bought an nVidia (evga) GTX 550 Ti card close to the start of May, installed it, and it was working fine. Games played well at 1080p at full frame rate with no problems. Then, about a week and a half ago (so three weeks after installing the card), my computer would start randomly rebooting...at first just one freak occurrence, then once every few days, up to the point it couldn't be up and running for more than 5 minutes. I was using a 500 W PSU, so I replaced it with a 700 W model...same problem. I've now removed the graphics card and have been running smoothly for 3-4 hours so far. The card specs recommend a minimum PSU of 400 W, so the 500 W and current 700 W should be more than enough to support it.
I dualboot to Ubuntu 12.04 and Windows 8 CP...same problem in both. In fact, a reboot was triggered even just being booted in memtest86+, so I doubt this is a driver issue. I was, however, able to run a pass in memtest86+ failsafe mode, but I don't know if that's significant, or just dumb luck that it stayed on for that after rebooting twice in non-failsafe mode of memtest86+ (no memory errors). Besides rebooting, it would occasionally just freeze the display in Ubuntu and Windows, and not reboot by itself. There was no useful information in the Ubuntu logs, which acknowledged the kernel was going through the boot process again but did not log any shutdown. These reboot problems happen even if I'm not doing any CPU- or GPU-taxing operation; simply browsing in firefox or even being away from the keys has triggered a reboot.
The CPU is always in a suitable temp range, and there are no thermal problems logged in Ubuntu. I strongly suspect the graphics card and am about to RMA it, but I figured I'd check here to see if anyone else might offer some other diagnostic advice. Unfortunately, I don't have access to another computer where I can pop this gfx card in and see if the same problem occur, nor do I have an extra graphics card to check if the motherboard pci-express slot is bad (there's only one pcie slot on my board). Looking online, I find most people with defective gfx cards get them dead on arrival or get some obnoxious BSOD that points to the gfx card (I've never gotten a BSOD), and I was surprised that this card worked so well for a few weeks and then suddenly brought on these problems, so I wanted to check here and see if that sounded plausible. Thank you very much for any advice you can give on this matter. I will update you if I have any problems with the card now removed, but so far, this is very much longer than I've been able to go without a reboot.-- el Aprel ( facta- facienda) 00:46, 7 June 2012 (UTC)
Update: After removing the graphics card, I noticed that giving the whole computer case a gentle shake also triggers this problem, so it must be a loose connection somewhere, but I'll be damned if I can find it. The obvious point of interest was the PSU connection to the motherboard, but I've checked that and it's secure. Again, I've tried two different PSUs, so it's not a problem with the connecting wires themselves. I'll probably have to resort to taking it apart and reassembling it, since no loose connection is visually obvious. If that doesn't work, though, what are some diagnostics I can do to see if the problem is embedded in the motherboard itself? Thank you.-- el Aprel ( facta- facienda) 18:48, 7 June 2012 (UTC)
I'm learning php, so I did a "proxy" to test my 'skills', I showed it to someone experienced in netwroking. He managed to acess my computer files (He even downloaded some files, and pasted them as a proof) and access my network.. I asked him several times how he did it but he didn't show me..
Anyway here Is the function that get's the files, as you can see, the function that gets everything is file_get_contents, how he managed to do it?
$url = $_POST['pageurl']; $opts = array( 'http'=>array( 'method'=>"GET", 'header'=>"Accept-language: en\r\n" . "User-Agent:php" ) ); $context = stream_context_create($opts); $contents = file_get_contents($url,false,$context);

What is the price to put video ad on youtube (the video ads that plays before the video start)? — Preceding unsigned comment added by 201.78.132.208 ( talk) 05:35, 7 June 2012 (UTC)
Whenever I but a pendrive or a portable hard drive - say 1000 GB portable hard drive, I dont get to use the entire space in it. In the case of the 1000 GB hard drive, I am able to use only 930 GB. So is the case with pen drive - around 95 % of the space is only usable. Why is it so ? — Preceding unsigned comment added by 117.193.139.99 ( talk) 08:09, 7 June 2012 (UTC)

Hi all, I remember back in the 90s people used to tell me you couldn't catch a virus just from being connected to the internet, and you couldn't catch anything from a webpage unless the owner of the page had put one there (or, say, unless a virus on his computer had put one there). Nowadays all you hear is that a (Windows) computer only has to be connected to the Internet for a few minutes to catch its death of cold. What has changed in the meantime? Is it that I used to listen to people who didn't know what they were talking about? What is the situation for Mac and Linux? It all seems rather strange to me, and it sounds like a rather basic thing to be able to prevent a computer from catching a virus except in the case of downloading and running software. Note that by "downloading" I mean in the sense of being able to run downloaded software from the start button, rather than in the controlled environment of a webpage, as happens with javascript. IBE ( talk) 13:29, 7 June 2012 (UTC)
Interesting answers - thankyou. So does that mean the only true vulnerability with Windows is the checking for updates? If you configured it so as not to check for updates, would it be safe, at least until you visited a dodgy porn website? It just strikes me that it should be simplicity itself to protect a computer from unsolicited code. Stuff you download and run can obviously be malicious, as with anything (even offline) that asks for your private information, but stuff just jumping onto your system looks preventable. Does anyone know the situation with Macs? IBE ( talk) 05:42, 8 June 2012 (UTC)
Thanks again - so if the problem isn't auto updating, is it just what Taemyr says, that user expectations for interactivity are high? Because this still seems inherently fixable. Again, I still find it very strange that a remote blackhat can get a computer to download and run some software when all I was doing was registering a connection. Cloud computing is a very small thing to me, and seems a small thing to gain for an insecure computer. Why should the threats be so blatant? IBE ( talk) 12:04, 10 June 2012 (UTC)
I think that I have asked this before but mislaid the answer. Can I charge my iPhone with my iPad charger please? 85.211.222.224 ( talk) 14:07, 7 June 2012 (UTC)
Can you suggest me some good compilers to make Java software? Cambalachero ( talk) 15:37, 7 June 2012 (UTC)
