| 1203117 | 2011-05-18 09:12:00 | i bought a new PC not long ago every thing was fine until about a month ago when it started randomly turning off like someone was pulling the plug. i noticed strange things like the mouse light was still on after it crashed, i dont think its a virus because i have reinstalled windows 7 since the problem began. also ive checked the temps with both the BIOS and a third party software and there all fine. my thoughts was that it is a faulty PSU but im not sure, any thoughts on what the problem could be? my specs MB: ASRock N68-GS3 UCC CPU: AMD athlon ii x2 255 RAM: 4GB GPU: Nvidia 8400 GS PSU: Aywun A1-5000 (500W) from BIOS CPU temp 27 degrees celcius voltage reads Vcore = 1.4 V +3.3V = 3.4 +5.0V= 5.1 +12.0V = 12.1 cheers, sam |

| 1203120 | 2011-05-18 09:51:00 | Welcome to PF1 :) When it shuts down, will it start back up again instantly if you press the power button ? Even though you say random shut downs, try to remember what you were doing at the time - any one thing thats common ? |

| 1203122 | 2011-05-18 23:26:00 | @pctek its dust free, event viewer shows Kernal-power 41 (63), @wainuitech it does not restart after shutdown. It truly seems to be random shutdowns it has happened while, idling, before even booting, while gaming or browsing the web it truly seems to be random. |

| 1203123 | 2011-05-18 23:55:00 | The temp does seem fine but bear in mind BIOS temps are at idle and not what it gets under load. Possible causes: Overheating faulty: PSU Motherboard RAM graphics card faulty or overheating. dodgy hard drive edit: oh and see if you can borrow a psu from somewhere to try, could well be the prob Best to attempt to eliminate one at a time. Run Memetest or windows 7's memory test to check the RAM - leave as long as you can Run prime 95 and check CPU temperatures to check for CPU problems See if your graphics card reports temp's in it's software, try another or onboard if poss. Another thing you can try is booting from a linux live CD if you suspect it's a software or driver issue. |

| 1203125 | 2011-05-19 00:15:00 | corsair, silverstone etc | dugimodo (138) | ||
| 1203126 | 2011-05-19 00:57:00 | Enermax PSUs are not bad either but my preference would be a corsair modular if I bought a new one today. | Snorkbox (15764) | ||
