CCPD 208 Posted December 22, 2010 Share Posted December 22, 2010 This week for some reason my PC decided to randomly shut itself down now and then. Sometimes it does it a couple of times in few minutes, and sometimes it just keeps working. A couple of times it went blank after I accidentally hit it with my knee (system block is on the floor). My PC is very old but I never had anything like that. I cleaned it, but it done it again as soon as I loaded it up. All cables inside seems to be fine, so I assume it could be either power supply or power cable. Any thoughts? Link to post Share on other sites
Wolf68k 10 Posted December 22, 2010 Share Posted December 22, 2010 First thing I would do is try a new PSU. Link to post Share on other sites
anus 422 Posted December 22, 2010 Share Posted December 22, 2010 Yep, I recommend doing the same. An ATX PSU would do. Also, did you clean everything thoroughly? The heatsinks and fans specially. Could be an overheating issue. Link to post Share on other sites
Tommy-Vercetti19 2 Posted December 22, 2010 Share Posted December 22, 2010 This happened to my really old computer, there was so much dust it completely f*cked up the PSU. As everyone else said check your PSU. Link to post Share on other sites
CCPD 208 Posted December 28, 2010 Author Share Posted December 28, 2010 @ All - Thanks all for your help. I cleaned all the dust. Now it shuts down only when I accidently bump the case. How do I check my PSU? @ Warlord. - Are you talking about 750W CIT ATX Power Supply? Can I get a cheaper replacement? Link to post Share on other sites
Wolf68k 10 Posted December 28, 2010 Share Posted December 28, 2010 The only way to really check the PSU is with a multimeter and then you have to know how to use and what to look for. Link to post Share on other sites
anus 422 Posted December 31, 2010 Share Posted December 31, 2010 (edited) You could buy a PSU now and reuse it for your new rig. So even if the issue isn't your PSU, it still wouldn't be a waste. I wouldn't get CIT though as they are low quality. This Antec 400W would do for the card I'm planning on putting in the build (HD6870), but if you want more power so that you can upgrade in the future without having to upgrade the power supply, this Antec 520W would do . The best Maplin has is this FSP Bluestorm 500W (which is an excellent PSU). This would be a solid alternative to the Antec 520W too. Edited December 31, 2010 by Warlord.

OverTheBelow 238 Posted December 31, 2010 Share Posted December 31, 2010 Maplin overprice their stuff, just making sure you guys know. I used to work in one of their stores for about a year and a half. Link to post Share on other sites
