Computer locking up after replacing power supply
I'm having a very strange problem with my computer. The other day I went to
use my computer and it wouldn't turn on at all. No fans, no beeps, nothing. However the light on the motherboard was on. Some searching revealed that the likely problem was a failed power supply so I got a new one. Both the new and old power supplies are 500 watts. So I hook everything up and the computer starts up fine and resumes my previous session (it was hibernating before I replaced the power supply) but locks up after about 5 minutes of use. The power and reset buttons don't do anything. So I turn off the computer from the switch on the power supply. But now the computer won't come on again. I come back after about 30 minutes and try to turn it on again and lo and behold it starts up. But this time I get some weird error at startup about how overclocking has failed and the BIOS settings have been reset to default (I have never overclocked my computer). After this it boots to Windows. But then it locks up after about 15 minutes. I manually shut it off again and it won't come back on. So 30 minutes later I come back and it turns on and boots to Windows. This time I clean my registry to see if that helps and restart the computer. It seems to work fine for about an hour and then I leave to go do some things. When I come back I see a blue screen. So I turn it off again and of course it won't come back on. When I can finally get it to come back on it works fine for about 5 hours with no problems and then I shut it off for the night. The next day it still seems to be working fine but then it starts locking up after a couple of minutes after it boots to Windows. What could be the problem??? |

Have you tried resetting the BIOS to safe values? Are All the fans working smoothly, including the new PS? Did you look for bulging caps on the motherboard? |

Sounds an awful lot like an overheating problem to me. If a friend has a working power supply, even if it's not as powerful, I'd borrow that and see if the computer functions well with it. If you bought the new power supply locally, and it's under warranty, I'd take it back for an exchange. If you bought it from NewEgg or the like, return it by all means for a new one. HTH, JG |

Check the CPU fan/Heat sink MOUNTING integrity. It can easily take a hit removing the old PSU and crack or the (yuck!) thermal tape become damaged. --- Printed Books don't become obsolete, Their contents may just become out dated.

Computer locking up after replacing power supply
The researchers' model involved 103 single mutations/recombinations,
six double mutations, and a pair of triple mutations. In the short- term 45 of those were beneficial, 48 neutral, and 18 detrimental. Thirteen of the 45 beneficial steps gave rise to logic functions not expressed by the immediate parent.{{http://farm3.static.flickr.com/ 2549/3670458669_c886d26bd9.jpg}} |
