Pc random shutdowns

by Mnight7 / July 14, 2010 11:53 AM PDT

For the past 2 weeks my pc keeps shutting down randomly, but not very often. There is no blue screen, just shuts off. Sometimes if I try to wake it from sleep it shuts down a few seconds later, but boots up fine after that. sometimes it will run for days before it shuts down again, and has always been sleeping or idle. I have tried a different power supply, power cord, surge protector, changed outlets, ran a memtest, and changed graphics cards. I have been monitoring temperature and nothing seems to be running too hot to cause a crash. I have also looked at my motherboard and cant see any visible damage or capacitors that look bad. I did check the event viewer and got a kernel power error which I will post below. Also if needed my specs are:

OS: windows vista 32 bit
Processor :AMD Athlon 64 X2 4400+ @ 2300 MHz
Ram: 3gig
Motherboard :ECS MCP61PM-GM

Hopefully someone can help me figure out what may be causing this to happen. Thanks

In that case

In that case, since you've already ruled out most of the things I would have suggested, I'd say you have a set of bad caps on your motherboard. Google "bad caps" and then compare some of the pictures to your system. Not all bad caps will bulge or leak like that, but if you see that, then you know for sure that one is bad.

Since you've done the typical checks, I do suggest strongly you reverify the "bad caps" again. Its not always apparent the damage of a bad cap. Next, because you run a AMD cpu, these tend to NOT like any temp variation and they go call on system system down, rather than shift to slower and thus cooler mode, still depends on cpu type. The other side to this, if this system has ran for sometime, re-apply the thermo paste on the cpu, and do it properly. Aged thermo paste or the OEM type thermo tape doesn't last long under duress if so ran. Also, you didn't mention if this system is OC'ed, or constant high demand output can be telling on an AMD cpu as well. No matter what the cause, once you locate it, I strongly urge you maintain a well cooled system case. Understand once an AMD is compromised, it may not quit now but linger its effects, so if you have access to another AMD cpu, try it.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
