Well I have a 5 year old system that I built and it randomly restarts, sometimes 10+ times per day and it is beginning to interfere with work. I'm typing as fast as I can right now, hoping that it doesnt restart before I get this posted.
P4 3.0Ghz core
Radeon 9600 pro graphics card
Soundblaster audigy SE sound card..
Running Windows 7 with 2GB of memory and 200gb of hard drive space.
I have no idea what to do to diagnose this, please help!
I dont get a BSOD or any kind of warning, I did change out the power supply although I went with a cheapo 350w one. It seems like it most often fails whenever I try to install a program or when I'm running certain programs which makes me think my HDD might me bad.
First you can run some basic tests, try memtest, run it multiple times (let it loop 3 or 4 times) and make sure your ram is good. Check your temps, are any of them abnormal? Clean out your case, could be a simple overheating issue caused by a dirty heat sync.
I agree it could be a matter of heat. Download speedfan 4.40 and run it see what kind of temps you are getting. Also what is the ambient temp in the room and in the case?
If it is mostly when installing or using a program it could be heat or ram. Also when running chkdsk use the /F trigger to fix any found errors on the drive. As a bench tech I found that the power supply contributed to 90% of most PC problems, not sure why but it seemed to be the base of the problem or at least part of it. The rest seemed to be adware/spyware, viruses, memory leaks caused by improperly uninstalled applications or installed ones.
To be honest it could be a lot of things, your computer keeps log of everything, especially Windows 7 and how it organized. You can find teh critical menu in event viewer and it will tell you about power failure, restarting or shutting down improperly when its happening and you can dig around to find a lot of info as to why.
Okay... Heres a bit more detail to whats going on. My computer only restarts when its being used. I can let it sit all day and it wont restart. When I go to install a program like Microsoft Office then bam restart about halfway through at the same spot every time. I think it may be a bad hard drive but I'm not sure.
Just reinstalled win7 same thing... Tried installing WinXP Same thing different program.
I went to install ZoneAlarm Pro and it started acting up. Finally got it installed but every so often it randomly restarts. I'm guessing it is either trying to draw from a bad sector or a bad spot on the memory.
Blah... What do I need to do to determine bad HDD/ Bad Memory?
I've tried running basic tests and both appear fine but I'm convinced otherwise.
The +3.3 and + 12 volt outputs are a little low, but in tolerance. The -12 volt output is out of tolerance if it is being read properly, but because it doesn't provide any meaningful power to the system, it really doesn't matter.
The -5 volt reading is bogus. No modern PSU has a -5 volt output.
