PC Keeps shutting down

I currently have issues with my custom built computer that I built in2008, the problem started mid February when Windows 7 began to shut down out of the blue. This wasn't a hard shut down either, Windows would go through the normal "saving your systems" shutdown. I thought it was a one time thing and didn't think much of it, it then happened again a few days later. I proceeded to buy some thermal paste and removed the paste on both my CPU and GPU figuring I could have some heat issues. I ended up getting temps around 34-40c on my CPU and 54-59c on my GPU. When I did this I didn't have any shutdowns anymore and the problem seemed to go away.

However on March 31st Windows froze while I was listening to music in winamp. I restarted the PC. It worked fine for two days then froze again. I proceeded to install a dual boot with Linux Mint and Windows and was using Linux. I ended up while using Linux had some major stuttering with the sound, then it led to a freeze, I proceeded to restart the computer and ran Linux and it worked for a good 35-40 minutes. I went away and came back to find the PC had shutdown. I proceeded to turn it back on and run Linux to which I noticed as I was using it the shutdown box appeared telling me Linux was going to shutdown. I stopped it and left the PC off for the night.

Yesterday during the day I did a stress test for a few hours on the CPU, temps spiked up too about 60c but the computer didn't crash or shutdown. I also ran memtest86 overnight for about 8 hours and it did 8 passes with errors whatsoever with the memory.

I'm stuck here right now tonight because I booted back into windows today and I ended up having Windows start the shutdown process again about 15 minutes ago.

I did notice something that is odd. I went into the BIOS to check some settings, proceeded to save the settings. The computer would shutdown as usual then I noticed it would start up for 2 seconds then turn off, try to start up again for 2 seconds then turn off then finally start up a third and final time. It did this twice when I saved the BIOS settings.

I am wondering if my issue could be related to my PSU dying or to my motherboard going bad. I checked the mobo to see if any capacitors have blown and I didn't see anything out of the ordinary.

Help would be greatly appreciated

Hello Brian I am no expert but will give you a few good starting points to cancel out a few components. I would start with pulling out you sound card and tv wonder and give a boot up. Then I would try booting with just a single stick of memory. If these fail i would think its one of you bridges on your motherboard going south or north. I have had this problem only once, I pulled off the heatsink on my northbridge and saw that it had blistered badly, no mo mobo. I like gigabyte boards myself. I how ever have never ran into a bad harddrive before only bad sticks of memory.

I'm going to run a stress test tonight using BurnInTest and see if anything happens, I'll report back with whatever information it spits out or if the PC freezes. I'll remove my tuner card in the morning since I don't need it anymore.

I ran the stress test and it passed, no errors appeared. I went and removed the sound card and the Tuner card from the PC. I noticed with the removal of both that I got a drop in temperature by 3-4 degrees overall. The PC did last night try shutting itself down but I have a program that stops it. I did a thorough check of the Motherboard to make sure I didn't have any blown capacitors or leaks this morning when I removed both the Sound Card and Tuner Card, I found nothing that would arise suspicion. So PC is running now in Windows and so far its been up for 20 or so minutes without a problem.

Hope it still up and running. I have had major conflicts with sound cards before. I have an old sound card and only works on some beta drivers I dug up on the creative site. here is the drivers CSL_PCAPPBETA_LB_2_61_49 and XFXA_PCDRV_LB_1_04_0000

I ended up looking into my NVIDIA 8800GT which I began using again. I did some checking to see and it looked as if it could be an issue with the graphics card since 3b usually is a graphical, driver, or memory issue. What I ended up doing was using driver verifier and got two BSOD from it. One when trying to load process hacker relating to its driver and the second relating to Riva Tuner and its driver file. I removed Riva Tuner and process hacker, turned off the driver verifier, proceeded to install NVIDIA'S Ntune fan control program and tried to use it and got a BSOD with it. I ended up removing it, did a memory test overnight just to be sure it wasn't memory, got 15 passes no problem. I did proceed to install Service pack 1, installed a myriad of Windows 7 updates, and two hot fixes, one relating to BSOD and a GUI. So far I have no issues.

I do believe the BSODs were related to faulty drivers and some fan control software. I'm currently using an older nvidia driver from 2012 and having no issues.
