Hey all.
I have an Asus P5W DH Deluxe motherboard with a Pentium D 945 3.4GHz CPU, 4GB of DDR2 533 (3.2GB seen by the OS) and an ATI Radeon x1600 PCIe x16 vid card. Running Windows Vista Business 32bit edition.
Since the other day, I noticed that my office system (the above) has just been shutting itself off for no apparent reason. Yesterday it started doing it and it didn't really matter what I was doing, it would randomly shut itself off. After it did this for the second time, I tried turning it back on again and it would come on for a second and then shut off again. It even shut off on me when I left it idle playing a game on another computer. I am an "experienced" tech so my first suspicion was that it was the power supply. So I ended up switching my Coolermaster 500w with 140mm fan PSU with a new (backup) Thermaltake 430w. Well, after I switched the PSU, for the rest of the day yesterday the system worked fine. I eneding up taking apart the Coolermaster 500w to get the 140mm Fan because the PSU smelled like it was dying. Whilst taking it apart, I also noticed the three or so of the capacitors in the PSU were leaking. Well, my system continued to work properly all throughout the day until just a few minutes ago when I was watching a .asf video in WMP11 and it just decides to shut off on me about 15 minutes into the video. I turned the system back on, reloaded everything, and started watching the video again where I left off. A minute or so later, the system shut off again...
Also note, that I've looked in the Windows even viewer and didn't see any major errors in the event log that looked like it would apply to the shut downs. Even still, if it was a major Windows crash, Windows should BSOD and reboot itself instead of shutting the system off. I have Windows set to only show a BSOD error and NOT reboot anyway...
I also thought it could be something overheating. Well, in the BIOS, the CPU temp is around 55*C and the system temp is around 43*C. SpeedFan reports around 44-45*C idle for the CPU and around 43*C for the system temp. These temps shouldn't be too bad.
I think what may have broken some component that was weak already was the following: I was on a maze creation website that a friend sent me where you can tell it how many rows and columns to generate. Well I decided to go for a large amount to see what it would look like. It took over an hour to process and it still wasn't finished so I closed the website. The shut offs didn't happen then, but a few hours after.
Therefore, I am very worried that it is a major component like the motherboard that it shutting itself off. I was wondering if you guys had any suggestions before I started replacing parts.
