PC Crashing Randomly and I have no idea why

Hey everyone, I was hoping I could get some help with this, sorry for the huge post, but I really need help:



So I've been playing Prototype on my 4 month old PC, and it would occasionally crash within the game (like every hour or two). The computer would shut down, then moments later restart back up. I assumed from overheating problems of my video card because its temperature would reach up to 80-85c, so I got EVGA Precision to control the fan, and now I don't let it's temperature reach above 60c. After that, it would crash less, but still crash (same way, shut down, then moments later restart). So I turned all the graphic settings down to minimum (before this I was running them at full), and the crashing ceased all together. I beat Prototype and all was happy.



Now though, my computer crashes seemingly randomly while not in a game (same way, shut down, then moments later restart). But now, half the time on start-up, it will give the error “Overclocking failed! Please enter Setup to re-configure your system. Press F1 to Run Setup. Press F2 to load default values and continue." (I have not overclocked anything ever) I've reset my BIOS settings to default, and checked all the settings, and to my limited knowledge it seems fine (many settings are on auto though, is this a problem?).



Originally it seemed it would crash when the computer was at load of the RAM (if I had like 10 programs running and such), but it would crash even if the computer was not at load after a time. One time before windows had even booted. I got Everest to log my computer component voltages and temperatures to try and narrow down the problem, but as far as I can tell all readings show normal. I checked all power connections and it all seems fine. I leave the case open and have an extra desk fan blowing into the case to seemingly no result. I was worried about my RAM being hot to the touch (cannot keep my finger on it for more than a few seconds before being uncomfortably hot), but what I am actually touching is the heatsink of the RAM, so I cannot make an assumption about the temperature of the RAM itself, though it runs at a normal voltage of 1.50-1.53v all the time. I’m not sure if the RAM running hot is a problem.



I am not sure how to diagnose a power supply without a multimeter, but I have not ruled out that the problem is caused by my power supply. Maybe not enough charge? Does anyone know a good way to ensure that my power supply is fine?



It is also relevant to note that once a crash occurs (after maybe a couple hours of my computer being on), consecutive crashes occur more frequently, sometimes within 5 minutes or less (to me implying an overheating problem).

I want to say its either the Graphics card overheating, or your PSU is on the fritz.

Hey, i solved the problem. I bought a 750w PC Power and Cooling PSU and problem solved (the PSU was giving voltage spikes on the +5 and +12 connections). I'll never go cheap on the power supply ever again. Trying to save 15 dollars just cost me 100. Now I know.
