First of all, hello! I guess I'll start at the beginning (and with that, a warning, it might be a bit long). Long story short - a cooler died, I didn't change it (the PC seemed to work fine), a few months later another cooler started to fluctuate, and around that time the PC would have trouble turning on - it'd turn on for a second or two then shut off, until eventually it turned on. The second cooler (out of four?) died within a month, so I changed both. However, shortly afterwards another problem presented; my PC would shut off suddenly, out of nowhere. For days sometime it'd work fine, then boom - it'd shut off on most random things, like browsing, watching a movie (usually within the first few seconds), or playing a game (within a minute or two).
On other times, however, there'd be no problems. I could run the game and the video player for hours, and it'd work fine, same with the browser. It's baffling, really, because when it shuts off, it's usually less than 10, 15 minutes after I turned it on, so I don't really see it happening because of overheating (although I'm no expert really, and I'll upload screenshots of temps later).
When it does shut off, however, it's almost guaranteed it'll happen again (mostly before it even gets to Windows, or if I try running internet ~ movies ~ games again). As I already said, I'm no expert, but I usually know enough (combined with internet) to figure out what the problem is and fix it, but this time I'm at loss. I figure it could be psu (and on that note - the psu fan doesn't run the whole time, it turns on and shuts off every now and then), graphic card, or eventually ram (although I've never encountered a problem with it before).
As for the specs, it's an older build; Pentium 4 (3.00GHz), 1.5gb ram (500 + 1, DDR) Micro Star 7108 motherboard, and NVidia 6600 GeForce graphic card.
I've probably missed something, though. Right, Power Supply should be 420W (or 320), although, I could be wrong (I've forgotten). Either way, other than changing the fans, there was no other changes to the PC components (except 320gb hdd a few months earlier).
Cpu according to HWMonitor (after 20 minutes of playing a game) was around 64-66C; max 74C. As for GPU, it was around 80-81C.
Any help would be greatly appreciated.
