Computer crashes during or shortly after bootup (REPEAT)

REPEAT*

I have a (home-built) computer with an Intel Core i7 CPU running Windows 7 that has worked fine for several years. Over the past few days, however, it has started crashing (locking up, Blue Screen of Death, rebooting) very frequently. It's gotten worse, to where it now doesn't even get through the bootup process before it crashes. I tried booting from an emergency CD, which worked and showed the program for ~1 min before the computer locked up.

It's clear some component in the computer is dying. My question is, what - CPU, motherboard, memory, something else? Anything I can do to check at this point? I've made backup image files of the C: drive, so if there's a log file there that Windows wrote to while it was still marginally operational that would have helpful information I can probably recover it. Any suggestions? Thanks.

Reply to RGD1101: I've done that - when I was able to boot into Safe Mode it shortly crashed. Now I can't boot into anything.

*REPEAT: I changed my email address and this site is supposed to have sent me a confirmation email. I've requested it twice (& checked spam folder) but haven't received it. The site isn't allowing me to reply so I've reposted this message. Sorry for the repetition!

P.S. Finally got all 3 emails at once & it appears I can now reply.

for a old build, usually is an issue with heat or the psu.

open the case check that the cpu fan is moving and there not thick layer of dust. make sure the gpu fan is moving. check that all the ram is locked in. if the ram is locked in and yu have more then one ram stick. turn the pc power off.drain the system for safty...(pull the power cord from the wall). wait a few min then pull all the ram out but one stick. see if windows will boot. if it will see if it stable. if it is stable swap the dimm if the error pop up again you may have a bad dimm. if your pc a few years old it could be a bad cap in the power supply or the supply is failing if you have a volt meter check the atx power supply voltage on the color wires.

Thanks - I think you're right. The weather was hot (though it's been equally hot before), and with cooler weather the problem seems to have gone away, at least temporarily. I've also added another cooling fan.

No dust, all fans working, etc. Memory ok. Nevertheless, I think the problem was heat. The weather's cooled a bit & things now seem to be working. I've added another cooling fan.
