blown computer revisited

well
today marked another day fighting the computer: i just want it to stay alive long enought to grab me some stuff off bittorrent -
fat chance. it lives anywhere from 5 minutes to 5 hours. then just locks up.
so i started digging around thinking maybe i could upgrade the cmos/bios and fix a few problems. sure, i can get a new processor and mb for 150$, but that's 150$ i'd rather spend on vacation.
so i take it appart and launch bios to check out processor tempature.
74 centegrade at idle. now, i don't know about you, but that seems pretty toasty for idle, especially an intel - and this baby is NOT overclocked.
maybe that clip breaking off means my heatsink is not on square. so i go to take off the other clip and promply break those brackets too. oh well, no big deal.
well, the heat sink is clogged with dust, but it's still sucking air. maybe i'll just clean up everything and zip tie that baby back on the motherboard!
that's done and so far: sp2 is almost installed. i've not checked on the working temp of the processor, but my guess is i've solved the problem.
