Strange Systemcrashes; please help my pc or he goes out the window gg

[monocytogenes]

hi!
i got some strange pc behavior:
my system:
athlon 1000mhz 133fsb
msi k7t (ms-6330)
256mb no name ram
creative geforce256
sb libe value
enermax 350w

win 2000, sp2, newest via 4in1
bios v2.7 becuase of southbridge bug
vcore 3.45V because of northbridge bug grrrr.....

i had problems with this comp since the start but i cant figure out the problem
the symptoms:
computer crashes when playing 3d games depending on the game (mostly after 10 min, counterstrike sometimes lonkger ~2std, nearly no crashes in max payne)
with crash i mean it locks up and i have to reset
even stanger when watching flash animations it crashes very fast
sometimes ie crashes

so i thougth maybe irq conflict with the sb, sb out comp doesnt start up because of keyboard initiation failure, sb back in comp starts...
4x agp is disabled
the comp gets fairly hot some times, running temp usually around 54°C tops 60°C (i know this is not so good) but i also managed to crash it at 53°C
anybody got an idea what to do? except buy a new comp which i am very tempted to do ;-)
TIA

Get your hands on some crucial RAM (or any other top brand). You really cant do without it. I'm almost 100% positive it's because of your RAM.
