Game Crashing

[Demon_Cleaner]

Well i have that "game crashing w/ loop sounds" thing. No threads on this forum was any help... i did the support over at steampowered.com, the only way i got to play for a while (10 mins maybe?) was to do " -nosound" in the launch options (and the computer ended up restarting). the strange thing is the demo worked fine on my comp...
also after i installed HL2/steam my shift key seems to not work sometimes

Specs
AMD Athlon XP 2600, 1.9GHz
OS - Windows 2000 - Service Pack 4
nVidia GeForce FX 5200
640MB RAM

Edit: Happens with HL2, CS: Source and HL2: Deathmatch

did all of your files update on steam?

 

[Demon_Cleaner]

All files were updated by steam.

640 MB RAM? You sure about that?

 

[Demon_Cleaner]

But im plauged with another problem as well... I've been able to play HL2: Deathmatch a couple times and then all of sudden during play comp restarts
*breaks down and cries*

Yet another problem, got this "'The Instruction at 0x####### referenced memory at 0x#######. The memory could not be 'read' problem. steampowered.com support says i should update my motherboard drivers and BIOs and i have no idea what to do

Indeed, that looks like a BIOS error. One word of advice : GET SOMEONE THAT KNOWS WHAT HE IS DOING TO HELP YOU. If you screw up a BIOS update, it's bye bye compy.
