I’ve been having problems with Q3 engined games as well: after 10 to 20 minutes of play (on- or offline) or watching demos, the screen would freeze and I could do nothing else then reset the PC.
What was odd is, I could still hear my teammates speak on teamspeak2 (voice program).
[Just to be complete: what started it all was, I needed a third hard disk. The guy at the PC shop fried 7 hardware items instead, I needed a new motherboard, graphic card, hard disk (2…), dvd player, network card, soundcard…]
After I had all the items I began installing everything again. Fortunately I have lots of backups, no problems there.
Now this problem came, freeze in game…
I tried all of the following: disable soundcard in bios (onboard sound), underclocking cpu, underclocking vid card, change AGP 8x to 4x, install other vid drivers (also the ones that always worked fine on my old vid card), upping the voltages in bios just a bit, set adjustable cpu fan to max, run memtest=ok, run sisoftsandra=ok, etc…
Still the same problem and if you have to reset 4 times during a single game, I can tell you it annoys the hell out of me…
I forgot to install the mouse drivers, did that. At a point I wasn’t sure I installed the vid drivers with firewall and antivirus closed, so did that too.
Old setup + (new setup in brackets):
Gigabyte GA-7VRXP motherboard (MSI MS-6590)
Leadtek Geforce 3 Ti 200 (XFX Geforce FX 5600)
Soundblaster Live (AC97 onboard sound: C-media 8738MX)
512 DDR333 (same)
30 + 60 GB harddisk (30 + new 120)
Windows ME (same)
AMD 2000+ (same)
It’s not a good sign so many people have the same problem…
