OK so here's my problem:
If I'm the only player in a server (e.g. I start a listen server), my computer hangs within about 2 to 8 minutes after I spawn. Happens on public servers, a dedicated server I installed fresh myself, and a listen server, even a listen server for a 3.0.1 install. This has never happened in CS:S, and it hasn't happened so far if I join a server with players in it. When I say hang, I mean the display loses input, sound card stutters whatever's in the buffer, and the only way to restart the computer is to throw the switch on the PSU (no response to the power button), but the machine does stay on in an electrical sense.
I realize this is probably a software problem on my computer, but I'm hoping someone here has some insight since it seems to be triggered by something in GES.
Running XP Pro SP3. So far I've restored the machine from a ghost image of a clean install (i.e. reinstalled Steam completely), and tried removing my sound card drivers (Creative SBLive! 5.1) and changing my video card drivers (ATi X1950Pro) from 8-10 to Omega 3.8.421 (a version I used for a few years with no problem). None of these changes made a difference.
So right now what I've got is an install of XP Pro that's seen 3 days use total. Older Omega driver for vid card. Current (ca 2003) Creative driver for sound card. 3Com driver that came with mobo for NIC. .NET 2, 3, 3.5 framework. AVG, 7Zip, Chrome, Firefox, IE8, NTFSLink (haven't made any links in the filesystem though), FileZilla, Java, WinAmp 2, VLC, GSpot, Foxit, CutePDF, DVD Decrypter, Exact Audio Copy, UltraISO, Alcohol 120, Steam. That's absolutely everything installed on here from a clean install of XP.
Last time I'd made listen servers for GES was late May, but none of this software is new to me since then. Only difference I can see is that I'd done a clean install to get ATi TV working again. No hardware changes to this machine in over a year.
Any thoughts are appreciated.
