Hello everyone. I'm having an issue with Counter-Strike: Source lately. I used to run Vista Home Premium 32-bit on my machine, but went back to XP, and ever since I've had problems with my games locking up. Any game will do this too! Not just counter-strike: source. If it takes a large load of cpu usage, the game locks up. It seems to me that World of Warcraft and games on the Source engine from Valve are the worst for me. My system specs: CPU - AMD Athlon XP 2100+ @1.7GHz (Rated at 2.1GHz) Video - PNY NVIDIA GeForce 5 FX 5200 128-bit Memory - 1GB Corsair DDR 266 SDRAM (1 x 1GB) Sound - Dynex 5.1 PCI Sound Card I'm not sure why my computer is doing this from DOWNGRADING to a earlier version of Windows. I've tried reinstalling everything again and it didn't work. Any help would be appreciated.
