Specs: OS: WinXP Professional 5.1 SP2 (Build #2600) CPU: AMD Athlon(tm) 64 Processor 3400+ Video: NVIDIA GeForce 7900 GS (1152x864x32bpp 85Hz) Sound: SB Audigy 2 ZS Audio [D800] Memory: 1GB My PC is giving me some pretty annoying issues. To cover the bases I know of first... all of my hard drives are in good condition, I use Disk Keeper regularly. When I try to play games like World of Warcraft, Counter Strike Source, or even sometimes flash games... I'll notice that my PC gets laggier and laggier.. and if I hit Ctrl + Alt + Del, it says my PF usage is around 900 and rising. It eventually crashes and there's this high pitched nonstop beep. Not really sure what the deal is.. my computer has been doing this since I built it.
