Whenever I attempt to play certain games (the 1999 edition of Space Invaders by Activision, and certain fangames made with the Multimedia Fusion software or similar products) I can only play them for a short time before certain audio effects begin to loop endlessly (and, in the case of the MMF games, lag the entire game with it). I've tried adjusting acceleration settings (in dxdiag), but nothing seems to be having an effect. This problem does not effect any other games or applications, and seems to occur even when no other programs are open. Relevant specs are as follows; AMD Athlon 64 X2 5000+ (2.6ghz per core) 2gb DDR2 800mhz RAM Windows 2000 Professional w/ Service Pack 4 Gigabyte M61PME-S2 motherboard Realtek High Definition Audio (AL662 codec) 5.1 surround sound speakers Gigabyte GX-NX84S256HE (based off GeForce 8400GS) DirectX 9.0c Updating drivers did not help the problem, and it seems to ; can someone please help me with this, before I end up ripping all of my hair out? Thanks in advance for anyone who may help me. (Also, my apologies if these forums do in fact have a thread-moving function and I've just remade the same thread. >_<) Messing up computers, one dual-boot at a time.
