V3 3000 5-second hop???!!! (AGP)

[SiNFuL]

Oh man...alright so I've had this card and my computer (PIII 450mhz 384mb ram) for a while...and I used to play CS a lot...and it ran GREAT. I ran at 1280x960 OpenGL(MiniGL) with no problems. Then one day I decided to download "The Specialists" (A Half-Life mod) and I noticed it kept crashing. Then i went back to CS and even that crashed. Long story short, my vid card was all f'd. After trying all the latest drivers (Amigasport 3.0,etc), everyhing worked beautifully except for a glitch/hop in the game that occurs exactly every 5 seconds. I've tried restricting the fps,etc and nothing works...How do I get rid of this bloody 5-second hop??? Thanks ahead!
