Hi everybody, Finally I got my 6600 GT (BIG), evrything is running fine except videos . My comp just freezes and then restarts whenever I try to play a video file using any app. After restart a dialog box appears saying system has recovered from a serious error I'm using 81.85 driver, earlier used 76. smthng which came with the card CD. I have DX9.c installed. I think its a driver conflict with DX9. I searched the internet and found many ppl experiencing this problem , some were having nforce boards but no one had the right permanent soln. And yes I used Driver Cleaner to remove the driver ( Plz anyone post the right way to remove drivers using driver cleaner, I didnt found it user friendly, I mean what all things are to be added and what is to be done with the driver.cab). When I reduce the hardware acceleration (Display properties->settings->Advaned->troubleshooting) 3 points to the left i.e. at "Disable all Direct 3D and Direct Draw accelerations" the vidoes play fine. I also ran the DxDiag tool and all video tests were successful. I have a dual boot system with Win 98 on first partition. I have installed latest driver for 98 and vidoes play fine. But in Xp it just hangs. Someone on a website said that 71.89 drivers do not have this problem. Will try it and post. My system config: WinXp SP2 AntiVir PE Zone Alarm 5.5.062.011 P4 2.8 GHz HT (Northwood) Asrock P4i65GV, 128x2 MB DDR 400 (Hynix) BenQ 16x DVD ROM Samsund CD RW WD 80 GB Hdd Floppy Drive Intex 300 W LG studioworks 700 E HELP ! HELP! HELP!
