Hi those in the know, I recently had to replace an MSI X800XT 256mb AGP because it died slowly. I have now got an Inno3D Geforce 6800GT 256mb AGP, this lasted all of about 10 minutes and now basically kills my PC. The symptons are: In a 3D environment the graphics completely distort and system locks up. In a 2D windows environment the screen will become all speckled and again lock up, this also happens in a DOS environment with loads of white dots appearing. I am now forced to use my old Sapphire ATI RADEON 9600XT which has never given me any problems whatsoever, and still isn't. I am wondering that since the latter graphics cards that I have used briefly use external power from the PSU, that might be blowing them, but then wouldn't it blow everything if it was faulty? My system specs are: PSU: 450W Mobo: Asus A7N8X2.0 AMD Athlon 2500XP 1GB PC3200 400MHz 2 x 80GB Hard Drive 1 x DVD ROM 1 x DVD ReWriter Sapphire ATI Radeon 9600XT which works fine. WinXP Home SP2 My PSU specs are: It's Jeantech Model: JN120F-450-AP. Voltage: 115V ~ - 230V ~ (it'll be the 230V since I'm in the UK) +3.3v = 30A (250W) +5v = 45A (250W) +12v = 22A (264W) Max overall = 423W Current: -5v = 0.5A, 5W -12v = 1A, 12W +5V = 2.5A, 12.5W If anyone can offer any suggestions before I RMA yet another graphics card to Ebuyer please let me know. Thanks, A really annoyed Cyrus79.
