Whats up all? I have a PC thats is running a MSI 648Max mother board with P2.4. My old video card was a Radeon 9500 Pro. A few months ago, the computer stopped booting. It would just beep and never post. I put my old Radeon ViVo DDR 64 video card in and the system came up fine. I figured the video card is shot, okay no biggie. I order a new PNY GeForce 6600GT. It came today, and I install it. When I turn it on, it won't post it just beeps like the 9500 Pro did. Now I'm getting frustrated. I call PNY support, they have me put in the old card. Go into BIOS look around, she (the tech) says the card must be bad. Call newegg and have them issue a RMA, etc. Just fit kicks I decide to try it in my old AMD XP1700 with a cheap ECS board. The GeForce is working fine in it, and I'm guessing my 9500 Pro may also. What should I try? Is there something in BIOs I should look at on my MSI board? Any other ideas? Please help. I need to play some BF2 and HL2 dang it! Cliffs: 9500 Pro and GeForce 6600GT won't post on MSI 648 Max motherboard, but Radeon ViVo DDR 64 works fine.
