I bought an AMD 3200 XP 400 fsb cpu as an upgrade for my 2400 which has ran awsome for 2 1/2 years now. My mobo is a Gigabyte (cant remember model #) with 400 FSB. When I installed the 3200 I left all the old setting the way they were <auto> and turned it on problem is no video came on so I changed the settings manually and same problem. So I changed the mobo to an MSI delta 2 (both mobos are on nforce 2 mcp chipset) and I had the same problem. Both mobo's work cuz I put the 2400 back in and it runs fine on both of them. I have 512 and 256 pc3200 mem and video card is a 5950 Gefore FX. HELP before i put a bullet in this processor................
