P4 (dont know the specs, can't turn it on (see below) roughly 3ghz. Was working fine with a GeForce5200 AGP video card. Uninstalled the device drivers in windows, unplugged it - put in a new XFX GeForce 6800XTreme (AGP8x, 138DDR3) in and attempt to power up - all I get is one long hideous beep, nothing comes to life in terms of boot. Beep wont stop unless it gets shut off. If I unplug the card from AGP slot, it turns on with no beep. I tried reinstalling card in slot, no luck, same problem. Any clues? Things to try? - do I need to reinstall the 5200, and tinker with the BIOS? I dont see why it shouldnt pick up this one in the same slot if it was ok with the 5200 right?
thanks for any assistance, you all are great!
