i had bought a biostar p4m800 pro-m7 mobo with a 3.06ghz cpu. i hooked it up and it would not boot it would turn on like it was going to (the fans were spinning and such) but nothing came on the screen and i heard no beep. so i turn it off and tryed it again same thing then tryed it again and it worked good but every time i shut it off i had to turn it on a couple times for it to work. when it was working it randomly shut down and then now it will not boot up (black screen fans spinning no beeps) i have tryed a new power supply, working agp card and the onboard video, different ram, and different hdd's i even unhooked everything but the ram and cpu and still no go. i have also tryed starting it with a screwdriver and it does the same thing.
