Asus P4P8X (AMI bios) When I booted: ..Checking NVRAM Overclocking failed! then the death blue screen appears (error 0x0000007E, I don't remember clearly) When the restart button is pressed, everything went black I also tried to boot from a floppy disk, but it won't even boot or let me in the BIOS Then: I remove the cmos battery, wait 20 min, then place it in, and power on, it started, I run BIOS and set default settings but it didn't work So I repeat the same action again and use the BIOS recovery from the support CD, recovery was successful but when I reboot, evrything was back from the start (all black again), I repeat several times, but now even if I remove the cmos battery and put it in, everything's still black. This time it stucks, really. Please help me. Thank you everyone.
