I am having a problem I can't grasp. I turn my box on and i just get a blank screen and no beep from the cpu. I've reset the ram, checked all the cables. I've reset the cmos, replaced the cmos battery. The bios is up to date according to the manufacturer's website. After I reset the cmos I finally get a beep from the cpu and it takes me into the bios to set the cpu speed manually. I load the setup defaults. Disable boot virus checking and the other settings seem fine. I save and exit and it gives me a blank again. If I leave it long enough it'll finally beep and take me into the bios and tells me my cpu halted because of an incorrect cpu setting. It's a p4 1.6 and that's what I set it to. 1) could it be my cpu is fried? 2) could it be my motherboard's cmos is fried? 3) any other suggestions. Sorry for all the text. I'd appreciate any help. Thank you. P4 1.60a ghz 256 ddr 2 hard drives, 1 cd-rom, 300 Watt PSU ASUS P4S333 mobo

when you set the bios settings are you using 100mhz for the cpu frequency?

I am using the default settings and yes the cpu/pci frequency is at 100/33. Is it supposed to be on something else. That's what the default setting goes to when I set it on 1600 Mhz cpu speed. I also ahve the VCORE setting on auto and in the hardware check of the bios the cpu is using from 1.5 to 1.52 volts. Thanks. Maybe i'll try some thermal paste and then try swapping with a cpu from the store. Thanks again.

here are my hardware temps: mobo 29 C/ 84 F cpu 29 C/ 84 F cpu fan speed @ 2500 rpm vcore 1.5 - 1.52 V
