Stumped

[squirly]

Here is what I did. I had my cpu overclocked to 3.49ghz from 2.8ghz. It's a P4 2.8ghz 533mhz Prescott. I have 1.5gb PC3200 DDR 400, 160gb HDD, 4 Optical drives, 2 floppy drives, Radeon 9800 Pro AIW 128mb, 680Watt PS. I increased the cpu voltage from stock to .1 and rebooted and then the pc never came back on since. The board powers up, all fans spinning, harddrives are being accessed, drives are lighting up, but no video. So I tried a new VC, new Mobo, new proc, new ps, new memory and nothing has worked. I reseted the cmos battery, cleared the cmos jumper, left the battery out for 24 hours, unhooked all items from pc except 1 stick of memory, 1 harddrive, and video card, still nothing. Anyone have any ideas?

mobo is a gigabyte p4 titan, both of them.

Your CPU may have died. Can you install it in another system to see if it still works?

Overclocking is potentially hazardous to any component, and if you overclock, you must be prepared to replace fried components. It's part of the game. It does sound to me like the increased voltage popped the CPU.

I did. I bought a new mobo with the old cpy, it booted fine to the bios. i overclocked it but not the voltage, rebooted and it never came back on. I go a new cpu for the new mobo, and still the same thing.

Will the new CPU and the new motherboard boot up with it NOT overclocked?

This time, with the new mobo, it sounds like you just pushed the RAM, AGP, or PCI out of spec. Clearing the CMOS should fix that.

nope..tried that

Did you check the power supply? I didn't see if you did....I would suspect that after a new m/b, cpu and v/c
