Dead cpu?

[Underclocked]

Put a system today based on an FIC 503+ and an AMD K6-2 350. I had inadvertently left the vcore voltage set at 2.4v (duh!). In spite of this, the system loaded flawlessly. I then decided to compress the little drive I had installed as D hard drive.
That process seemed to work okay and after reading the "may not restart" warning from Windows, I elected to restart. NOTHING!
No beep, no bios screen, no nuttin'! The ONLY reaction I can get from the system is to remove the memory and start. Then I get a steadily repeating beep. Is this a dead cpu? I've never encountered one (til now?) and am unfamiliar with board behavior if the cpu is dead.
Thanks in advance.

2.4 volts should not kill the chip all the K6-2 are good for at least 2.6 volts. take the hard drive out and see what happens and try booting with just a floppy drive also check the video card.

I have tried booting it with about every possible combination of components in and out, yet get the same result each time. The cpu fan runs (powered from the board), the ide light comes on briefly (when a hard drive is connected), the power led comes on, and the monitor flickers slightly (may just be the slight power oscillation). The only way I can get any beep code is by pulling the memory. It appears the power supply is functioning at least near-normally as the drives will spin up, the keyboard test lights come on, and the LEDs seem to be functional. If the video card were the culprit, shouldn't I get more error messages?
Has anyone encountered this before?

if you have a desent local computer shop take your video card, memery and chip and have them tested on another board. bad memery will give you the same thing no boot no error beeps, some times a video will do the same thing to. so it could be any of those 3

I have now proven to my satisfaction that it IS NOT the cpu, memory, or the video card. That only leaves two things, mobo or power supply. Trying to get another PS now to check that end out. Hope it is a bad PS. Thanks for the input.

If you think it is the mobo I have heard that every now and then the bios chip does not get installed all the way take a good look at all the chips etc,etc. on the mobo give them all a little push to make sure there all seated good your I've even gone as far as to take it all apart and reinstall it all you could have a ground some where from the mobo to the case, or form the power supply to the case ?

any way very welcome and I wish I could have been more help http://www.sysopt.com/forum/smile.gif

Finally determined this is a motherboard problem only. Tried a different (near new) power supply and got the same results. Oh well... maybe I can get it RMA'd.
