BIOS/CPU speed problems
(Click here to view the original thread with full colors/images)

Allright. My bro-in-law sent me his old gaming system. It's a Asus P3V4X mobo, 128mb RAM, ATI All-in-Wonder Pro AGP2x video, PIII 667 processor. 30 gig HD. The system booted and worked when he shipped it.
I take it out of the box (which was extremely well packed) and when I boot, the POST screen shows PIII 333e proc. The BIOS screen immediately flashes, reads PIII 667 with warning that improper CPU speed setting was used during last boot up. I have about five seconds in which to use the keyboard, wherupon the keyboard freezes.
Here's what I've tried.
Removed/reseated all cards and the CPU itself.
Reset CMOS, tried known good CMOS battery.
Set dip switches according to manual (this is a jumperless mobo, but tried both jumperless and jumpered mode--same result)
Tried different keyboards, tried using USB keyboard.
Set BIOS to defaults and saved (in the scant seconds of keyboard access I have).
Another thing I've noticed, and only by accident. I plugged in the monitor and turned on the power to the monitor, and the underside of my arm was resting on the chassis of the case. I can feel a low electrical charge, which disappears when I shut off the power to the monitor. Can't feel it with fingers, only with the sensitive skin on the underside of my arm!
Anyone have any ideas? Thanks in advance

hmmmmmmmmm
does it still freeze when you boot to dos? only other thing i can think of is to flash the bios.

I can't boot to DOS, unless you know of some keystroke combination I can use when I power it on. It's not set to boot from floppy, and I can't get to that screen to change it in the short amount of time I have keyboard access! It's very frustrating...

This a long shot, but you might try to re-seat all the power connections.
Another, more extreme option, would be to pull the mobo and make sure that when you re-mount it, it's not grounding out on anything.
I can't see how this could of been affected when it was shipped, but you never know.
If there are any extra cards in it, like modem's or sound cards, I'd try removing them and run it that way to see if you can't eliminate the electrical short.
I suppose it's also possible it could be something to do with the wall plug it's plugged into as well.
Just shooting off some idea's for ya'.
Good luck, and come back with anything you've tried and what changes it made.

One more thing, replace the battery on the motherboard

The problem was that the CPU wasn't getting enough cooling--replaced the CPU fan and all is well. Glad I didn't fry the chip. I posted this problem on about 6 help forums, and not one person suggested I check the CPU fan. So maybe this will help someone else in the future! Thanks for your ideas!
