HELP w/ Asus P5A-B rev 1.03 - can't get video to work

[joinT]

I've septuple checked the jumper settings....
Trying to use a K6-2 400 that came with the board. Got a 64mb pc100 stick in there.

FSB: 100 AGP: 66 PCI: 33
CPU 4.0

I've tried voltages from 2.1v to 2.5v

No video card (with a single exception, see below) has powered up the monitor at all. Tried

- 64mb DDR radeon vivo
- 8mb SIS 6236 agp
- 8mb ATI rageXL agp
- Pine 32mb TNT2 pci
- Trident 1mb pci
- many isa vid cards

now, I've read this board is quirky when it comes to video cards. Trident chipsets, TNT's & TNT2's & most AGP cards seem to be very finicky... so now I borrowed a 4mb ATI pci video card (the 4mb version of what the guy who sold me the board was using) & it still doesn't power up the monitor UNTIL I turn off the power from the psu. Then the monitor powers up for 5 secs & then powers down again.

Does anybody have any tips, ideas for me ??
Anybody seen this, where the video card only seems to power the monitor when the mobo is shutting down ??

TIA

I have 2 P5As (well 1 now) The P5A is identical to the P5A-B, just different form factor). One of them crashed while in windows and never would boot back up, it started doing what you describe. I never was able to get the thing working again.

Do you have a PC speaker hooked up to the board? It may be giving POST beep codes.

You could try clearing the CMOS, remove the battery from the board and short the clear CMOS jumper (on some revisions there are no jumpers, just 2 small pads near the battery you short out with a metal object) Look around for it, its labeled.

The only video cards you'll have problems with on these boards are AGP v2.0 cards (TNT2 AGP and above) Radeon based video cards are especially troublesome.

But to me it really sounds like your board may be dead

hey thanks for the reply....
i have tried having the speaker hooked up, no beeps at all.

i tried clearing the CMOS, didn't realize i had to remove the battery.
also, what should I use to clear it. I tried a screwdriver, but I don't know if that one (from my computer tool kit) won't cause it to short.
anything I could use for sure ?

thanks for the help

Hate to tell ya joinT but she sounds dead to me. Had a SS7 board a months ago that had very similar problems. I finally just gave up on it after about two weeks of messing with it.

you can't use a newer vido card such as a geforce or a radeon with an AT motherboard, it isn't a compatible psu, I had a similar problem and I blew the mobo I don't know if it was from esd or from the card

this board has both AT & ATX & I've seen other people post on deja that they have tnt2 or radeon cards working fine w/ the newest bios.

I'm really beginning to get worried

u guys think it might be because this monitor is hooked up through a KVM ?

You could try not going through the KVM. But since you said there are no beeps, its most likely dead, it should beep 1 time when turned on.
