No video on boot

[yyrkroon]

GeForce 7950GT 512MB PCIe.

Not getting any video signal on power-up. Monitor works fine on another PC. PC boots up just fine, just no video.

If I reseat the card, everything boots up just fine, until next shutdown and power-up...rinse/repeat

What do you think the problem is, card going bad or PCIe slot going bad...haven't tried it in another slot yet.

Drivers are current - updated them 2 weeks ago from NVIDIA.

Could be power - how beefy is your power supply and have you connected the auxiliary power cable that the card needs?

After the reseat, do you get the normal video splash screen during POST?

For shutdown, do you go all the way to power-off, or just to standby?

From a troubleshooting standpoint it sounds like the card is dead, but the comments about the reseating confuses it.

@Nelviticus
power supply is a Antec Pure Power 800W and yes the aux power is connected.

@edfair
after the reseat, everything boots up as normal...all the correct splash screen, etc, everything you would expect from a PC with nothing wrong. on shutdown, its a complete shutdown.

haven't had a chance to move it to another PCIe slot yet, i'm guessing that would be the next step, unless there's anymore suggestion...

thanks,

Does the motherboard have on-board video? It's possible that it keeps defaulting to that instead of the card when you 'warm' boot, i.e. without switching the machine off at the mains. If so, see whether you can disable on-board video completely in the BIOS.

no onboard video. Gotta admit, this is a strange one.

I'm thinking the PCIe slot is going bad, since the video card is working, and stay working if i don't power the PC down.

The MB is a Intel D975XBX, there's 3 PCIe x16 slot on the board, however the 2nd and 3rd slot are only x8 and x4 electrically.

It could be a faulty card or slot but it's worth blowing out the slot with compressed air and (gently) cleaning the contacts on the card with wire wool just in case.

Unless, that is, the card is under warranty, in which case I'd skip the wire wool part as that might invalidate the guarantee.

Since everything works as expected after you do the reseat I would suspect that whatever is the trouble happens on the cooldown and the wiggle required to remove and replace the board resolves it.

Kinda reminds me of the Radio Shack video board that had a heatsink that would fail to connect unless you thunked the case or moved the video board.

Thanks for all the input...

I've talked a friend in letting me use his vid card and see if I'm getting the same result...same card, just different manufacturer.

I'll test it out tonight and provide an update...incase you're curios.

 

[yyrkroon]

my card in another pc does the same thing and the friend card in my pc works like a champ.

time to get a replacement vid card.

Thanks for all the inputs.

Now that's a true friend...that lets you put a potentially bum card in his PC! Treat yourself to a nice new 8800 GT or ATI 3870, and your friend to a brew or two.
