After my psu deciding it didn't want to work anymore I grabbed a new psu only 580 but it does for me to run my Radeon 6950 hd however the PC has now decided it doesn't want to recognise the gfx card.

To make things a tad more confusing the gfx card works and outputs a signal to one of my monitors. But won't recognise the other one anymore nor will the PC recognise the gfx card itself properly.

I've tried everything I can think of. I've updated the bios and updated gfx card drivers even tried the new beta release drivers but still won't recognise the card or the second monitor.

Any ideas before I give up with everything and spend the best part of £3k on a new PC that I don't really want to spend this side of Xmas. I'm literally livid with the thing now...

You tired clearing the CMOS?

 

Unplug the power, take out the battery and change jumper settings to clear cmos for a few mins. Put jumpers back, re install battery and then boot up.

Can you try the card in someone else machine? That'll tell you if teh fault is with the card or the rest of your machine.

 

If the PSU went it can take other things with it especially if the GFX has it's own power. Or maybe the mobo. Mobo faults can be wierd.

No luck I'm afraid.

I could do, but I really am not convinced the car is the problem :(

 

Could well be mobo related, if that's the case I will just give up in a fit of rage.

Does the PSU match the specs for the GFX card (linky)? GFX cards can pull a huge feed by comparison with other components so if the output to it is too low it could cause the card to appear faulty.

 

As said above it could also have been the PSU failing has taken other components with it.

 

Unless you have a spare system to try the card on you are kind of knackered as it could be the card or mobo and without trying the card elsewhere there is no way of knowing which is faulty.

Yep the psu is fine.

I think I'm going to have to get an old PC down out the roof and have a play wanted to avoid that but oh well more dust and things flying around the office. :(

Update:

Works fine in another machine and swapped psu from that machine to this one and still having issues argh this is driving me mad....

Maybe the PSU has blown the motherboard? How did it fail, big bang puff of smoke or just dead/no power?

Just no power... Interestingly enough I've managed to get the gfx card recognised now I think... Stay tuned within the next hour I'll either be back up and working or the PC will be going down the stairs ready to be scrapped.

Why does technology make you so angry? :(

Final Update: After the most traumatic 8 hours of my life so far.

 

Done. Fixed. Sorted. I've learnt a lot. I'll explain:

 

IF you disconnect the gfx card and put it back, it works... No idea what I've done differently but clearly something. I feel like a right plonker but it's working now so I shall no longer rage

Could have been a bit of crag in the socket, it does happen.

 

I've picked up a tower before now that refuses to boot, chuck it in the boot, a few speed humps and crappy roads get it home and it fires up straight away with no other problems !!

Sounds like the card was not 100% correctly seated. Glad to hear it is sorted without too much trouble (8 hours isnt too bad for PC repairs)

True.

 

I'm wrestling with XP on an old box, fifth format and re-install at the moment !!!

If it was this I am very upset that it took me so long though! :(

Yeah, I guess so. It should have been done in less than 10 mins though it was only swapping a PSU.

 

True.

At least it's not Vista

Vista would be far easier to be honest, newer drivers than 2005 would help no end.

That's likely it. You maybe just nudged it changing the PSU. Cards can work themselves out of the slots sometimes just with thermal expansion and contraction.

Agreed - never had much of a problem with Vista tbh. Mind you I did buy the PC it was on after SP1 came out so by that time it was pretty stable.

 

Main reason for getting rid of the PC was that I needed more memory for Photoshop and Vista (32 bit) wouldnt recognise any more than 4GB without a bodge (which wasn't guaranteed to work). New PC runs sweet as anything (running Win8). Mind you I have not seen the horrendous car crash that is the "Metro" screen in about 2 months due to using ClassicShell.
