6800GT help please

hi i have had a XFX 6800GT card for ages and its been fine, today i left my computer running and went afk, when i came back it had reset/crashed, and upon loading up im getting graphics glitches in 3d programs, that make games etc unplayable, it was fine before it crashed, ive:

Rolled Back windows
Reinstalled Drivers,
Reinstalled Direct X
Cleans my Card of all dust fan and sink is fine.
I dont believe its a monitor problem as the gltiches are accompanied with an increase in computer lag, if it was a minotor issue there would be no lag?

I just dont get what has happened to make it go strange so suddenly, my computer is self built so my knowledge is ok not amazing butok :) , any help greatly appreciated thanks

Got a Asus K8V board, 2 gig ram and nothing else important i can think of, oh and the psu should be fine as its been fine for months? everything else is working ok off it.

I do hope its not just died, i really dont want to buy anew one atm...

Could simply be a component on your card has finally failed. A lot of problems can simply come down to wear and tear on parts, whether it's from high temperatures to screwy voltages.

It could be the power to the card that's not doing so well. Reset the card, reset the power connection.

If possible get another card in just to test your PSU is still fine.

ive tried unplugging my secondary hard disks and cd drives on the psu so there smore power available, didnt help, tried changing the AGP to 4x didnt help, guess i can try a new psu but i dont have the feeling that its that, thing is it happened after a windows crash which makes me think its software related just feels like software, any other software things i should try changing that could affect it?

Definately not software, because you haven't installed or updated anything. The symptoms point to hardware failure, which caused the OS to crash (always try and write down the info on the blue screen). The continual failure of the system to function also support a hardware failure, software failures rarely persist over reboots unless linked to a corrupt file or bad driver (which you haven't changed)


You need to test the card in another system to try and determine whether the failure is on the graphics card or on the motherboard. A new PSU *might* help, but I'd test the card in a completely new system first.

In order of likeliness to be the problem:

PSU - How exactly do you expect a faulty PSU to manifest itself? Bizarre and untracable errors, that's how.
Graphics Card - in-game corruption suggests potential compoment failure/overheating of GPU (check temps in games if you can...keep Nvidia tools open so you can Alt + Tab to desktop instantly to see the temp.)
Motherboard - this is the bridge between the two, potentially something going wrong here.

checked temp it seems fine, i tried it with HL2 i get graphical errors and slow down but no high temps

Quick question, do you have mcafee anti-virus?
Sounds crazy but on city of heroes we traced down a graphics problem to mcafee, it was considering part of the drivers as a virus and blocking them :rolleyes:

Other than that it sounds like the most probable cause is
1- PSU, as a PSU ages it loses power and voltages become less stable.
2- Graphics card, components do die, could be that it did overheat and that has damaged something.

To eleminate software/drivers your best bet is a clean reinstall of windows. :(
If you have a spare hard drive (doesn't need to be large) then you could unplug your current hard drive, plug in your spare and do a clean windows install on that.
By unpluging your current Hard drive and useing a spare you should be safe that you'll not be wipeing anything by mistake.

Well i think im gonna get the card checked at a local pc shop, where i got the psu from, and if it turns out its faulty hope its in garauntee, if not i can get a yet another new PSU, which would be my....5th i think since my first ever pc :) they do seem to just...wear out, the only good thing is it has spurned me into spending £1200 on a m1330 laptop, something ive been meaning to do for a while as a backup/workhorse.

Dont think its a specific software prgram as ive not installed anything i havent had for ages..but it still might be some corruption of data causing the error, as apart from the glitch and lag in games the card is behavin normally...also sometimes the screen blacks out on me in windows, very rarely, so thats another symptom

Well I mentioned mcafee because it was a simular problem, everything was fine then problems started, it was tracked down to a mcafee update, once mcafee was removed the problems went away (and overall performance went up :rolleyes:
I think both norton and mcafee work by cripplinging your pc before a virus can do it ;)

The way to advoid buy lots of PSUs is to buy a good one to start with :P
generally your looking at £40-50 (online prices) minimum, if you paid £30 in a shop then it's going to be junk.

well i bought a really good enermax psu, cost me £65 . it lasted less than 6 months, so i gave up on good psus, the cheapers ones lasted longer than that one :)

It is a good PSU and should more than cope
RMA it ;)
