What is wrong with my computer and graphics card?

[The_Beast_Gamer]

Ok so recently i have been upgrading my gaming computer and the first thing i bought to upgrade was a corsair 750w power supply...then i had bought a nvidea 9800 gx2 graphics card (before i was using amd apu graphics) and when those parts had arrived i put them in my system (i had also ordered a asus sabertooth rev 2.0 and a amd 8350 8 core cpu but they hadent arrived yet) but anyways....the power supply and graphics card had been working great for the first couple days.(accept some weird lag/ shudders problom in battlefield 3 and 4 that i never fixed).....But then just yesterday i was using ppsspp (a psp emulator) and....BOOM complete crash! A bunch of colours on screen and everything!No response at all! I had to manually turn off my pc....i had thought it was just a random crash....NOPE! I had gotten the dreaded code 43....And to make it worst...artifacts....But these artifacts are these ton of moving lines that make most stuff unreadable...i know the card wasnt overheating because the highest they it got was 76 on a chip.....i got it refurbished off ebay...it didnt look dusty...it looked brand new....to be more precise it was a XFX nvidea 9800 gx2....so it was factory overclocked.. and the drivers were up to date and now the computer is using Microsoft display driver...But the lines are still there....even in the bioson the old and new mobo.....so should i try and get the ebay seller to give me a new card or should i do the oven trick?

Artifacts usually happen from high temps, too high of an overclock on the vram, or a card that is going out. What kind of temps is your card running under the stress of a game?

Well before when the card was usable the max i got was about 76-seemed alight.....especially for a old dual gpu card that ran hot

ouuuuh, that's a lot, cards for dual graphics are shit, they really can't take the heat very well, I'm afraid you cooked your card. But the question is why didn't it throttle itself when it was in danger... did you perhaps over-volt it too?

 

[bccorrupt]

76C is fine. You could try uninstalling the drivers, completely cleaning them out, and then reinstalling new ones just for the sake of trying something that won't cost anything, but besides that I would suspect that the card is going out.

I have tried to get rid of all the drivers and any trace of them and reinstalling them before....didnt work.....even though its a dual gpu card can i still do the oven trick and try and fix it?

You can try it. Another idea would be to underclock it some. Generally if a card is showing artifacts that will help quite a bit, if not completely fix it, but only for a short time.

How can i underclock / undervolt it?.....in msi afterburner for both cards everything is greyed out sliders don't work and are blank were numbera should be.....And the line artifacts make it pretty IMPOSSIBLE to barely see anything....but for gpu usage 1 and 2 it shows them going up and down like crazy....can i not change the speed / volts because Windows makes me use Windows display driver? The line Artifacts make it hard to see anything....im using Windows 8.1 if that helps

The GPU usage will usually go up and down quite a bit. What model GPU is it?

 

[The_Beast_Gamer]

Its a XFX nvidia 9800gx2 ...i got it refurbished off ebay for 65$...looked brand new...No dust or anything!

You can try to just unlock MSI afterburner the way you would for being able to adjust voltage on newer cards and see if it unlocks it.

If that doesn't work you can just use an adjustment program from when the card was made like ATItools which is basic, but should work fine.

I literally punished a 6850 a while back with a large overclock and overvolt for almost a year and when it started showing artifacts I was able to use it for about a month longer underclocked even using it for games. Yours not being beaten on so much might last a little longer.

Ok, thanks i will try that in the morning when i wake up and post my resaults....p.s....i updated my very first post on here to give some more information.

 

[The_Beast_Gamer]

Oh and one very important thing i forgot to mention before....both cards give me the code 43 error in Windows! :-(

I didn't know you had just bought it. If it was from a company then return it or make some kind of claim with ebay. That's a 6 year old card. You can get better performance with a new $100 card.
