Help with a broken graphics card.

Jack P · Sep 13, 2014

Hello
I'm unsure if my graphics card is able to be fixed. Earlier today my PC shut down unexpectedly whilst playing Team fortress 2, I could smell burning coming from my PC. I tried using the motherboard graphics and an old graphics card, which both worked fine. Also this was it's first launch of any game with a new hard drive, running linux. It was running Windows before the new harddrive; does this have any inpact on the card?
Any help would be apreciated. Thanks.

Graphics card: Radeon HD 6670

What wattage/model and brand PSU do you have? Altough 6670 is very undemanding in terms of Power, an extremely poor quality PSU can still not operate with that card on load. Its unlikely to be GPU if its new.

The Power supply I'm using is 300W I can't find the model; although the original PC was this http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01042513&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=3435320#N971. It's still using the original Power Supply. Thanks

Seems to be the PSU, have you played with this card on this PSU before? I've digged out this thread:

I am assuming you were able to game with that card for a year right? I'm certain its the PSU passing off.

MeteorsRaining :

Yeah it'd been fine running games for about a year. So you think it's the PSU that needs replacing, and that the card's fine? I'm able to buy a new PSU if it's the case.

The burning smell is most probably coming from PSU's molten capacitors. Replacing it *should* solve the issue, try to open up the case and check the PSU up WITH THE OLD CARD on load.

MeteorsRaining :

I've loaded both the intergrated graphics and the original graphics card with the PSU. Each allow me to use my PC, but when I use my 6670 card it doesn't give an image on my monitor.

When I opened my case I found that there is a group of wires from my motherboard to the case which were resting ontop of the graphics card's fan, it was completely stopping the fan from moving. I think that was the cause.

MeteorsRaining · Sep 13, 2014

So after adjusting the wires to a better position, were you able to use the new card on load without any burning smell or black screen?

Jack P · Sep 13, 2014

MeteorsRaining :

There's no buring smell anymore although it's still a black screen.

MeteorsRaining · Sep 13, 2014

Silly question but have you connected the monitor to Gpu's port?
Also, are you able to POST or do you get black screen even before that?

Jack P · Sep 13, 2014

MeteorsRaining :

Yeah I've connected the monitor to the GPU by VGA cable. I also tried using a DVI-VGA adapter to try the DVI port. And with the black screen; it never transmits an image, I know it's on by the Power button's lights and the LEDs in my keyboard and mouse both light.

Change the psu, that should end the issue.

Yeah I would have though it would throttle down but I guess it didn't. Maybe the thermal throttling doesn't work right in the Linux drivers?

In any case blocking the fan seems to have fried it

MeteorsRaining · Sep 14, 2014

Thermal throttling will work when gpu is under high temp usually with full load, definitely not at startup. It can't reduce the gpu clock when it's already idling.
And gpu won't get that hot on startup even without fans that plastic starts melting.
It's the psu in my opinion.
