Problem with graphics card or?

post #1 of 4
Thread Starter 
I recently bought a HIS ATI HD 6870. Everything up to this point, has been running fine. All system temps fine, no problems with anything.

Upon installing the 6870 and with the latest Catalyst drivers I noticed something was 'whining' in my computer, and it seemed to happen when my hdd was loading/doing anything. I also noticed moving my mouse on the desktop contributed slightly, and loading any application. When I tried playing TF2 and monitoring my fps, it was worse than my old nvidia 8800 card. The fps was fluctuating from 20-40-60-230-40-60-20 etc.

I've tried reinstalling Catalyst drivers & trying other versions but no luck. Also, running driver cleaner to clean all Nvidia junk off (did this before I installed ATI card), as well as checking the insides of my computer to locate the culprit sound, and it seems to stem from the hdd - either that or my ears are deceiving me.

The problem went away when I took out my ATI 6870 and put my old nvidia 8800 back in.

Could it possibly also be a PSU issue? My PSU is a modular Corsair HX450w and from all the research I did before buying my ATI 6870, many people assured me that my PSU was enough, as the 6870 was very power efficient.

What do you think?

yeah a 450W does sound a little low for an oc'd Q66 and a 6870.. but if you have been running an 8800 it would probably draw a similar amount of power so i doubt it's the psu... you could under clock your Q66 to take some load off the psu and then see if the card runs okay.... the whine could be caused by a dodgy capacitor or something so if you can eliminate the psu by trying the card in another machine you might consider RMA-ing it... underclocking the card may also be a temporary fix.

Thanks.

One of the first things I thought was the PSU, but wasn't totally convinced. One of the things I tried was underclocking my Q6600 and the problem still persisted. I also lowered the clock speeds of the card, and it made no difference - noise still there.

Unfortunately I don't have another pc to test the PSU or graphics card in.

you might be able to go to your local computer store and get them to test it.. or convince a friend to help..

good luck
