GPU Fan Not Working

Specs: Windows 7 x64, AMD Athlon II x3 445 Processir (3 CPU's), ~3.1 GHz, 8192 MB of RAM
Hi everyone, this is my first time posting so thank you in advance for your help.

Last week sometime, I noticed my computer had a virus. I removed it using Malwarebytes, updated it repeatedly and re-scanned the PC until the scan showed no results three times in a row.

However now I am noticing that the fan on my GPU is not working (AMD Radeon HD 6800 Series). I noticed this because while watching a video on youtube, my PC restarted without warning. When I went into the AMD GPU Control software, I saw that the temperature on the GPU was at around 90 degrees C, and that the fan speed said 0%. After enabling/disabling the manual fan control, I noticed that every 5-10 seconds, the fan speed would boost up to 10%, and then drop back down to zero.

I am downloading an updated version of the driver as I am typing this, in hopes that it will fix the issue, but something tells me this may be hardware related, or something else.

Has anyone had this problem? Advice? Suggestions?

Thank you for taking the time to read.

Alright, after installing the updated driver, the AMD control center says the fan is running at 100% (I manually have it set to 100% at all times, because I do a lot of gaming). However it doesn't sound as loud as it normally does. I will test this out and let you guys know if it worked or not, in case anyone else ever has similar issues.

Okay, so as I suspected, the fan was NOT working. It would spin half-heartedly for several seconds, and then stop again. I decided to remove the GPU to clean it out (it was pretty dusty) and I found that the PCI Express port that I was using appeared burned. I decided to try installing the GPU into the second slot, and then the fan started working fine.

So if this ever happens to you. Now you know.

Running fine on another pcie x16 slot? Are u saying the card destroy the pcie x16 4 slot? can we see some images? Do you know you are limiting video card peformance?

Yeah my motherboard has two PCIE x16 slots so I switched it to the bottom one. I'll get some pics up after work. The card is still running really hot, although the fan seems to be spinning faster than before. Also, how is that limiting performance? Ty for the response kuwese.

Pentium D is actually two Pentium 4 Prescott cores(aka hot potato) in one package, and P4 was not a good CPU. Some of Pentium dual core e series(1.8-2ghz) outperform Pentium D 3ghz.

Did u remove the video card heatsink? Post the temp

Hm, I'm still not sure what you mean about limiting performance. I was not able to remove the heatsink because the card is kind of a big package. It's one giant unit, that hooks into the PCIE slot, but the fan, heatsink, and card are all enclosed in a big plastic box.

Also, I THOUGHT the card was working fine, but the fan is not spinning as fast as before and it continues to overheat. It used to be LOUD, but now even when I set the fan speed to 100% it's rather quiet, and when I put my fingers on it, I can tell it is not spinning as fast as before.

U won't see the true power of your video card unless u change the CPU, CPU is making the video card perform slow.
U say it's running hot but we need to know the GPU temp.

When I'm browsing or just doing stuff in Windows, the temp is about 60 degrees C. Watching videos seems to be around the same temp, but if I fire up a game it goes right up to around 90 degrees C, which causes the system to restart at around that temp.

Also I see what you mean now about the CPU.

The GPU temp is unacceptable, something is wrong
-Bad cooler or
-Bad driver

Try to remove the ATi driver and monitor the temp then install the latest ATi driver and monitor. Post back the results.

I did try removing and updating the drivers in one of my earlier posts, but that didn't seem to work. I'm pretty sure I fried the fan on my GPU so I am using a backup one that I had laying around in the meantime.

The back up fan help to cool down the GPU fan right? U can purchase after market heatsink for video card.
