Computer stats:

8gb 1333MHz Samsung RAM
AMD APU 6600k Quad Core 3.9GHz
XFX Radeon 7770 HD 1GB GDDR5
Unbranded (ill explain later) 500W PSU
Stock fan cooling on CPU, and one 100mm fan on the case.

So i've been having a problem with my Graphics Card. Ill be playing a game for hours and hours, maybe even weeks of intensive gaming (7-10 hours a day), and the graphics card fan will go up to full power, then down to the lowest. The graphics card then stops sending info to my monitor, but the fan is still whirling.

Ive only had the card 5 months, and when I used MSi Afterburner to sent a constant voltage to the GFX Card, it stopped for maybe 2 months? The problem has arose again and using constant voltage doesn't work any more.

I bought the computer pre-built from Amazon WITHOUT the GFX card, and bought the card separately and installed it myself. It's getting supplied power through a PCIe cable adaptor, which may be the problem.

Another potential problem could be the dodgy PSU I have. I don't think its a case of not enough power, but the PSU slowly getting ground to a pulp by my extensive gaming and it's (no doubt) shoddy build quality.

I hope someone has a solution. If you have any suggestions, please leave them below, as this problem has made me use the integrated GPU on my APU, which runs like horse-...

Very likely the PSU if it didn't have a PCIe x16 6-pin connector available. Usually that is a sure sign it isn't able to handle cards that require the extra 75W of power beyond the power provided by the PCIe x16 slot. If you can see the nameplate on the side of the PSU, tell me the rating for the +12V rail(s).

But try this first.
Run CCleaner and do the Clean and the Registry portions both. You may have to run it more than one time if it finds a lot of crap. You may simply be having registry errors, software conflicts, and resource-wasting junk files causing the issue.
