Could it be a bad GPU?

Hello,

I have just recently built my new computer last Christmas with a Radeon HD 7770, so its only about a year old. About 2 days ago I was playing Outlast at a solid 60 fps at high/ultra settings. now I can hardly break 15 fps at the lowest settings possible. Also, my PC used to idle at about 30-32 degrees Celsius, now it idles at about 58-60 degrees Celsius. Could this be my GPU or is it something else? What should I do?

This is called Thermal Throttling.

If you suspect your CPU is overheating then there are a few steps that you can try:

Open the case and check for dust, especially on the heat sink, fans, and the vents to the outside – your CPU can only be cooled effectively if cool air comes from outside the case and is pulled over the heat sink by the fan – dust can be removed manually or with compressed air
Make sure your computer is not in an enclosed space – a computer in a stereo cabinet may not get enough cool air
If you have replaced the heat sink then be sure that it is rated for your processor, is firmly attached and is using the recommended thermal paste. CPUs need to dissipate a lot of heat and tiny obstacles can slow this process
Unfortunately some computer cases are just designed poorly. If your case is badly designed then your CPU may be trying to cool itself with recirculated hot air. In one test a poorly designed case was fixed by simply adding a plastic tube that directed cool air from the case vent to the CPU fan and this lowered the CPU temperature by 20-25 degrees Celsius! However I don’t recommend trying to fix poorly designed cases yourself – buying a case that is properly designed is a better option.

Thanks for the answer. I pulled out my GPU, blew it out with compressed air very thoroughly, as well as my CPU heat sinks. It did lower the temperature to 45-50 degrees Celsius, however I am still experiencing terrible fps even with the least demanding of games. Perhaps it could be something else?

Update: Using RealTemp I'm getting 32 degrees Celsius. Still experiencing poor fps.

I don't think its my PSU, but I'll check it.

Also I have attached a photo of a screenshot I took about 5 minutes ago of what appears to be artifacting, but then again, I'm no professional. NOTE: The white boxes are not artifacting, they are covering up personal links regarding my school.
