I have an NVIDIA GeForce 8600 GTS. According to my app "System Information for Windows", the GPU is running at 63 C right now. All I have done since turning on the PC is run an accounting app and then Firefox in order to ask this question.
My CPU temp is currently 28 C.
I've been having some problems with my PC, and I have narrowed the cause down to the hard drive, RAM, or GPU. Today is the first I noticed the GPU's temp, and am curious if that is too high (and may be causing my problems).
