The title is pretty vague but I don't know how else to explain it. I don't believe it's a virus problem because I scanned it multiple times, but if someone gives me some tips and it doesn't work efficiently then I will try the security forums. When the computer initially boots up, all is running quite up to speed. Then the fan starts to blow loudly and causes everything to slow down. I have almost no programs running, at least only one. I cleaned my PC a while back but will do so again tomorrow with a can of compressed air. I upgraded to a new video card and had a second HDD installed. If someone could give me a program that runs a diagnostic on my PC and shows all the hardware or just ask what hardware you wish to see so you can see if it's the cause of the fan and the slowdown. I also defragmented a couple times recently.

It's a Dell Optiplex GX240. I'm not sure which fan it is but I believe it is the power supply; the fan is facing the back of the case so I can see it through the filter of the case. it's the new HDD (Hooked on by an IDE cable if it matters) which has too much RPM or my motherboard can't handle 2 HDDs. I'm not really hardware savvy so I don't really know all the inside-outs of a PC.

is it a stock video card or aftermarket? if its aftermarket, it could be overheating, causing the video card fan to speed up to cool it off more, and tasking the power supply thus slowing down the system. but it could also be a failing power supply, or possible a CPU overheat. hard to tell, kinda need more information about the internal components.

I was wondering if there was a program that could analyze the PC's components so I can post it here. You can ask me what components you want to know about and I'll post it. The video card is stock, I bought it from Fry's. I'll give you the exact model when I come back later today but it's nVidia.
