Hi the Fellas!

So, I'm experiencing some odd issues in my PC performance. It's an old PC, about 5 years old, but I've recently formatted him (6 months ago) and it was very fast and acting normally, but recently he has been every slow, crashes some time, mainly when playing some games. In the beginning, I could play Garry's mod with the graphics on high at 60 fps, now, on normal, it's completely full of breaks and slowdowns... I've checked my CPU usage, and sometimes, even with only Firefox being executed, its using 100% of it. So I've decided to Unninstalled a lot of stuff, used disk clean, disk defragmentation, CC Cleaner, but nothing, so i know is not about the HD. Then I ran the anti virus (Avast!), but still nothing, so it's not a virus or malware. I also ran msconfig to kill some tasks and services, but still, the pc is slow.
I also checked the CPU temperature with Speedfan, and in the Desktop, the temperature is 53ºC, I don't know if it's very high...

So, I really don't know what to do more. Can you guys give me some ideas about what to do?
Here's my specs:

Intel Dual Core E2000 2.2Ghz
Nvidia Geforce 8600GTS 512MB
4GB RAM
Western 500GB
 
Try maLware bytes scan for malware. Also boot into safe mode and rerun the virus scan. Use msconfig turn off stuff that not needed in start up.
Look in add remove programs for muilty anti virus programs or anti malware or pop up blockers and toolbars. A lot of new virus are built into fake anti virus and toolbars. Also a lot of free software drops junk into your system. On his CPU temp pick up a tube of theramal paste and clean and reapply it. After a few years it drys out.

First, thanks for your response!

Now, I've done everything you said but still no signs of better performance...
I really dont have much thing installed, I'm only occupying about 20GB of my HD, about 2 or 3 games, etc... I never install toobars or whatsoever, so it cant be that...
About the msconfig, only the anti-virus (Avast!) is enabled in the start-up, and in the "services" tab only the windows stuff is enabled too.
I've replaced the old termal paste and reapplied the new one, but still the same CPU temperature (+- 50ºC) and the same performance :/
