E8500 overclock problem on 945gcm-s2l

Hi. I have a problem with my cpu e8500 whitch should be working on 1333 FSB speed. My motherboard max FSB speed is 1066 but it can support 1333 by overclocking. When i installed processor the motherboard downgraded speed to 2.4 ghz without overclocking. I tried to overclock it, but I managed only to 2.8 ghz. When i tried to go ever higher it just do back to 2.53 Ghz. In bios i also have option to automatic made 1333 FSB speed but when i save that and restart computer it just go back to 2.53 ghz. I am not expert in overclocking and maybe im doing something wrong. I really dont know. A help would be appreciated.

Did you check in Task Manager what process is using the CPU? 43°C in the BIOS is not abnormal, but 68-70°C in Windows with less than 10% CPU activity isn't. I've never see idle temperatures higher than they are in the BIOS. What cooler and is it installed properly?

In task manager idle.exe is always on 100% usage and everything else is on 0. Maybe its some windows glitch because i have cracked windows. Also i bought new cooler and it worked just fine until yesterday. In games i have lower fps, stuttering and freezes.
edit:edit: Guys it turned out that i had a virus. Sorry for bothering and thanks for the response.

Do you have an anti-virus installed?
