Sorry for my bad english

Try a System Restore to a date prior to the issue - System Restore
Also a clean startup - Troubleshoot Application Conflicts by Performing a Clean Startup

I already tried that ,i even reinstaled windows and it still lags

Try loading defaults in BIOS (either first screen or exit menu).
Check your temps. Get HWInfo and Speccy.

Can you see which process is using CPU cycles? Open Resource Monitor and switch to CPU tab, sort by CPU. Check both Processes and Services.

It will make it faster/easier for us to see your screenshots.

Heh, you took the CPU screenshot after it has calmed to 10%. Take another screenshot while it is 80-100%. Don't forget to sort by CPU.

Reinstaled windows to win 8 and still cpu hits 100
The problem started when i reinstaled windows ,not now but when i had win 7

Multi OS issues indicate hardware problems. Or a common app/driver you used.

I suggested before "Try loading defaults in BIOS (either first screen or exit menu).". Did you do this? Need further directions?

already in bios set to default, what should i do next?
