Run you antivirus and malware programs. See if that helps. Please also list your computers specs so that we know what you are working with. thankyou
but this problem occured right after i cleaned my pc.here are my specs:
motherboard-asus p5sd2-vm
processor-intel dual cpu e2200@2.20 ghz
ram-4 gb
gpu-nvidia gt 610 2gb
Generally speaking cleaning the dust out of your PC wont make your CPU usage go up.
Turn your PC off
Ground yourself
and re-seat your hard drive cables and power cables, memory and video card if you have it.
Maybe you bumped them and its caused something. I would still run your antivirus and malware programs just to make sure.
