My pc is constantly crashing and was having trouble turning on from high cpu usage. Constantly spikes to 100% even when idle. Its an i5 3570k @ 3.4ghz and an h60 cooler.

No viruses but for some reason malware randomly appears on my pc sometimes but is always instantly removes with kaspersky. Mobo: Asus z77 v-lk RAM: Gskill ripjaws 1600mhz PSU: Evga 850w Bios havent but updated since I got the board. Could that be a problem?
