computer suddenly slow and choppy

Hi I was playing game a suddenly the screen freeze and back to normal then freeze completetly thqt force me to reset my comp. After I restart I notice my computer become really slow a choppy. It run smooth for 10 sec and freeze again then back to normal again. I do some research and it look like the hard drive burn out is it true or something else am currently running malwarbyte to see if any virus on the comp thanks
P.S the CPU is running less then 10%

Most of the time, the power supply is the culprit on freezes. In second place is a failing memory stick. But in those cases, Windows usually stays locked up.

If you have a real good friend with a desktop, open his up and temporarily borrow his psu and replace yours with his. If the freezes stop, you have your answer. Buy a new one. Spend at least $50. This is one piece of hardware you don't want to cut corners. Get more wattage, and at least an 80+ Bronze rating. Corsair, Antec, and Seasonic are favored here.

If not, download MemTest bootable iso on his machine, burn it to cd and boot up your pc with it. Run it for at least 3-4 hours. If it finds a problem, you'll see it the bottom half of the screen.

If this shows a problem, test one stick at a time in each slot.

Yah I change the sshd to replace the old HDD and now it run perfectly
