My computer recently had a nasty virus on it a couple months back which caused the screen to go white and tell me I need to pay money in order to use my pc. After I send it into get fixed, I noticed an issue in which if I were to open up chrome the computer would make the sound like it's shutting down, chrome pops up but doesn't load(says unresponsive), then after 15 seconds it makes the booting up sound and then it loads up. This happens almost every time I enter a new page,open new tabs, load a video, or play any sort of video game. I asked a computer buddy of mine and he suggested it was the fan, but the fan keeps turning even though the computer 'shuts down'. This is becoming really annoying and has hindered any sort of activity on my pc to a minimal.
Anyone ever seen this before?
