Are you still within your warranty period from the store which you purchased the PC from?

I recently bought a new Laptop PC…no major problems but a lot of glitches (none with Avast, btw). I did System Restore and finally System Recovery before contacting the store salesman. He said there is no reason to be doing such things on a new PC other than it being a defective machine and that I should return it for a new one (which I did). Luckily, I was within the 14 day grace period. I have a new machine and it is working great!

Apparently, they do not test individual components now before shipping new computers (like they did in the old days).???
