I have a gaming PC with A10 7670 and R9270X-DC2T-4GD5 graph card. 16GB RAM and a 500V evga Power supply for over a year and a half. The thing is that now it "randomly" shuts down somewhere between the first 20 mins (it can shut down during the boot, during the first 10 min or when I hit CERTAIN programs) I am aware that this might be a virus but whenever I try to run a scan it shuts down at 40ish%. Also, before this happened, I used to get random blue screens in the past 15 days. But now, it just shuts down without any warning. I haven't gotten any more blue screens.
I also updated to Windows 10 hoping it might update my drivers. Yet I am in the same situation.
My knowledge on these matters is very limited, so please, be patient if my explanation is not good enough.
Also I openned my pc and everything seems to be working properly, just a lot of dust (which I removed already)
