So this is going for about three days now. When I turn on my PC between the time of 7:30 PM to 9:00 PM it will not boot or either keep on crashing after a few seconds, then about 2 or 3 hours later it will boot. After I run sfc /scannow it will show some files have been corrupted and after it have been repaired and display no integrity violations it will repeat the same thing tomorrow, so the corrupted files need to be repaired once again. If I open it at other times like in the morning,afternoon or midnight it just works just fine. I've turned on Deep Freeze after the corrupted files have been repaired but it will display that some files have been corrupted once gain after I open it a day after. I suspect it is my computer is infected since I was found out some malware prior to this. Can anybody help?
