Hey, recently I have been awoken to my PC turning on and making a very high pitched screaming noise, its almost compairable to the anne.jpg scream. I haven't installed literaly anything for the past week, just playing games. Its strange to see my PC turn on and scream at me at 2-3 am each night. Any thing I can do to help? Ive done virus scans with malewarebytes, kaspersky, avg etc. Nothing. What to do?
