my custom made pc keeps randomly rebooting with a loud buzzing sound in the speakers while playing games. This has been happening since i installed witcher 3 today. on high settings it would happen all the time (overheating?) so i lowered it to low and all that happens is it freezes sometimes. I decided to play cs:go (which has never had an issue on my new harddrive) and now its doing the same thing as the witcher 3 on high! help!

it was doing it before the most recent update and im doing a pressure test on my gpu with msi kombuster and im getting 76c with no crash so far. ill run the witcher 3 and see what i get. ill reseat the ram and gpu tomorrow. EDIT: just tested the witcher before it crashed and only got 67 degrees C within 6 min of gameplay

That's probably the case but it only started doing it after i installed my new sshd. does an sshd use more wattage or is it just a coincidence?
