Hello,
so here is my question ive been going nuts trying to figure this out. I have 2 desktops with the same exact problem one an HP and one an E Machines. I turn them on and they boot just fine i go online for a few minutes and the screen goes black and the power light flashes then i hear the fans kick on really loud and the screen comes back up where i left off. It does this continuously and i am unable to work on it because of the issue anyone ever experience this if so please let me know of any way i can fix this problem thank you for your time!
