I'm having some problems with Windows on my PC.
When i install Windows on my PC, some apps ( Chrome, steam, all the drivers up to date, flash etc.) and when i watch youtube videos or just play games it like crashes, looks like power outage, but it turns on right after it turns off. It looks like it's a power problem, but i have a UPS ( it's APC SmartUPS 700 with a new battery, old but reliable), so it can't be power fluctuation and the Power Supply is decent. I know that it's some kind of problem with windows or drivers, or something in software, not hardware, because when i install Linux Ubuntu it doesnt crash, not a single time.
Temperatures are ok. GPU max 65 and CPU max 55, so it's not overheating.
Please help me, because it annoys me and i really want to use windows.
Thank you in advance!
