Hello guys, i need some help.
It started a month ago, my computer was slow and took too much time to boot, i used windows 7 at that time. So i decided to format it and upgrade to windows 10. Everything was going fine i successfully installed it, used for 2 or 3 days, and when i was playing a game (League of legends) suddenly the screen froze and blacked out (it happened before upgrading a few times, and didn't completly broke the boot, that's why i posted it here) and i had to restart manually, then at windows start up the video was distorted with display bugs but i could still move the cursor and put my password, at welcome screen it froze and i had to restart again. I didnt know what to do so i made a bootable usb with windows 10 setup and installed it once again, worked for 2-3 days and yesterday it froze while i was playing Starcraft 2, the same exact thing happened, even the welcome screen part. I thougt it was windows 10 and reinstalled windows 7 today but it froze again at restart after downloading video drivers and i couldnt boot windows(same video distortion problem).
I think the problem here is my video card which is a Radeon 7800 HD Series, i tried cleaning it and checked all hardware but didnt find the problem, it also works perfectly on safe mode. I don't have any ideo of what to do right now, would apreciate any help.
