Is for some other issues.
I don't see make, model, age, and if you knew to keep the vents and heatsinks clean. There are also machines that will die over time so it's important to share make, model and age.
Also share a Web Speccy report from https://www.piriform.com/docs/speccy/using-speccy/publishing-a-speccy-profile-to-the-web which members can read and comment. Such comments can help but like you know the only cure is when an idea works. You must try.
So, for a week or 2 now my laptop has some serious problems. The first problem that occurred was a freeze of my entire pc( couldn't even shut of num lock) during a game of league of legends. I then shut my computer down by holding the power button. The screen went black but my computer kept on running for a few minutes. Now I'm having weird problems now and then. Sometimes I could start up the pc with no problems but then if I would want to play a game (e.g. CSGO) it would freeze again. Other times my pc would start but the screen remains black. I reinstalled my graphic card last week cause I thought that was the problem, well it was not. I reinstalled windows but kept my files( all apps where removed), but that was also not the problem. I can boot in safe mode and that works but that's no solution ofc.
Please help me,i'm desperate!
(oh, I also tried the "get the battery out and hold the powerswitch" thing, doesn't work)
