As of late I am encountering strange problems with my PC.
It's a fairly new PC (bit more than a year old, self-build (not by me))
I used to get a BSOD every 2 weeks or so. A restart always did the trick and it would stop happening for some time.
For the past week my screen froze almost every day. No BSOD and no text, just some strange blue blur covering my screen (looks like those dead pixel stripes, but all over the screen). After about 5 seconds, my PC restarts itself and the problem will be fixed most of the times. Sometimes however my screen will get past the bios-screen, then turn black and the screen lighting turns keeps turning on and off. After a certain number of restarts (somewhere between 1 and 5) my PC will start normally.
I'm no good with computers at all, but I checked the temperatures of the hardware, nothing there. I also ran some diagnostic programs but nothing was found.
Can you guys offer any advice what I could do or what part might cause the problems?
Thanks in advance,
P.S. I'm not a native speaker so there might be some mistakes... Forgive me
