This looks like a hardware issue, maybe heat, maybe a bad videocard, maybe power, or motherboard. Does Windows' event viewer tell anything useful?
Now ask your hardware expert friend to find the cause.
Lately, my computer started crashing after 5-30 minutes of activity. One day it was working just fine, but the next it started to have problems. It is homemade (put together by a friend of mine) and is about a year old.
What I did notice about the crashes is that it doesn't always crash when I'm only using my SSD. For example, I installed League of Legends on my SSD and my pc doesnt crash when I'm playing it. But I also installed Hearthstone on my SSD and then my pc does crash.
Also, to describe the crashes, sometimes the screen just goes black, and my screen shows it doen't get a signal, and sometimes the screen just freezes.
AMD FX(tm)-6300 Six-Core Processor 3.50 GHz
8.00 GB RAM
64-bit, windows 7
NVIDIA GeForce GTX 760
Things I already tried:
- Updating drivers
- Check for malware with AVG and malwarebytes (no problems)
- CHDSK disk check
- Probably something else but I can't remember anything I did
I hope someone can help me with my problem
