Question Screen Flickers then black screen flashes vigorously afterfew hours of use.

[noisejaegger]

I have this AMD FX8350 Build which is now 5 years old and inside it I have Graphics card which is 7 year old. Until last week Everything was fine but then after 1 or 2 hours of use screen starts flickering and then vigourously gets black flashes. Computer does not freeze though it works fine. Also I replaced DVI to HDMI cable as I thought it might be problem but it still happens. I am using my PC with a LED TV using DVI to HDMI Cable . Please help as I dont know what to do.

List your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Might want to include the age of the PSU as well as it's make and model, not just it's wattage. If you're running off the iGPU and the issue persists after uninstalling and reinstalling your GPU drivers + reinstalling your OS, then your iGPU is failing.

Regardless, might want to post back with specs. We'll move on from there.
