Random black screen while playing games

[dangerousxcv]

Ok so my problem started approximately 2 months ago.So my computer runs perfectly fine with not even a single flaw.My only problem is when i want to open a game (no matter is an low or high requirement one) my screen blacks out suddenly and i cant do anything.Sometimes i can hear sound in background (rarely).I even tried underclocking my Gpu with MSI Afterburner but the results were still bad (it took more time for the black screen to came up tho).I had this pc for almost 2 years and it is still in warranty.So i was wondering does anyone of you guys/gals know a solution for my problem?

~My specs~
System: Windows 10 x64
Graphics card: AMD Radeon R7 370 (2 GB)
RAM: 2x 8 GB Kingston Xfury (blue ones)
Processor: AMD fx(tm)-82320 8 core processor (3,50 GHz)

I have everything up to date and tried reinstalling drivers.I even tried to reset my computer twice

You have a very bad power supply and it sounds like it is finally going. What your are experienceing is a common symptom of that.
What country do you live in and what is the budget for a new PSU, there are often good ones on sale for 30-50 USD
