PC Randomly black screens and freezes

[ThyFeared]

So this has happened twice in the past 10 minutes and i've no clue why. I had Minecraft, Firefox, and iTunes open. My Specs are :
 

• CPU
  Intel Core i5-4440 3.1GHz Quad-Core
• Motherboard
  Gigabyte GA-H81M-HD2 Micro ATX LGA1150
• RAM
  Kingston Black 8GB (2 x 4GB) DDR3-1600
• GPU
  XFX Radeon R7 260X 2GB Core Edition
• PSU
  Corsair 430W ATX12V

It has happened multiple times and it's getting quite annoying. Also when it freezes it keeps playing music for a little bit but then it freezes it. Also before I posted this the music kept playing and it just stayed at a black screen.

It could possibly be a virus or malware? do you have a malware scanner such as malware bytes or an antivirus software such as avast

Backup important files and reformat.

How would I do that?

Do you have anything to backup to like a USB flash drive or external hard drive?

I have my 1TB external HDD

How would I do that?

Put your c disk drive data on an external hdd or if you have multiple hdd's in your rig then backup to one, fresh install windows and format your boot drive that you used previously being carefull not to format your backup if it is on an internal hdd

Backup important files and reformat.

Use that and backup your c drive, first you should get an antivirus like avast and try to scan your pc

COPY your important files to it if you haven't already. Copy, not cut.

Do you have an OS disc?

sounds like it could also be an overheating issue have you checked your temps? when was the last time you cleaned the PC of dust?

My CPU is idling at 44C, and my GPU is at 46C. I cleaned dust 2 days ago.

It's really hot in my room because the sun is usually on my side of the house.

What are your load temps? run prime95 or another program like that and watch your temps

So I downloaded Prime95 but which tests should I run?

I would set it to Small FFT since it is the most CPU intensive test

How long do I run the tests?

keep it on for atleast an hour though for a true stress test you want to run it for 12hrs but since you are just checking temps 1-2 hours will be fine it will run your CPU at 100% the hole time

Just make sure to keep an eye on it in case overheating is the problem, you dont want it overheating more than it might have
