Freezing and Crashing Issue with Computer

[MaddLu]

Hi there so I guess I will share the problems I have been having recently and see what you guys think is the problem.

When I play "Overwatch" for a few minutes it crashes and my window closes. I thought it was the graphics card because its about a 5 year old graphics card and a few months ago I updated it to the latest version. The graphics and CPU are about 70c when Im playing, and I have as many fans as possible.

When I play "League of legends" my mouse freezes which causes a bit of an issue. It is an old mouse but it might have something to do with the computer.

Lastly my computer just recently just froze and I had to manually turn it off (holding the on button till it shut off). The parts I have are
Motherboard:
Gigabyte Technology Co. Ltd. 990FXA-UD3

Graphics Card:
S230HL (1920x1080@60Hz)
2048MB ATI AMD Radeon HD 7800 Series (ATI AIB)

CPU:
AMD FX-6300
Vishera 32nm Technology

I would really appreciate any help of what I need to update or buy to get this fixed. Let me know if you need to know anymore information.

Thanks.

Could be a dying HDD. Try running a HDD Diagnostic Tool from your HDD's manufacturer.

What's your power supply? It may be crapping out on you. Things appear to be fine while idling, but once you place a load on your system...

Its been so long I dont remember the manufacturer of my disk, However I did run a windows check and it said it was fine, with no problems. But I dont know how trust worth that is.
