Computer randomly shutting down (always in game) after Fedex Shipped it.

[IdentityZER0]

Hey guys, recently I moved across country and when I got my computer back it was pretty banged up. The back of the case was indented in and the side of the case was somewhat dented as well. At first my computer only turned for about half a second then I undid it and noticed the GPU was a bit tilted. I knew that even though the outside looked banged up it didn't mean that it would not completely work. So I re-screwed it back into place and made sure everything was in good then my computer was up in running again. Although, my hard drive wasn't in its normal spot I put it where it can't really move unless the computer is being moved. So about week or so passes and then I am playing a game and the screen just goes black and everything connected with the computer turns off. The computer turns back on right away but I notice that I get a bit lower fps in the game. I turn it off for about an hour then my fps returns to what it normally is. Since then this issue has been reacquiring quite often. My guess was that the power supply was damaged but the fps drop is strange too. I really hope someone can give me some advice, at the moment I was just thinking of purchasing a new card and power supply. By the way I have tried over and over again to get money from Fedex and no luck. Here are my specs:
AMD Radeon FX-6300 6 core 3.5GHz
AMD Radeon 7750 2gb GDDR5
8GB Ram
Windows 10 64Bit
1TB Hard drive
Power Supply is 350 Wats (I know that's bad and I'm not sure what brand)

Hi, i think maybe your gpu is damaged in some way. I think the power supply adds to the problem and so the combination of those two creates instability in games.Maybe try testing with a different power supply or graphics card.
