New GPU and PC reboots every time I start a game

I just got a new GPU: [MSI GeForce GTX 1050][1] replacing my old card
[ASUS GeForce 9500 GT][2]

I got it to play planet coaster. It was working fine initially, until the next day I noticed as I was playing the screen went black. My monitor stated no signal. My monitor is [VIZIO SmartCast™
E-Series 43" 4k version][3]. The music from my PC was still playing. So I started restarted my PC by pressing the hard reset button. The PC booted back up like normal.

The next day the same thing happened, but now I noticed if I tried to start the game or any game. My PC reboots itself. I have already checked and I have the latest drivers installed for my GPU. My bios also only update from the current bios version and from the description in only has changes regarding optimizing HDD so not sure if it going to do anything if I update the bios. (usually very reluctant to updating bios because from experience it can cause more problems than fixing). Would any one know what could be causing it?

This is the rest of my specs:
[Intel Core i7-870 Lynnfield Quad-Core 2.93 GHz CPU][4]
[ASUS P7P55D-E Pro LGA 1156 Motherboard][5]
[Western Digital Black WD1001FALS 1TB HDD][6]
[Sony Optiarc CD/DVD Burner][7]
[CORSAIR TX Series CMPSU-750TX 750W PSU][8]
[Rosewill CRUISER Black Gaming ATX Mid Tower Case ][9]

I cant seem to find name of brand or link of the ram I have but it's 16gb

I did ran prim95, and nothing happened. no crash
I also ran Furmark, the moment it launched my PC rebooted.

Please help. not sure what is causing this problem

Obvious suspect is new video card -especially with the Furmark crash.

Working with manual, do a complete re-install and see if that works.
