Hey there!
I upgraded my GPU, RAM and PSU about a week ago and everything worked perfectly fine until yesterday evening when my PC suddenly shut down while I was playing a game. After encountering the same problem a few more times, I shut it down entirely and thought the problem would resolve itself until this morning - it didn't. It keeps shutting down when starting a game and I mean that in a literal sense as I don't even get to see the starting screen. I've tried different games, deleted and re-installed my drivers, checked the temps and I just can't seem to find the problem.

i5 4570
MSI GTX 970
8GB RAM (Corsair Vengeance)
Cooler Master V-Series 550w

Nothing is oc'ed despite the i5 using its built in turbo boost.
I'm totally drawing a blank but I'm really hoping it's an issue that can be easily resolved.

Thanks in advance!

I'm not sure if the problem still persists, but if it does:

have you checked Event Viewer? See if it tells you anything around the time of the shutdowns.

It's possible the system is BSOD'ing and then automatically shutting down.

Also, try running Memtest86+ (Download Here: http://www.memtest.org/#downiso) to check for errors in RAM. Let it run for at least 10 passes. If you do have errors reported from Memtest86+, check RAM settings (Timings and Voltage) in the BIOS to make sure they are set to the RAM manufacturers specs. If the settings are correct, try swapping the RAM into different DIMM slots on the motherboard. If this doesn't work, RMA the RAM.

If you aren't getting a BSOD, it could be your PSU. Most of similar problems are...

Both Checkdisk and the Malwarebytes full system scan turned up empty.
And what exactly do you mean by "detailed" build? For starters, I'm just gonna add what I left out above:

Mobo: Gigabyte GA-H81M-D2V
HDD: 1TB Seagate

You could check it in another PC maybe.

Good luck.
