Question PC Crashes - Screen goes black and PC restarts - Help PLEASE!

[M1NDREK0]

Hello dear community!
My name is Francisco and I'm having severe issues for months already with my PC. I'm finally giving up on solving this as I tried almost everything at my reach. I am an experienced user, worked for years with PCs, I even fix PCs for my known people.

This happens with puntual games, like Escape from Tarkov, V Rising, sometimes APEX... but no trouble with other games like Hunt, Mordhau, Valorant.
I have been playing Hunt all night, NO crashes. Been playing Mordhau for 5 hours, NO crashes.

Tarkov example: I CAN play maps like Factory or Labs, but when I try a bigger map, my PC restarts in the loading screen, sometimes it takes more time, I spawn in, run for a minute and boom, crashes again.

Things I've done so far:
-Format and fresh W10 install.
-Renewn thermal grease on GPU and CPU (no temp issues, GPU doesn't go over 50° with fans at 95% speed)
-Bought a new power supply (Gigabyte 80plus Gold 750w)
-Checked GPU performance with Furmark (no crashes)
-Updated BIOS to latest drivers.
-Updated Geforce to latest drivers.
-Tried downgrading the GPU with MSI Afterburner to the max it permits, GPU working at 60% with negative coreclock and negative memory clock. Gets me less crashes it seems, but still crashes randomly in some games.

I don't wanna believe my GPU has come to an end, because it does not give me any trouble with some previous mentioned games, gaming for hours and hours.
I'm starting to thing the MOBO is handling bad voltages or something related, when the game has a peak, it fails generally and needs to restart.

PC Specs:
-MOBO AsRock H77M
-i7 3770k with Cooler Master 212 fan
-16gb (2x8gb) HyperX DDR3 1600mhz
-EVGA GeForce GTX 980ti 6gb
-Power Supply Gigabyte 80gold 750w GP-P750GM
-SSD Kingston 1tb SATA (the most common)


Please let me know what can I try from my PC, other than testing my GPU on another PC.

Thank you

Welcome to the forums, newcomer!

Format and fresh W10 install
Where did you source the installer for the OS?

Bought a new power supply (Gigabyte 80plus Gold 750w)
What PSU were you working with prior to the Gigabyte unit?

Gigabyte 80gold 750w GP-P750GM
You might want to source another PSU that isn't made by Gigabyte or is a higher pedigree Thermaltake unit.

Look in Reliability History and Event Viewer for error codes, warnings, or even informational events that precede or correspond to the crashes.

Thank you for the warm welcome mane, and thank you for your fast answer!

I downloaded W10 from Microsoft official site, installed it normally thru USB drive.

Prior I had a 700w Thermaltake unit which fried due to static problems when I took my PC to the mountain vacation LMAO. After that, I bought a 500w Tt, played for a couple of long months with no issues, and problems begun. Then I thought.. "Well, I'm an a$$hole cause I'm using the best VGA on the 900s series with a 500w PSU, I should try a more powerfull one" and bought this Gigabyte 750w (literally 4 days ago). Installed it, played my main games, no problem at all, but I had to try the ultimate test, Escape from Tarkov. Entered the game, played for 10 minutes and thought "Well problem solved it seems". Suddenly BOOM screen blacks out and PC restarts.

If my memory does not fail, I had this issue VERY sporadically with my previous VGA (MSI 1060 6gb) and the firstly 700w Tt, but I'm talking bout once in a couple of months.

Reliability History has no info, only that Windows had an unexpected shutdown. No critical messages.

Trying to check event viewer RN, don't know why it won't show me the System events, it freezes up the window "Not responding". Anyway I have checked it before and it didn't give me any hint on what the hell is going on with my PC :')
For real I've never experienced something like this before, I feel so sad.

Read this article about your power supply and then decide if you want to keep it. You're lucky up to now if it's just rebooting.

It doesn't surprise me that THE ONE PSU I didn't had to buy, I bought it. LMAO.
I'll cross fingers that mine is not badded out, the blow ups seem to have been with 3000 series VGAs.

I THINK I have solved the issue. I'm still testing tho.
I had the VGA being fed with only 1 cable from the PSU, with 2 ends (it has 2 connectors). I added another cable to the PSU(modular), so now the VGA is being fed by two separate cables for each connector, reliefing the power load I guess. I've read about this detail in this forum, never thought it would affect.
