PC keeps rebooting when trying to play certain games or during those games

[squashy]

I recently installed a new graphics card on my old Acer predator pre buit pc that had a geforce gtx 745 in it that I replaced with a geforce gtx 1070.
In some games I play such as: hitman 2 and sekiro they work just fine.
when I try to play plague tale: innocence, it reboots every time I try to boot up the game.

Windows 10 Home 64-bit
CPU
Intel Core i5 4440 @ 3.10GHz
Haswell 22nm Technology
RAM

I know next to nothing when it comes to pcs so forgive me if I havent provided enough information.
I tried cleaning and uninstalling my previous driver, rebooting and installing the latest driver: didnt work

I tried taking out the 2gb ram stick that the pc repair guy installed when he installed my graphics card: didnt work.

someone help me please.

Power supply? Have you checked total wattage?

Power supply? Have you checked total wattage?

I have a 500 watt power supply

PS. sorry for taking so long to respond

Yeah, sounds like a power supply issue but...

"4095MB NVIDIA GeForce GTX 1070 (NVIDIA)"

Uhm, the GTX 1070 is supposed to have 8GB of RAM. Is that GTX 1070 new or used ? Where did you buy it ?

I got it used off ebay

Are you able to run a utility called GPU-Z, take a screenshot/print screen and post it here ?

Well that looks OK.

Is the PC just restarting itself or can you maybe see a blue screen just before the restart happens ? To be sure, go to C:\Windows\Minidump folder (it will ask for permission) and check if there are any files there.

What's the brand/model of your PSU ?

 

[squashy]

Heres a picture of my psu

I dont have a minidump folder in C:\Windows

my computer basically just turns off without warnin. no blue screen or anything, then just turns itself back on

 

[parowOOz]

OK then, no folder, no files.

The PSU isn't bad per se, and it should have enough power to sustain your PC. It does however have it's 12V line split into 3 rails. Maybe the one with the graphics card gets overloaded... that's just me thinking out loud, I'm not sure.

Next step for me would be to try a different PSU, preferably with a single 12V rail. I'm guessing that's not something you can do, right ?

Do you still have your old GTX 745 ?

I do not

and if the psu is the problem, which several people on other forums tell me it is
then ill buy a new 650w. I just want to make sure that theres no other solution before I make the purchase cause money is tight.

There's no way of knowing definitely that the PSU you have is the problem. Like I said, you'd need to test your PC with another, reliable (used in other similar or more demanding build without a problem) power supply to be sure.

You could also try to test your GPU in a friends PC to see how it behaves. You'd at least be sure that the card isn't the issue.

Were you able to play Plague Tale: Innocence back when you had the GTX 745 ?

I got plague tale innocence after the graphics card change. and its not confined to plague tale. it happened to me in total war warhammer 2 and squad so I know its not a problem with the games.

 

[parowOOz]

Any of the affected games worked on the GTX 745 ?

I never played any of these games on the 745. it wouldn't of been able to run them.

 

[parowOOz]

Do you have any friends willing to lend you their GPU for a quick test ?

nope. none.

I just bought a EVGA 650w psu from walmart that will arrive on saturday and I will see if that fixes my problem and if it doesnt ill return it

One thing though, your motherboard doesn't have a standard 24pin connector. From google images I saw it has some weird 12pin connector. If that EVGA PSU is a standard 24pin unit you will need an adapter.
