MSI GTX 970 Issue

[enterprise-psi]

Hello everyone and happy new year to all.

I am guessing the problem is with GTX970, since before the upgrade my computer was fine.

Yesterday i bought a GTX970, to replace my aging HD5850. I erased previous drivers with DDU, installed nvidia, everything went fine. After 5 minutes, computer reboots. Like i pressed the reset button. While watching a youtube video.
I am looking around, checking the voltage and stuff, then after 8 minutes, a second reboot occurs. I then realist i forgot to unistal the amd's steam alike, forgot its name, the one where when you play, you gather points, and then the reboots stopped. I though this is it , i played skyrim for an hour, then sniper elite 3 for another hour. Then i run furmark, and heaven benchmarks. Everything is fine. Then while in desktop, tweaking the ini of skyrim, another reboot. 🙁

Googlng around, i installed afterburner and checked the "keep voltage steady option" so i hope this is it.

Any other ideas would be really helpful.

Check if your PSU can handle it.

But when the card is under full load, either benchmarking or gaming, i have no reboots. And i guess 750w is enough.

Old PSU's dont support the sudden voltage spike of Maxwell cards, which can go from sipping to big gulps.
Surprises the PSU's emergency shutoff.
Check if the PSU's rails handle the appropriate voltage.

That sounds fair. But how do i check if my PSU can handle the appropriate voltage? Any tips?

 

[Jay Lavistria]

Should have writing that says it supports 12V on the PCI-E rail cords.

Well i am at work atm, and can't really check it. But from what i read here, it does support it.

Could be a defective GPU or the PSU has just aged.

Well my wife will work from home today, so i told her to use my computer. It's been 4 hours so far and no reboots.

 

[enterprise-psi]

And it just rebooted lol. How i can be sure its the PSU ? What if i buy a new one, and it reboots again.

SO i left heaven benchmark running for 4 hours, and had no reboot issues. Temperature stable @ 62C. This is so peculiar.

Could it be that the card is PCI Express x16 3.0 , and my motherboard is PCI Express x16 2.0 ?

 

[Jay Lavistria]

No, all that would do is make your GPU weaker, but not disfunctional.
Is your Motherboard GTX 900's ready?
Perhaps its in need of a BIOS update.

I had the F6 bios, which was released in 2010 and i just installed the latest F7 which was released in 2011. I don't think there's gonna be any difference.

that was it, i placed a newer psu i had for the living room pc, and even though it is 500w , for the last 2 days it works fine with no reboots. So thank you very much!
