After GTX 670 install, random restarts of computer

10 Year old computer:
Q6600, stock settings (No OC)
EVGA 680i SLI mobo
6 GB Ram
650 Watt Thermaltake Toughpower PSU


Infrequent restarts. My computer would be in the middle of a random thing, then it'll suddenly restart.

I recently replaced my HD 4870 with a GTX 670 (both uses twin 6pin connectors), and I've been getting more of these restarts.

I'm pretty sure they're BSOD of some sort, but even though I disabled auto restart in windows 10, how the machine would hang is first the screen will lose signal, and it'll stay like that for like 4 minutes before the machine restarts...

Is it my graphics card? Or something else, because this happened (restarts) even before I installed the new card.

Tried running Memtest86+, but it shows no errors (so it's not ram).
My motherboard has a vdroop.

Thanks!

I don't have any to borrow =/ And I don't want to spend $60-$80 on a decent quality one...
Are there any other diagnostics I can perform first before I have to buy anything?

I did, clean install of windows 10 about a month before I installed the video card. Should I do it one more time? Could it be a driver conflict?

My computer is able to stay on overnight sometimes and be fine. Other times when I'm on the computer multitasking, it'll hang up, screen goes black and loses signal, but the tower won't restart until after 4-5 minutes later by itself.

I ordered and installed a 520W seasonic PSU. Still random restarts. Installed my old HD 4870 and no more restarts...

Seems like it's my Graphics Card?

At least now with the PSU I can OC stablely...
