Hi! I have two GPUs (Gt 630 4gb MSI and GTX 1080 Ti Lightning X). Both crash at any moment doesn't matter if I am able to boot and run a benchmark or if it's while booting. At times GT 630 fans don't spin unless I pull it out and put it back in while the pc is powered on (with no display), if I reboot the fans stop spinning and it doesn't work. Now I am thinking that this is a mobo issue. I went to a pc shop and the GPU (GTX 1080 Ti) worked till he ran furmark with my PSU because he didn't have one with 3 pcie 8 pin connectors. Yesterday the GPU worked for about 6 hours before crashing and to get the display out of it and get it back up and running I have to reset bios every time. On board graphics work. I would really appreciate any help as to determine if it's the power supply or the mobo causing the issue.
