I have been having continuous problems with my PC crashing, restarting or giving me occasional BSODs. Recently the motherboard bios was stating power-surge warnings when rebooting, so I have since replaced my PSU. The power surge warning has gone, but the 41's and freezing persists.
My system is a Asus X99 Pro, 5960K, GTX Titan X SLI, 16Gb 2,666Mhz Corsair DDR4 RAM, Corsair HX1000i 1KW PSU (Old PSU is a AX860) 512GB NVMe Samsung 950 PRO.
I have quite a lot of experience building PCs, and would say my knowledge is average. This one has stumped me. So far I have:
Reinstalled Windows 10
Change/update/rolled back drivers
Bought a brand new high quality PSU
Used different power sockets
Updated the bios on the motherboard
Returned CPU/GPUs to stock speeds
Ran MEMTEST86 - passed
Ran Intel stress test - passed
Does anyone know what this problem is most likely to be? I am about to try reinstalling Windows 8.1 on a sata SSD and install new power cables through my PC. I have seen many other threads where people guess at it being PSU CPU RAM or motherboard, with no real evidence to suggest which one it may be. The PSU is not the issue.
Many thanks for any help.
