O.K so having just completed watercooling my cpu and gpu, my machine has started to randomly crash.
Well what actually happens is the monitor goes to sleep, and the pc stops responding, does not shut down/reboot.
It does not seem follow any pattern, runs fine through prime, furmark, games etc with good temps on idle and load (using realtemp and EVGA precision and Everest) on CPU, GPU and GPU memory and pcb.
CPU idle low 40's and load mid to high 50's
GPU's idle at 37c and load low to mid 50's
Started to happen 10 days ago.
On Thursday just gone I had some time off and had the PC running all day, and it crashed 3 or 4 times again no pattern ( 1 was gaming, 1 was internet, 1 was idle)
On Friday when I booted in up I went into the bios, it flashed a message up saying something about the overclock was causing problems and it reverted to its backup of stock settings so I left it and it seemed to run OK,(it had previously run well @ 4ghz for a year with no problems)
On Saturday morning I upped the overclock to 3.5ghz and it ran fine until 10.35pm whilst I was watching the TV in the other room and the PC was idleing with a screensaver on and it crashed again.
On Sunday it ran fine until I moved the mouse to turn the screensaver of to use the internet and it happened again.
It started happening just after I watercooled my GPU's, so I took them apart thinking there was a problem with the thermal paste/pads. re-applied new paste and pads and reassembled. Still randomly crashing.
Have tried swapping gpu's round, turning off sli, etc. Still randomly crashing. (don't have access to a spare GPU to see if its that)
Has anybody experience anything similar? or can offer any advice?
Would be most grateful for any thoughts, it has left me scratching my head!
Many Thanks for bearing with me through my ramblings.
