Didnt want to post this but got a few issues... since the new build been having random restart. Sometimes on forums , other in games others when idle and mining on usb miner. Any idea's? Sabertooth 990FFX AMD 9590 MSI Gtx 770 Hiper Type R2 770w Psu
personally I would be looking at the ram. I've had these issues before and it was either a duff module or the ram wasn't fast enough.
Don't know if this will help, but I once had this on my laptop, Was when playing wow mainly, from what I figured the onboard graphics had no limiter and tried its best to go as far as poss and overheated itself always crashing and normally restarting the PC, I used software that came with the pc and kept it on a profile that limited it capability massively in the end, still on it 3 years later
Is it freezing up or bsoding before it restarts? Try setting max performance with default settings in the power management options.
Just to check - you haven't manually volted your ram, have you? I know I've asked you that before but it's the main culprit on 990FX Asus boards when they're not behaving. Are you overclocked? try loading optmised defaults and see if it still happens.
ram manually set to 1.65v as it defaults to lower and that's the spec for 2133 / 10/12/12/31 is there anyway to shut off the dynamic clocking? seems to be at 5126mhz when I last booted!
You have most likely left Turbo Core on ( thats its name in the bios) whilst overclocking the chip and the chip will auto shut down once the temps hit a certain point. Which would be the black screen then reboot. Not every bios supports the disabling of this feature.( some boards you will not be able to acces it for example) Only other things to look for would be the PSU ( if you have another its a easy test) I would also take alook at your graphics drivers if this is a recent update to them you could try rerolling them back.
My build used to freeze (can't remember precisely if it black screen/restarted but pretty sure it went through that phase at some point) and it was always the RAM, try overvolting/underspeeding (is that a word?) the RAM even below it's rated spec and see if that does anything. Heavy overnight memtest runs didn't turn anything up for me.
