RAndom restarting

[quadraspleen]

Hey all,

In the last two months my RIVe has been randomly just rebooting. No warning, no overheat. No over-voltage. It just restarts and goes through a standard restart routine. Nothing in Windows event logs except "the last system reboot at was unexpected."

I've done the following to troubleshoot:

1. Un-clocked it.
2. Removed both power and reset headers from mobo and used the power switch on board to turn the machine on and off.
3. Changed/replaced the power button assembly in my CoolerMaster case.

Nothing seems to work. Some days if I leave it on while I'm work, it will only do it once a day, sometimes if I am heavily using it, it does it three or four times in half an hour (grrr) and then "stabilises" (though that could be a placebo from me)

Is it borked?

Thanks

Well it could be a whole host of things...but a chief suspect would be RAM....followed by drivers crashing on down to faulty SATA cable...SSD firmware out of date....

Is that one kit of RAM? set up with XMP or manually?

Jake could be so many possible causes.


Could you tell me how you know for sure there is no overheating please?

Thanks for the replies guys,

ok, Arne: it's one 16Gb kit of RAM set up with either XMP or manually; it seems to make no difference, but when I use XMP I get weird timings on my FSB, as noted in an earlier post, so I tend to stick with manual. I can try all sorts of you think it will help. Would a faulty SATA cable etc cause this?

HiVIzMan: I'm using RealTempGT with history turned on. Even at 4.6Ghz under full load my CPU temp never rises above 58deg. My mobo temp seems to hover around 45deg (as noted by various apps). I don't think these temps are too bad, do you?

Thanks again guys

How are you setting up the RAM .....what DIGI+ settings etc....have you followed HiVizMan's Memtest 86+ guide to test the RAM?

Any BIOS updates driver updates etc. that coincide with this?

No BSODs just straight power off and restart?

[quadraspleen]

Sorry, I said I was using manual RAM settings in my second post; this is not correct; as per my last post, they are at auto

Hi Arne,
1. The RAM I am leaving at stock settings (auto)
2. DIGI+ all I have changed is to set it to OPTIMIZED and MEDIUM HIGH for LLC,
3. I have MEMTESTed the RAM but not since this issue; I will test again tonight.
4. It did seem to coincide with a BIOS update and my last post regarding the funny FSB speed reporting, which I think you helped to answer. But having said that, I think it happened a bit after that.
5. No BSODs or anything; it's as if someone has hit the reset button (hence my removing both the start and reset headers from mobo to test.

Thanks!

Have you investigated what the event viewer suggests the cause is.

[scotland21]

Did you update both bios chips, if not I would suggest switching to the other bios chip in case you got a bad flash.

[quadraspleen]

HiVizMan: the event viewer says the last system shutdown at was unexpected. No errors prior to the event whatsoever. This was my first port of call. NO errors at all in either syslog nor applog

scotland21: good idea; I'll try that.
