My system restarts no warning

[joshnz]

Hi everyone, my system in the last few weeks has developed a few issues.
#1. GPU fan needs to be replaced.
#2. Occasional BSOD and applications crashing.
#3. Sudden reboots no BSOD system log all clear.

Problem 1 working to get GPU replaced still under warranty.

Problem 2 ran memtest386 over night may have a stick bit

Problem 3 well I have to investigate seems like some 1 presses the reset button I don't have a clue where to find that source thinking ram or psu.

My system is in my sig.
any opinions ideas

Well I have noticed restart happens when I'm running vmware player but I think I remember it restarting another time when I was not running vmware.
Also I can play bf3 for 6+ hours no problem.

ASUS M4A89TD PRO USB3

My dad had one, it did the samething. It started crashing. I memtest it, it kept failing but test the ram in another rig it was fine. I RMA'd it 3 times but I still got the same board back, the third time they just removed the serial sticker and replaced it with another one, it still failed memtest.

The problem was the sideport memory, you can disable it in the bios and memtest again.

Re: My system restarts no warning

Thanks MP I'll disable it and see if it helps.
I used to love asus but if this board going to give me more head aches hmmm.

Re: My system restarts no warning

Do you know where the setting in the bios is?

[Mad_Professor]

Re: My system restarts no warning

it's under AI tweaker, "GFX overclocking" set it to disabled or if you need it set it to UMA.

Re: My system restarts no warning

Ah I can't find it due to my model does not have integrated graphics.

Re: My system restarts no warning

Well for now I have unpluged the reset switch.
It reset when I was in game.
also so you guys know all my machines have the automatically restart check box unchecked in startup and recovery also this restart happens in either of my win 7 machines
I will also use it in xp and see if xp can trigger it.

From what I have read it may be new mainboard time

If that is the case will it be fine to use same chipset this mb uses?

Re: My system restarts no warning

ok so far it still reset with front panel disconnected.
I have now reset bios to factory removed all unnecessary hardware.

Have you scanned for malware?
I don't think that's it but it's worth a shot...

Possibly.

Still reset with the extras removed.

Well at the moment i'm running with one core enabled.

old mb

maybe future new mb
http://www.gigabyte.co.nz/products/p...px?pid=3781#sp
and 1.5v ram x2 (gigabyte site says 1.5 my current ram is 1.65)

Re: My system restarts no warning

That sucks, I have the M4A89GTD PRO/USB3.

It sounds like lack of voltage somewhere, bump the volts a little and see what happens.

[joshnz]

Re: My system restarts no warning

OK bumped up the volts on all mb components and cpu nb.
hope it works.
What gets me is it can run fine for 6+ hour heavily loaded. and sometimes 30 mins with lite load, I would expect stress to trigger issue.

[joshnz]

Re: My system restarts no warning

7 hours looking promising.

[joshnz]

Re: My system restarts no warning

ok got back and it was hard locked so I reset it
It hard locked windows boot
powered it down then powered it back up and is working again.

[joshnz]

Re: My system restarts no warning

Turned on today reset it self during windows boot then again when I was using it.

Re: My system restarts no warning

One other thing you can try is using Kingston RAM. If that doesn't help, then it's probably the motherboard.

[shovenose]

Re: My system restarts no warning

IMO Corsair RAM is unreliable crap.
