What about temps is it overheating, heatsink has new thermal past and seated well?

random pc reboots..........i get these time to time???????? dunno why?

If your running xp then there is a setting to stop it rebooting, instead it gives you the blue screen of death. Usually this gives you info on what might be the problem.

 

To stop it rebooting:

Right click on my computer, go to properties and click the advanced tab. Under start up and recovery click settings, then unmark the box with automatically restart.

Its vista..

 

Like i said in the pm, reformat!

 

Or try the boot cd that beermoster said, thats an amazing tool!!!

i'm running xp

 

it just randomly reboots at will...

 

the reboots are less frequent now...

 

but does happen here and there

Prob a software issue

any suggestions?

I had the dreaded blue death screen......everytime when windows was booting it would crash half way through........ive had to reformat everything and reinstall windows.....seems ok at the moment,,runs alot quicker,most prob because ive got rid of all the shit that was on my hard drives....

Reboots are rarely random, as mentioned above check cpu temp and do a thorough memory check using one of the utilities like MemTest.

i think this is due to some :hurl:MICROSOFT updates...it happened to a few of my mate's... they ended up turning auto updates off...has been fine since!

Microsoft updates or a virus, there was a virus around a while ago that did it

the only time i have had this (twice) it was ram i had 2 sticks and one failed giving me the blue screen, it is usually hardware failure that gives this screen. my new build also gave me this problem from new again one stick of ram was faulty. take one out and try it then swop if it does do it just to rule this out

it was reformatted just after fitting the mobo that was first port of call it restarted even when reinstalling windows. I'll try the ultimate boot cd see how that fares i have a spare new sata drive to try too

cheers all

the shop i bought mobo from has had it running for over 4 hrs without a sigle reboot. So now I need to start looking at the keyboard/mouse(brand new xmas pressie...hmmmmm) surge protector router all cables and monitor.

i doubt very much that any of those would cause it to reboot.

I have few other option to look at now

i rigged it up and guess what .......it restarted twice wouldn't even boot. I have changed the dvi connector to the other port and it started so I will leave it on for a bit and see what happens

hi mate . i wouldnt mess about with the cpu core voltage , best left as it should be :shock:

core volt is stock 1.24v as here http://www.300zx.co.uk/forums/attachment.php?attachmentid=45822&d=1231679949 ... but will take on the box max 1.35v(have read they will take 1.6v!!!! :eek:) I increased it slightly to see if it would stablise it, did not help so set it back to stock.

 

my ram boots on auto at 1.8v on both my asus boards ,corsairs stock volts for these is 1.9v when I built my last rig 2gb was stable at 1.8v and worked for months put 2gb more of same in and I had to up the voltage.
