have you overclocked? if so it may just be some unstable clocks
is anything overheating? NB temps? cpu temps?

Nah, i havent OC'ed and plus i dont think that i have any high temps anywhere in my pc :\.. except on HW it says TMPIN2 is 78 :S but ive asked about that on another thread and i suspect it is a bogus temp... sooo im kinda stuck here

There are a few possibilities. First of all, was it ever stable, or is this a new build that has always had this problem? Is it overclocked at all?

Try and reset bios defaults and see if it fixes the issue. If not, check your temperatures. It could be overheating and shutting itself off. If neither of these seems to be the cause, I'd suspect the RAM. Run memtest overnight and see if it turns up any errors. After that..move on to the PSU..etc. There are a lot of reasons this could be happening. That should give you a decent starting point for troubleshooting.

yeh.. i suppose so, i went to system properties > advanced settings > settings on startup and recovery and also unchecked the Automatically restart box.. so i'll see if i have anymore problems that may occur later on.

Your heatsink is probably not seated properly on the cpu, causing it to overheat, try reapplying the heatsink and cpu, and use a program to check your temps.

No need to stress test since he said it just restarts randomly when he boots up his computer. Those idle temps look fine though, might be an issue with the motherboard then.

didnt see it mentioned above though i may have missed it.. did you check your event logs? for errors around the times the reboots happen?

I would have said it sounds like over heating too... have you actually watched the temps from boot till failure?

If you did a clean install did you make sure your chipset drivers were updated along with all the other hardware drivers? Also, flash the BIOS as others have recommened and make sure the RAM values are correctly set in the BIOS.

Make sure everything is completely seated ie RAM sticks, 24pin line on mainboard etc..

Just out of curiosity, why did you change mainboards? Were you having issues that led you to change boards? I only ask because if you were then it may have been something else like the PSU...

Guyssss :( My pc is still restarting.. Ive updated the bios, i dont know what to do now =\ and when i start up the pc .. after the bios screen it says Updating data pool .. update succesfull :S

Im confused again

Could it be that because one of my sensors on the motherboard are messed up, and reads false temps (because it does), as shown on one of my other post TMPIN2 idles around 78 :S and is always at 78. And it might go up sometimes to 80.. and in my bios my CPU failure warning is set at 80 degrees :S I dont know :(
