The only thing i could find in bios was
System temp: 32c
CPU temp: 32c
system fan speed: 3200rpm
CPU Fan: 0 rpm
Northbridge fan speed: 5900rpm i don't know if any of this helps but it's all i could find about temp, looked in all the options all i could really find about tempeture. never found it saying shut down when temp reaches.. this temp or nothing like that
Someone might have questioned this but I didn't see as I scanned through the pages. 0 RPM on the CPU fan could be bad in one of two ways - 1) you have a fan on there, just not using the mobo's plug, so you'll need to disable any sensors in the BIOS, or 2) the CPU fan is really ... dead. Either of those possible? The latter would explain your situation - as it's booting, it heats up quickly and shuts off.
