Bugcheck 101 is caused by the CPU became hung and not responsive to clock interrupts. It could be due to overheating, overclocking, a BIOS bug, faulty CPU or in some cases driver bugs. The irony is the dumps won't give us any clues about the possible reason. So we should check for the possibilities one by one manually.
Everything except replacing thermal paste can be done without opening the case.
> To update the BIOS, use EZFlash tool which is embedded in the motherboard firmware. The official user guide contains detailed step by step guide. A printed copy will be available with every retail pack and PDF version can be downloaded at any time from their site. Refer the link i posted before.
> To monitor the temperature, use a tool like Core Temp which will show us the CPU thermal status from Windows.
> Another thing to check is the compatibility between the motherboard and the memory modules used. An incompatible module can cause various issues. This can be verified by referring the Qualified Vendor List published by Asus.
> Entering the BIOS and loading optimized defaults will clear any accidental frequency or voltage changes.
> A vanilla Win 7 install will rule out any possible driver issues. That is re-install Windows 7 from scratch and run the system without installing any drivers or software. If it is stable, add the drivers one by one and check if any of them cause the crash.
BTW, a failing CPU is the most common reason behind this specific stop error.
