Guys
I really need some help with my system...

i m using P7P55 EVO + i5-750 aircooled with MegaShadow.
Vengeance 1600 RAM 8GB.
I manage to OC until 3.4GHz.
running all the test and all is ok.
Even playing games there's no problem.
But when leaving it idle...sometimes even for a short time...
it will get a BlueScreen error.

Ive used the OC'ers error code guide and do the suggested, it still happens.

Currently running at 3.46GHz@1.28v.

Usually the error will be 1e. 124 or 101. Sometimes the code is not even in the list!

Help plz?
