Hey everyone,

It seems that i hava a boot problem about my windows 8 64 bit Pro which has just been installed on Hp laptop about 2-3 weeks ago. After the installation of windows 8, I updated my AMD Southbridge driver via "drivergenius" and also installed an Advanced System Optimizer-IObit ASC, which can not only quick and extensive clean up your computer but also can speeds up your pc performance and internet access. but when i restart my pc and running the program, i was confronted a blue screen which has just last about 2 seconds. so i can't see clearly what it says.

i have run the system recovery option several times but this phenomenon still existed.

does anyone know what could be causing this?

any hints would be greatly appreciated. if you can come up a fix for it is much better.
