I am getting hangs / monitor goes black / auto restart and sometimes BSOD quite frequently.
Sometimes after it hangs, it will not even go into start up sequence and there was once where I switched off the power supply and switched it back on, the screen remained was it was when it hanged.
I install windows again, update drivers
but nothing changed.
Here are my minidump files and desktop specs.
Windows 7 Ultimate 64bit
i7 dell studio 1557 1.60GHz
