Any flags in device manager? In bios is there a hardware monitor, if
so check the temps, and voltages, might be a failing power supply.
Find out who made the hdd,,go to makers website, download and run
diagnostic on drive..Still could be ram, run memtest, free download
do a google, run test with one stick at a time.....
Also while in bios make sure usb 2.0 is turned on, check all options for
usb, something may not be working to its full potential...
Write down what errors the bluc screen is showing, usually at the end
of all the numbers there will be something we can understand, ie,
nv.dll stopped, ati.dll, system32halted, etc...
