By right you should copy down the error code and do a google
search online, there might be some people having the same problems
with you.
For me, in most BlueScreenOfDeath(BSOD) involving booting of the
system, i will start by troubleshooting the hardware.
When the computer starts, the 1st program that run is the BIOS.
During that time, the system will check the hardware installed.
Thus most of the time if the computer cant boot up till the windows
logo, it should be the hardware at fault.
Try to take out the RAM(s) installed in your computer.
If you have only 1 ram, rub the contact with an eraser, clean
off the dust, and put it back, if it cant work, find a working
spare one from friends or somewhere
.
If you have 2 or more rams, take both out, put them in one by
one and boot the computer. If one of them is faulty, the computer
wont start, take out that one, put in the 2nd ram, if it starts,
most likely the 1st ram if faulty, and tat could be the source of
the booting problems. If both ram cant work, put in a new working
ram and continue troubleshooting.
Lets say Even after putting in new ram, the problem still exist,
keep the working ram installed, try to change other components like
graphics card.
Most of the time if the comptuer doesnt boot after putting in
new ram, it could be that the ram slot is faulty.
IF you have no problems booting up, but BSOD while running
windows, it could be software or driver issues, however it doesnt
mean that your hardware is not faulty
