Computer crashing. Reason unknown.


Ok so my computer has randomly started crashing the last few days. It will be fine, i played guild wars 2 for about 12 hours last night, however the night before after an hour or two playing it crashed and wouldn't start up again and today again it launched from standby fine and launched guild wars 2 but then suddenly crashed and now struggles too boot up.

When it crashes the screen goes 'frazzled' like an out of tune TV but frozen and teh sound sticks. Sometimes it will go to a blue screen talking about 'recently installed hardware/software' causing the issue. It then either wont boot (when the power button is pressed the screens come on but blank and all that happens is the GPU fan spins up and down repeatedly until you turn the box off at the power supply) or it boots up only to crash instantly in the same way...OR...after a while (and removing all components blowing then in a way that should fix everything!) it will boot up and work fine.

I have absolutely no idea what to do to isolate the problem. Could it be software? is it worth going to all the hastle of a reinstall? I wouldn't have thought that would work since its actually failing to boot at times? How can I isolate what hardware is broken if thats the problem?

Any help would be greatly appreciated, as you can imagine iv been prepping for GW2 for months and just as i can play it the computer breaks. -_-

  1. Update:

    After spending an hour or so trying to figure it out and many unseccesful reboots i made the above post, about 30 minutes later i tried the comptuer again, it worked fine and i watched 2 episodes of lost on it before going to bed...

    I'd really like to isolate this problem! Any ideas?!
  2. Bump!
  3. Bump... :(
  4. Have you recently added any hardware that could be causing the problem?

    Best suggestion would be to breadboard the system, go back to the basics, and add components only if your previous stage worked as intended until you find the piece at fault.
