I've been experiencing serious issues with my desktop in the past few days, the problem has been initially intermittent with the odd crash and stall but seemed to work out fine after the classic turning it off and on again.
Then i started to get the blue screen of death after having installed Skype on the desktop (I only used the desktop for games at first without any browsing or other software being installed due to the limited space provided by the solid state drive.) If I launched Skype I would immediately get this screen : + Show Spoiler +

I tried re-installing it several times but each time as soon as I would attempt to log in the same message occurred, personally i thought i could live without Skype no big deal. but after crashing in the middle of D3 i tried restarting the computer i got a black screen with the mouse cursor after the loading welcome message. Occasionally after a long time it starts up and works, but crashes within several hours, it starts loading for too long then i get this:+ Show Spoiler +
