HP Lockups :: Envy 15 With Windows 8.1 - Fans And CD Drive Not Working

I have a 2012 envy 15 with Win8.1 Update 1 and a few days ago, i noticed that there was a newer version of my graphics card so I decided to update it.
 
After the installation, the computer screen became black and I only was able to see the mouse pointer, So i waited for almost half hour and then decided to turn of my computer. I restarted it and it kept seeing a black screen (the windows logo appeared during the boot).
 
As I couldn't do anything with my computer, I decided to Refresh it in hope that it will return to a good state. During the refreshing the pc restarted but the power light started blinking , like the computer was at Sleep, and when the refresh finished, the screen was good, but the light kept blinking.
 
I tryed to shutdow the computer but when i turn it on again I didnt ear the Cd rom making the usual noise and the lights where blinking. 
 
So i decided to maybe put it in sleep, but when i tried it, the computer screen when black for a few seconds and the pc went  wake immediately, and when i try to put it to sleep again, the Sleep option was gone.
 
Then I thought that something went wrong with  the refresh , so i clean install windows from a bootale usb drive since the CD wasn't working..
 
But that didn't work either, and to make things worst all my computer fans stopped working. So now I end up with a pc with a clean win8 install, the power lights keep blinking (both power button and the side light), no ability the sleep the computer, no cd drive and no fans..
