Hi everyone.First post here so bear with me.
So a week ago i was played like 2 matches of league of legends then go to sleep.Next morn i go to work and when i come home,since a do some computer service in my spare time, a neighbor asked if i have time to take a look at his compute since he couldn't set up the internet connection.I plug his computer in no drivers.Figured i download them from my computer then put the drivers in his with a usb drive.
And now to the problem...
My computer didn't wanted to display image.Looked fast at it and it displayed image with an old 8400gs lying around.After setting the computer for the guy i looked at mine and managed to get 2 display from my gpu until it died completly,since it dosen't even get hot now.
So my question is what can cause a completly fine video card failing overnight?
Sorry for the wall of text :D.
 
Solution
any electronic just dies due to its age, usage, heat,, manufacturing faults, bad soldering, cheap components....

also a bad power supply can reduce life span of the whole system

electostatic discharge while installing the hardware can pre damage electronics

mechanical shocks as well
