Wtf...just happened?

I just got my computer repaired today after weeks of waiting. Was installing amd drivers for graphics card and BOOM...just shuts off. hit on button and went into continuous cycle. shut it off and tried to turn on but now it wont he turn on. wtf just happened?

Gunna need some more info other than "BOOM"

Is it a pre-built machine?

Does the machine even post? Are there any beeps at boot?

Why was it being repaired in the first place?

Possibility of an overheating problem after the fix and/or OS bugs.


That sounds like overheating to me. 

Fixed it. For some reason the psu main cable is sensitive and comes out if you barely move the pc.
