My graphic card sometimes won't start up, HELP

[PrimZ666]

so let's to the point, i have zotac gtx 1050 ti oc, these are the point of my problem.

• 
  graphic card doesn't start but the pc does and onboard graphic are working as well.

• 
  last time it had a same problem but i disassemble it then clean it using a soft brush and it worked, but next time i use a same method it won't start up again.

• 
  its like my graphic card doesn't receive any electricity from my motherboard

any idea??

It would have been easier if you listed your specs but ok This could be a problem with your pcie x16 slot not working which would explain how your cpu and other components receive power and work but your gpu doesn't in that case you would probably have to get a new motherboard the problem may also lay with Graphic card and if it does best to Rma it if still in warranty and the final problem that you may possibly facing is with the PSU which wouldn't make much sense because most PSU problems I've seen make the whole computer reboot but that doesn't mean its not a possibility
