If it's graphics card, bring it down to the distributor for them
to see if it's working.
If it's still under 1 year, it's probably still under
warranty.
FYI, graphics card burn very fast. My first one lasted less than 1
year, fortunately it was under warranty then. I sent it for
repairs, when I got it back I gave it to my cousin. He finally
damaged it under 4 months.
