OMG you think fixya is HP, sorry we are not, not by a million miles.
why should I?
this is old pc 6 years or less. and is fully out of warranty.
why would you expect free fixes, on any thing out of warranty
your car, your home, your TV or puter.
we can point you to a real HP page, we are NOT HP
this is chat room full of wild kids that love to guess.
there are 5 CQ62-100 to 400 and a00. we cant guess that either.
try here. one post on pink.
my guess its running windows 7, right? cant guess that either.
or did you upgrade to 10, oops, that kills many things dead. ask.
reload your graphic driver, here.
this PC had 2 choices new, one is Intel HD chip and other is AMD.
so one driver will load
and if not the other will
HP driver ,ran,tell you this in REAL TIME at load.
the drivers are exe files and they all check first if you have the matching chips or aborts and tells you , wrong driver.
we dont know the history of any PC.
if you installed a Microsoft windows disk , many things will fail.,
use only HP media to install. and win.
