I have an HP Pavilion a1023c (Product # PW7100AA) running XP Home Edition bout several years ago from Costco.
Two weeks ago it fell down but worked fine. Now every time I turn it on, the monitor displays the following information.
Monitor Status - VGA Input: No Input Signal.
Ten (10) seconds later, it displays "Monitor going to sleep".
I tested the monitor using a friend's computer and the monitor works fine.
I opened up the computer and cleaned dust off the fans.
However, the same message still shows up.
Because it fell, I'm inclined to think it's a simple hardware problem.
A little research indicates it could be the graphics card but the internal hardware pictures
I have seen online doesn't look like my computer so I can't identify it to attempt a replacement..
Any help would be appreciated.
Thanks in advance.
