Having problems with your HP Pavilion A6400f Desktop PC, Refurbished ?

Monitor shows VGA no input signal DVI no input signal then monito going to sleep


Answers :

This can happen
1.when your display cable have problem
2.video card may have problem

you can
1. check with different monitor to confirm that the problem with display cable or videocard
2. if you find out display cable problem then take both monitor and display cable to solve this problem
3.otherwise you can try to remove graphics card and clean insert it again(if you have installed graphics card seperately)
4.in case if it is on board you can try to buy a new graphics card
This sounds like a video card driver issue or the card it self. Make sure all cables are plugged in snug. Once done try to boot in to safe mode by restarting the computer and while it is starting keep on tapping key F8 and choose safe mode. If this works it is driver issue. If nothing happens it is the card it self. Might have to take it to a authorized repair shop. Hope this helps.
