Question about HP Pavilion a420n PC Desktop
My computer was working well. The last last thing i remembered is that the computer downloaded WINDOWS AUTOMATIC UPDATES. I dont know if it was installed properly by my little sister when she turned it off. Next day after, when we turn the PC on, the monitor will only show streaks and dots of different colors. What is possibly damaged here?
If it is doing it to the start up screen(hp) it is probably the display chip on the motherboard (you may be able to clear this up by removing the battery from the motherboard and clearing bios( connecting the two pins on the motherboard.
But before you do this check your video output with another tv monitor

The problem is the update you downloaded someone mixed with your graphic chip.. causeing it to only display dots and lines. the hp logo with the back round is the start up page. here are 2 ideas you might wanna try.
1. if your graphics car is in a AGP or PCI, pull it out and try useing the default card build in the computer.. if it is the default go out and bye a cheap graphics card and see if that works.. if not return it and get your money back.
2. try useing a diffrent moniter.. your moniter might of blown out. if that still dont fix it you might need to contact HP or the moniters manufactuer.
hope this helped!
