Asus a8js problem. Help me diagnose.

Hi Everyone

when my laptop boots the second the screen turns on and it should display "ASUS" before the bios posts, it displays a white screen with many 1 pixel wide vertical lines of assorted colors. If I leave it on for a while the entire screen goes black.

It still plays the chime when it boots and the HDD light makes it look like its actually going through the boot process. After it boots, keyboard commands to shut it down are unresponsive.

Before this problem, my computer would be totally fine until I try to run it without AC power. First, various pixel dots would appear in place of icons, then the screen starts to blink on and off and trying to control anything becomes nearly impossible. I can open the start menu but thats about it. To stop this I would have to reboot with AC power.

My battery was totally fine when this happened.

Lowering screen resolution solved this problem and allowed me to run on battery no problem.

SO, that should be it for the symptoms and solutions I've tried. At first I thought it was a power supply problem, not providing the proper voltage to my video card. I have read through the forums here and see that a couple people have trouble with nvidia video cards, something about nvidia using bad materials. So I now think that could be the problem. If it is my video card only, I dont quite understand the symptom where it requires AC power.

 

This does sound like a problem with your GPU. You could try using an external display when you're on battery power, to rule out your LCD and its display cable. Is it overheating? The 7700 wasn't one of the cards that had underfill problems like the 8 series, but it could have gone bad for other reasons. It could also be a problem on the mainboard.

 

yes I forgot to mention that if I plug it into a monitor, it displays the same thing onto the monitor so i dont think its my lcd.

 

Sorry about that, there are a couple of shot-in-the-dark type things you could try, like clearing your CMOS/resetting BIOS to defaults, or getting a new battery, but those may lead you nowhere. I'm not positive since I never owned one, but if the A8Js has a discrete video card (not embedded on the motherboard), you could keep an eye out for a replacement. It all depends on how committed you are to that system.

 

hey thanks for the help!
