HP Pavillion DV9574ea Graphic Issue

Hi All,

When I power on my laptop, blue dots or blue lines appears on the screen. As soon windows vista boot screen comes, a multi color screen appears and it stays there until i restart. I have did all the troubleshooting such as memory modules replacement, factory restore, system recovery etc. but couldnt able to solve the issue.
When I go into safemode and remove the nvidia drivers, system starts working in 16bit color mode. I have installed several graphic drivers but then again multi color screen appears on windows boot screen.

As per my local repair shop, its an issue with integreated graphic chip and he can fix it by replacing it with another graphic chip. therefore no need to replace the board.

Is it possible to replace the chip ?? . please suggest.

Thanks
Alen

I would try 1st with an external monitor. It could be hopefully just a bad lcd. But if it is the GPU, I am afraid that you'll need the whole motherboard.

Check out the "baking" within NBF?

I confirm that it is not possible to just replace the GPU chip. NBF is where we are - Notebookforums :-)

And for "baking" - check out this thread:

If it is the same form I don't see why not. Pay attention to the LCD connector though, this is where I always got stumped in the past.
