Vista - Why does my new Laptop do this?

New HP dv2000 laptop:
Vista 64bit Ultimate SP1
Intel Core 2 Duo CPU T9300@2.5 GHz
Nvidia GeForce 8400M GS
4 GB RAM

This Laptop has been in service since 25 June 2008

The screen in the picture below has shown up twice. Once upon awakening from sleep and once while reading a document in Firefox.

The only cure is to press and hold the on/off button until the system powers down.

Windows says that I have the most current video driver.

What else can I check before sending it back to HP?

Just send it back, that's got to be a hardware fault.

Thanks, guess I'll see how good HP is at returns.

OHHHHHH...I saw that on my HP laptop also....perty colors. Sent back and they replaced MB (integrated vid card). Was a DV9500CTO, 6 months old. Had it back with a new MB within a week

maybe you could go to the hp site of ur country and install new graphics drivers i know when i got mine i would get a white screen and black lines every so oftern and i updated my graphics drivers and it fixed it. i called hp and thats wot they told me to do and to update my bios.
