yes my new unopened HDX 18 has a nvidia GeForce 9600m GT graphics card , now im really worried!!Message Edited by Toronto699 on 11-20-2008 06:09 AM
I do not know how to advise you except use-not abuse-- your computer to the max during the warranty period and if you are so inclined game the heck out of the GPU, as many young people do anyway.
Here is some information that might demonstrate that even the newer NVIDIA 9000 series GPUs are susceptible to the failure:
"A little digging revealed what this, and more, is all about, and it's far uglier than just the 'notebook' version. It seems that four board partners are seeing G92 and G94 chips going bad in the field at high rates.
Well, the G92 chip is used in the 8800GT, 8800GTS, 8800GS, several mobile flavours of 8800, most of the 9800 suffixes, and a few 9600 variants just to confuse buyers. The G94 is basically only the 9600GT. Basically we are told all G92 and G94 variants are susceptible to the same problem - basically they are all defective. Any guesses as to how much this is going to cost?
From the look of it, all G8x variants other than the G80, and all G9x variants are defective, but we have only been able to get people to comment directly on the G84, G86, G92 and G94, and all variants thereof. Since Nvidia is not acknowledging the obvious G84 and G86 problems, don't look for much word on this new set either - if they can bury it, it will drop their costs."

yes it does seem you have a nVidia GPU/chipset that's overheating. The driver only enables features and higher performance, you are still using the same video, same chip, it's not actually disabled as it is still processing and outputting the video so if it totally fails you will no longer have any use of the laptop. If it seems stable enough to take a chance, see if there's a newer bios you can flash to it which may increase fan speed, reducing heat.
We can't predict if it'll keep working for 4 days. It might run like that for a year or fail in the next hour(s). Probably the latter is a closer estimate since you've already seen some symptoms but even if you shipped it off to HP for servicing you wouldn't get it back within 4 days from now, especially considering it's the weekend.

If you hook-up an external monitor and can get into Windows try disabling the video driver. I actually removed it (the Nvidia driver). Restart the computer in VGA (640 X 480) with like 8 colors. You can then access your files. The screen looks really bad, but it works on mine.
Windows running without the video driver will still allow resolutions higher than 640x480 and more than 8 colors. That was a limitation only on (cant remember which OS for certain but not WinXP or Vista) Win2k or Win9x and older. Without the video driver the resolution and color depth can be increased in Display Properties, it just won't go as high as it did previously, and may be limited to 4:3 ratios instead of widescreen 16:10 ratios.

It is the only resolution that will work, it is not selectable, at 4 bit, 640 X 480. With an external monitor, the only way it will work, I still have vertical green lines across the screen. It is readable. I believe it is the last dying gasp of the NVidia chip on the motherboard.Interesting, normally that VGAsave driver is just the default when the OS is installed and there's no other driver windows can find (nor is installed) and allows 800x600 and 1024x768.

I chatted with an HP tech and after explaining the problem, she said to load the nvidia driver from the recovery disk. Instead, I went to the support site and downloaded the oldest driver listed. I also found this post (very bottom) about disabling the Transient Multimon Manager (TMM) and did that at the same time.
I don't know if it's one or both that made a difference but if this solves it, I'm going to be happy, even though I followed so many suggestions that I'm going to do a full recovery just to make sure everything is back to normal.
