Hi,

8 weeks ago my HP Pavilion laptop crashed. The screen was blank.
Once I attached the laptop to my desktop monitor I saw that the error was caused by NVLDDMKM.SYS.

It was 3 month out of warranty.

I have discussed this with NVIDIA support - the graphics card is a GeForce 7600 Go - and they were no practical help.

I have discussed this with HP support and they have offered lots of suggestions;
Update graphics driver - Done same failure
Update BIOS - Done same failure
Update Chipset - Failed as updater stated latest version installed.

I tried system restore. This failed
I have tried both inbuilt recovery and HP separately purchased recovery disks. Both failed with a failure to read memory.

Reading the web this appears to be a relatively widespread issue with NVIDIA and Vista.

I can run in safe mode or I can run in Windows without the graphics driver.

My machine has Vista home Edition 32 bit @ SP1.

I cannot think of what else to try>

Any Ideas?

Questions:
1. Is there an ATI card which would fit the HP Pavilion dv9385ea?
2. Should I reformat the hard drives and install XP Home?

Thanks,
Mike

I vote, yes!

My reasoning being that you've been messing with a 64-bit system file, I'd just reinstall it would save you the trouble of trying to fix it manually. Good luck.

It turns out that the BSoD is one of the many symptoms related to the NVIDIA graphics chip which is known to be faulty. No known repair (replacement mobos seemingly have same chip therefore same flaw. Overheating problem apparently.
