Help, my DV9000z is slowly dying!!

Hey all,
Since a couple of weeks my grandparents DV9000z is crashing at random moments. Two things occur. 1 I get the blue screen saying windows has shut down. 2 the computer just freezes.
Does anyone has a similar problem or knows what to do?
I have done the following, updating many drivers, scanned for viruses and malware many times. I am actually thinking of using the recovery disc, because I am out of ideas.
Here are some details of the laptop:
Vista ultimate 64-bit
AMD turion 64x2 1.60GHZ
2.0GB RAM

Any help is welcome.

 

Check if your notebook is in this defective list

 

It is not on the list.
The laptop has been working for over a year without any problems. So my intial guess was that it is probably a bad update or something. The only program that was installed in the last 2 months is the Avast free virusscanner

 

All HP notebooks from that generation with NVIDIA chips are defective but HP's list is incomplete. I'm with flipfire, your notebook's northbridge chip is probably in the process of failing especially if you never flashed in the BIOS update that runs the fan 24x7.

However, just to be thorough, you could try running MemTest86+ for at least half an hour and see if it flags any memory errors. If it does, test each SODIMM individually. Bad memory will drive you crazy until it's diagnosed. Clean installing Windows is also an option.

Run the HD test that's in the BIOS too, after you've backed up any important data.

 

Dude go to event viewer in administrative tools and see if you have an entry after one of these events. I'm guessing this should give you a better idea what is happening without jumping to conclusions.
