Partition problem

First let's get some information, with both RAM cards installed, download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

For posting the information , enter 'Snipping tool' in the Start button > Search box, hit enter. Select the area you want to post and save to a convenient place.

Take out the RAM card that won't run memtest86+ and see if you have any freezes.

I used CPU-Z 1.56

Don't see anything unusual in the CPUZ snips.

You can't adjust any setting in an OEM laptop, so there is not much you can do.

Can you arrange to test other PC2-4300 266MHz RAM in your computer or your RAM in another laptop?
It would probably cost more for a shop to test it then it would to buy new RAM and hope that solves the freezing.
A quick check on Newegg, 2 X 1GB DDR2 RAM is about $40.

Wish there was more we could do with it, only way to test it is as mentioned above.

The possibilities are RAM, motherboard RAM slots, motherboard NB-memory controller, power supply (not common for laptops), these are the most likely causes.

Out of these, RAM is the most likely culprit.

Doesn't sound good.

Let us know the results.

Thanks for the update, let us know how it's running.
