Hi,

After I experienced some shutdowns again. I decided to do the final
test. I went to the website you advised me, but there they did not say
anything against unequal memory sticks.

But I thought I understood it matters which stick is in which slot. So I
opened up my laptop and exchanged the memory sticks, so that the biggest
one is in the primary slot and the original 512 MB in the secondary
slot. And guess what...??? No problems whatsoever anymore......!!

Even with 1,2 Gigs RAM in use PS keeps running like hell.

I'm glad and hope I can somebody else with this information.

Best regards
Kees
