my instability problem is most likely caused by a hardware issue... Now my problem is which, and how to solve..
Most likely causes:
-Buy new memory (cheapest so first to try)
According to my MoBo manufacturer I can either get DDR2 SoDimm 533 or 667. Which should I get? Is there a big difference?
-Buy a new CPU... Ouch!!! (most likely not the case I understand)
-Get a different Power Supply (which might be a bit difficult for my casing... which was expensive, so hope the memory is the solution)
How can I best test these components to see where the problem is? And if I try the memory replacement (step 1) Which should I pick.
Thanks for the advice/tips
