problem with laptop memory

[aluminex]

I can't make heads or tails of this one...

I have a dv5z-1000 laptop and up until about 2 weeks ago it was all running okay.

Long story short... I thought the problem was heat and it probably was part of the issue. I have replaced the thermal pad on the cpu with grease and made a shim for the gpu and also added grease to it.

Anyway. The laptop won't boot if I have both sticks of memory in it. I can put each stick of memory in the laptop by themselves and it boots. However, as soon as I put both sticks in the problems starts...

I have had the same memory for over a year with no problems and I don't know what to try next.


Any ideas?

Have you run memtest86 on the ram? Maybe one of the chips has gone bad, or maybe one of the slots is bad?

This won't fix if there's a RAM problem, and you may already have done this seeing as you've replaced the thermal grease and such, but did you clean out the heatsink fins really well? Just a thought...

if you can find the CMOS battery try a CMOS reset.
