I have never had a puter loose RAM before. Its a Dell latitude CPX notebook P3, 128 megs ram, 10 gig HD Was happily surfing away. Everything froze up. Then the dreaded blue screen of death showed up and said that the thing did a mind dump. Rebooted and got the "memory had changed " message Hit F2 and saw I had only 64 megs of Ram( should have said 128) Shut down Poped off the memory cover pulled out the modules and put them back in. Rebooted. Everything back to normal. 128 megs ram. Put The machine back on line and gave it a work out. Same thing happend again. slowed down, Froze, Mind dump. I figgure I lost a 64meg module. So is it time to upgrade to 256 megs? Or i was wondering if anything else could be wrong? Are the memory modules kinda like the Dist modules in GM HEI ? I guess When they get hot it just starts running bad or stalls. Thanks for any help.
