Presario 734EA - Memory upgrade problem

Hi all.

I have a Compaq Presario 734EA with 256Mb of ram. I recently bought an extra
256Mb module that was installed whitout problems. The computer ran smoothly
for a couple of hours and then it simply froze... I have tried to reinstall
Windows XP Home, but it dosn't help. The strange part is that sometimes it
takes 20 min before freezing sometimes 8 hours...

Does anybody have a clue why this happens and what i should do to prevent
it?

Some 700 series notebooks have had heat-related lockups. Does the fan speed
up just prior to the lockups? Oh, the 734RS (Radio Shack) model is only
upgradeable to 384MB. I don't have specific info on the EA (European) model,
however.
