not necessarily frog.... the error message relates to the 2nd or more stick of ram...

as alarm has said he has 4 * 512mbs

up to 512mbs of ram usage there shudnt be a problem.. only after he goes over the 512mb limit and starts using another stick.. then there is a problem...

so...

the bios shud be ok cos it dosent use 512mbs to run...

when he starts using a memory intensive program and the threshold of 512 is reached then the bsod appears...


however im not sure why he gets the IRQL_NOT_LESS_OR_EQUAL msg

as all the ram sticks are the same

he should only be getting this if say for eg:

slot 1 has a 512mb

and

slot 3 has a 1gb stick...

now that shud result in a IRQL_NOT_LESS_OR_EQUAL.

but also @ alarm..

until you post the exact message (which includes all those 0's) then we cant help more specifically
