I tried to locate a bios upgrade for this pc but cant seem to find one, I have tried both the hp web sight for this pc and the motherboard websight both show no bios upgrade options, I did try just installing one of the new ram sticks in the machine at a time that was 4 - 2gb sticks and rebooted the machine with each stick by itself and the machine booted and ran fine with all.
what I have in th epc now is thre of the new 2gb cheap rams and one of the 2gb old rams sticks for a total of 8 gb and the machine shows 8 and I have not had any blue screens, I don't no what the deal is but I figure if I put that fourth cheap 2gb ram in with the other three it might start acting up again.
but it does seem to be issues with bios and ram settings im sure, but I am not an expert at anything concerning pc's just what makes since at this point.
it's running great now and thats fine with me while I am building a new up to date gaming rig so to speak. I have no answers for the phenomenon!
