Hi, I have a HP server with windows server 2003. The problem is the system won't boot or it freezes when it gets to the windows 2003 server loading screen. Or sometimes i get error Memory parity failure. I tried changing the RAM on the system but no progress. I also opened the casing and saw a red led CR59. Whenever this red led lits the system freezes whereever it is. I have tired searching for it on the internet and to no avail. Any help would be really appreciated. Thank you.
