I have an HP Media Center PC model a1357c. This computer has been with me for a while now, and the memory is failing slowly but surely, as if megabyte by megabyte. I've looked online and I've found a place where I can purchase an upgrade to 4GB RAM that would max out the memory (I currently have +/-950MB installed a.k.a 1 GB according to the RAM sticks). My question is, is this machine worth the 4GB upgrade? I use it for just about everything as it does pretty much everything I've ever needed. Also, should it be worth upgrading the memory; is there a processor upgrade or a general hardware addition/upgrade that someone would suggest?
