Need some opinions here...I have a 4 year old HP. 400mz processor, 64mb sdram, and a 6 gig harddrive. I bought a digital camera and printer, installed the software, and she just crashed on me. I used the emergency start up disc, but now getting a bunch of errors, and freeze ups. Should I buy more memory for it and have it checked out professionally? Or just say it's old enough, not put any money into it, and buy a new one.
