Hello, I run windows XP and I am getting a "delayed write failed" message popup after about 4 min of using computer. I've shut down/restarted but it keeps happening. Once it starts to popup my computer essentially freezes. As I understand it I may be having a caching problem (I did try to download a program yesterday which had a hitch) or my hard drive is failing. I was told if it is the latter then I must keep computer off to prevent total hard drive erasure/failure so I'm afraid to turn it back on to check my caching. What to do?? p.s. I am not very computer savvy but not totally clueless either.
