Keeps happening , along with Error sign saying hard error! I've been told my hard drive is failing, or my operating system. Which one could it be? sometimes my pc tower starts clicking and when this happens my desktop icons sometimes disappear and then I have to reboot from the tower and then I'm good for a couple of days. I have repaired the operating system just a few days ago, thats when the NT stuff started. This happens every time I use the dell operating system cd. I checked for viruses and spy ware with what I have installed and also online with trend micro. Please help I need to be able to get my pictures out of my computer I only have a DVD drive. Ordered a combo but dell messed up and I didn't even realize it til just recently.
