primary disk not found

(a) If you computer was running normally and then suddenly started acting ignorant (any number of things) and the quit and now you cannot log on at all, your hard drive may have died. Were there any unusual (cla-clink, cla-clink, cla-clink) noises before it stopped working?

Did you recently move your tower or did it get bumped really hard? If you know what to do as in using a grounding strap or grounding yourself before starting to work and after shutting down the system and unplugging it from the wall, you can look for these possibilities: [1] Make sure your IDE or SATA cables are still securely connected to the disk and the mother board. [2] Make sure the power supply cables are still connected to the hard drive and [3] make sure the jumpers are still securely attached to the correct position on the back of the hard drive.

If the problem persists, you may need to replace the IDE ribbon and/or the jumpers. You may also want to try a different connection port on the mother board. If you have the hard drive as primary and the cd rom as secondary masters, try changing the cd rom to slave and connect both on the same cable (hard drive as master and cd as slave)

If non of these work then you may need a new hard drive. Thats my best guess but good luck.
