My daughter has a dell gx260 computer which was given to her. It is a pentium 4 2.4 system. I upgraded the harddrive and got a message that the system can't find the harddrive. I needed to clear the bios in order for it to be recognized. All seemed well for about 5 days. Then just last night my daughter booted up and got the message that the system can't find the hard drive. Nothing inside the computer was touched. I can clear the bios again but just wanted to know if anyone else has ran into this with a Dell and if they found a permanent fix. Thanks.
