Seems complicated, but I'll try my best to explain. I was having some overheating problems, so I opened up the PC, sucked out the dust and rearranged my SATA and Power cables. Then when I booted my PC up, my BIOS HD Detection gave me a message of "No hard drives", yet the Windows XP boot screen came up. Strange, anyway, I logged into XP and noticed a few of my programs were missing icons. Upon further inspection, my E: drive was missing. I reopened the PC and tried fooling around with settings, making it a master to the D: drive on my secondary EIDE channel, and I'm still doing this to no avail. Any suggestions?
