After powering on the unit the compaq screen comes on and then is replaced with the message " a disk read error occured, press ctrl+alt+del" I was thinking c-mos battery but even after going into setup and accepting those parameters it never gets past this message in the boot up cycle.

The computer cannot find the operating system, the disk error message means it cannot find the hard disk, you most likely have a faulty hard disk or less likely a faulty disk controller.
You can test the hard disk by removing it and connecting it to a USB hard drive adapter and plug it into a working computer's USB port. If this computer cannot detect this drive as an external drive then you will know your hard drive is faulty ad you need to buy a new one and install Windows and programs etc..
when upower up thecomputer enter in bios setup press del or F2 or F1 to neter in bios setup when u power up.
thenr eset bios defaults settings.
then check your hardiskk is deteted or not.
if sata is enabled then disable then press F10 to save settings.
Since the bios hard drive test passed , ujr hard drive is ok and mostly all ur data is ok . Only windows went corrupt (normally it doest when u turn off that way ) reinstall it dont use the recovery disks , but use a windows installation cd to re-install windows , but take care that when u install ,install on a different partition and remember to take the option leave the current partition intact without changes , so that none of ur data is disturbed.
