Back up any data that you want to keep, while the computer is still runnning well enough to allow you to do so. Then run chkdsk /f to try and repair the errors.

Are you running Windows 7?

If you can boot into the command prompt off your Win 7 DVD -

try running bootrec /fixmbr
and bootrec /fixboot

it looks like your disk has problems
before running chkdsk, best make a backup of your data
if that does not help, you either should replace the HDD, or try to repaor it with HDDRegenerator :  http://www.dposoft.net/hdd.html      
it repaired MANY drives for me
The event viewer error you posted shows a problem with the ISOdisk driver, which is classed as a boot-start or system-start driver by your system... except that maybe it shouldn't be.

At some time in the past, have you installed ISOdisk on your computer to mount and view ISO images as virtual disks?
If so, uninstall it and see if the error goes away. If you still have the problem, the registry may have to be searched and ISOdisk entries removed or disabled.
