Good Day
Good Day,
I understand.
1.Attempt to locate your Operating System Installation Compact Disk and Boot from it if possible, after you boot from it, press "R" to proceed to the Operating System Repair Option, then select "Fast Repair (all repairs), Then it will attempt to locate your Operating System, when it does, select it, and have it repair it.
NOTE: Your computer mouse will not be accessible as your drivers will not be loaded.
2.Please back up all of your data immediatley.
I believe that your Computer's Operating System may be corrupted/heading down that road, and will crash shortly.
