Gabc, What do they have in their startup? Also, what processes are running?
Have you updated your Drivers?
Sounds like the mapping of the Drives is not working because of needing to updates.
Do the following and this should either repair or instruct you in what the problem is.
To start this process click your start button and then select run. In the box that appears type the letters cmd
Then select OK, once the dos prompt is up we are going to run a utility called checkdisk. To start this you need to type in this exact command belowchkdsk c: /f /r /x
Then select enter,
you will be asked if you want to run this process the next time you run your computer. Simply type Y for yes and then restart your computer.
This process will take you approximately 30 minutes to an hour depending on how large your hard drive is.
Post back and let us know what the results are and we will ssist rom there.
Thank you Jitaa
