corrupted rar file

i was extracting a rar file from dvd and suddenly everything stopped working, i took out the dvd and try to delete that file but not responding windows explorer appeared and desktop refreshes everytime

 

First, try a Power reset to clear things out:

(Step 1) Shut down and power off the computer.

(Step 2) Once the computer is powered off, unplug the power cord. If it is a laptop also remove the battery. It is important that any way for the system to keep getting power is unplugged or unhooked.

(Step 3) With the power cord unplugged and the battery removed (if you have one), hit the power button a few times as if you are trying to turn on the computer. When you do this and the computer tries to turn on, all the electricity is drained out of the system.

(Step 4) Plug the power cord back in and reinsert the battery (if you have one) and turn the computer on.

All done!

See if that does anything for it...
