pc will not boot up

please help. last night i deleted a bunch of old programs that i had no use for anymore. i didnt turn off the computer and when i tried to use it today, it sounded like the harddrive was clicking. so i restarted the computer and it came back on and the clicking was still there. the "acer" screen appears and after bout a min the screen goes black with a white cursor in the upper-left corner. what can i do? please help

 

Your deleting old programs and your drive clicking seem totally unrelated. It was a coincidence that it happened when it did. With that said, about your only choice is to buy a new drive. Saving any data from the old drive is a crap-shoot at best. One thing I've had success with is to make sure the drive is cool, as in open the case and point a fan at it. This might give you enough time to save any data. Best to do this with the drive as a slave after you get a new one and get it back up and running, so you can drag and drop from Windows Explorer.
