Optiplex 755, 6 beeps, no display

So I was letting my friend try out my computer, and he raged and smashed the control tower. After I kick him out of my house, I turned on my pc to be sure its ok and now it won't turn on and does six beeps and no display at all. Here are the specs:

Optiplex 755
Windows 10 OS
Intel Chipset Q35 Family (Or something like that)
2 GB Ram

Please reply soon!

RE: Help, My Computer does Six Beeps When I Turn It on And it doesn't display anything on my monitor! What Do I Do?!

Video card is probably dislodged.  Open case and remove all cards then re seat ram.

Beep Codes

Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. For example, beep code 1-3-1 (one possible beep code) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.

Reseating the memory modules may correct the following beep code errors. If the problem persists, contact Dell for instructions on obtaining technical assistance.
