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!

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.

1-3-1 through 2-4-4
Memory not being properly identified or used
