So today I brought my computer to my friend's house (the is a desktop, not a laptop) and when I had to go I brought it back to my house. When I hooked everything up at my house and turned the computer on, it started beeping. At first I assumed it had to do with the graphics card because my screen wasn't getting a signal so I removed my graphics card and restarted my computer and it was still there. Last time my computer was beeping like this it was the PSU. However I'm not sure what the problem is. Between the time I unhooked my computer at my friend's and hooked it up at my house, I don't alter anything in the computer. What is the problem?
