Okay so i have been having problems with my pc lately. I had a preview of windows 10 installed on it. My pc froze and i couldn't click anything except i could use my keyboard. So I installed windows 7. Everything worked fine. I installed skype and stuff, until my keyboard spazzed out and so I restarted my pc. Once it restarts, it'll do a loop restarting. I had the option to boot into my hardrive or cd but it still resets after i chose either of them. So now I can't do anything, but i can go to my BIOS, so if there's anything i need to do, tell me. Oh and I installed windows 7 by mounting it in the virtual drives. I also have windows 7 burned on my usb drive, but it acts like a local disk.
