I went inside my PC TOWER to find a cord unplugged, it's labeld "P4". I don't know where to plug it in for my PC and when I power my PC up, it shows no signal on my TV (I plugged the HDMI cord into it for a monitor) and there is no beeping sound when I turn it on. I have no clue and no expirence of this kind of stuff and I'm trying to get this problem through because it is annoying me.. PLEASE HELP!!!

Okay, the connector labeled P4 is a molex connector, it can be used to power various devices, if it wasn't plugged into anything before, then it's probably an extra.

In this case there doesn't seem to be anything wrong with your hardware, as your system is posting, your problem is likely that your Windows installation is screwed up, this might have happened if power was cut while it was updating or performing an upgrade or downgrade operation. The BIOS can't find an operating system to boot to, so it simply goes into a loop. You can try to access Safe Mode, by pressing the F8 key repeatedly while it boots and waiting for a menu to come up. It will give you a number of options including Safe Mode and Restarting from the Last Known Good...

Ima just wait until I get a laptop and if I need to I'll get a USB stick and install the stuff on there. Thanks for helping though, at least I know what to do if I do get a laptop.. That's for sure.
