Ok so I bought the right cable for my card and monitor.

But now when I boot my computer up this comes up.

The white thing in the top left corner blinks. It seems to be something where I have to type something.

Help?

It's not booting, you must of unplugged something most likely your hdd. Check your HDD it should have 2 cables to it one power and the other is sata which goes to mobo.

It appears tht these are the only cables I see plugged into my HDD

Good news!!

It is booting right now!

Hopefully will be able to join everyone in a moment.

Desktop is pretty dirty lol
