restarted computer, now it doesn't work!

I realised something this morning- when the installer was doing its thing, I remember it installed K-Lite Codec Pack. I already have this codec pack, and if you don't know, having more than one is bad. Installing it was the only way to progress with the program installation, so I clicked yes without really thinking about it. I also thought the installer for it would recognise that I already have it installed, and then skip it. I was wrong though, and I think that might be the cause of all of this. It's the only logical thing I can think of.

I think this might be a two part problem.

1. my monitor driver is messed up, therefore I cannot see stuff. When I plugged it in with the laptop, I was only able to see the boot screen, but nothing past that (even after going in the BIOS and setting it to "Dual" mode with monitors. So I'm thinking I will just go exchange it and get a replacement?

2. The MBR or something along those lines is messed up too, hence what appears to be multiple loads (about 7) when I first power on. That would be a lot easier to fix once I can see :P .

So, as disappointing, worrying, and frustrating as this is, I'm feel that we are getting to the bottom of this, and the recovery can begin. Thanks so much for your help already

OK! PROGRESS! I am very pleased, in case you can't tell... :D

So anyways, I plugged the monitor into the agp slot on my mobo, and it worked. The problem is with the video card. With the card in the PCI-E slot, it makes the multiple boots, with it out, it loads normally. I've uninstalled the drivers, installed the latest, and still nothing. So, there is obviously some communication problem with the card to the rest of the computer. It's plugged in, etc, so this is a bit trickier. I went to the BIOS to make sure it's set to look for another thing other than the on board video and it is. I'm not sure what to do now. Is there something else in the BIOS I can alter to have it recognise the card?

do you hear any error code before BIOS starts?

its also a good idea to re-seat RAM and video card then check it again.

reminder: remove the power supply of your HDD while doing test to prevent form data corruption...
