Help booting computer.

I just got finished building my first computer, but I'm having problems booting it up. It turns on, but it doesn't seem to get past the POST. It detects my graphics card (XFX 8800gt), processor(Core 2 Duo e8500), keyboard, and then my RAM (2x2gb Kingston) After the RAM comes up, nothing happens. My motherboard is the MSI P7N SLI. Any idea on what to do?

install windows?

Install Opera

I run opera and a virus together in a sandbox just for fun.

Then I run the corrupted exe again just to see that hemorrhaging abortion of a browser writhe in pain. Just for the fuck of it.

That is not amusing, you most likey installed a corrupted version of Opera as it does not struggle with viruses as it is by far the superior browser due to its massive stability and low RAM usage
