Startup failure

Im having an odd issue with my xp home pc, worked fine yesterday and 10 minutes ago, but when it starts to load up the page where it says windows xp is loading, the screen is very faded as if not even completely loaded yet, and it remains there until i restart or shut the pc off, i cannot enter windows what so ever..

I have not installed anything new, all i did was uninstall battlefield 2, and this issue occured ever since.
ANy ideas?

I had a very similar experience a few days ago. It got to the loading screen like usual, and then the screen went dark, but instead of the monitor switching resolutions and then loading Windows, it just stayed dark. I hit the reset button and it booted up normally (with the little "Windows did not shut down correctly" boot-up menu). Then today I got a blue screen at almost the same spot in the boot-up routine, and the computer rebooted on it's own and loaded Windows correctly. My only recent change to the system was installing SP3, but that was 2 or 3 weeks ago and had no problems then.
