Windows Vista won't boot on my desktop

[Blumpkin]

My desktop computer just crashed. When I turn it on it just stays at the huge DELL boot screen. Windows won't start or anything. No key strokes do anything, not F2, F12, or anything else I've tried.

Windows Vista Home Basic
Dell manufactured (as mentioned)
1 GB RAM, CPU ?

I haven't tried any new websites or software in a long time, but my wife is always playing Flash media mini games (Yatzee, Diner Dash, Monopoly, etc from various sites) and don't know if it could be related. I run Norton scans regularly I have no idea what the problem could be. It was working fine, got shut down normally and won't restart.

Does it beep at all or give any sort of hexadecimal (A-F, 0-9) error/diagnostic code?

I just get one beep from it as normal when I turn the power on. The first screen that pops up is the big DELL image and nothing happens after that.

Is there any other information at all on the DELL boot screen? And the beep you get: is it a long beep or a short one?

I almost forgot. It did have a USB flash drive in it when I turned it off (just a 1GB with mp3's on it). After the first unsuccessful boot I removed it from the USB port but nothings changed).

That should not cause any issues...

Short beep as usual. The screen says F2=Setup and F12=Boot Menu like it normaly does. Everything looks fine, but it would only take a few seconds on this screen before. Now it's been stuck for at least 30 minutes with no changes or noises.
