Windows 7: Beeping noise on desktop startup

So yea 3 year old Dell desktop that does this: Computer Probelm on Startup - YouTube every time I start up today (it goes through the exact some process as shown in vid, sorry for messy study). The only thing that can stop the beep is holding down the power button until it powers off.

That computer his a Core 2 Quad, 6gb ram 500 gb hardrive and .... well I can't really think of anything else that would relate to the issue (runs on 32 bit Vista). Any advice?



Thanks loads

Can you run memtest86?

Memtest86+ - Advanced Memory Diagnostic Tool

Also, try booting with your keyboard unplugged.
