Issue with New Build

[Royal Fleet]

Built a new PC and it has developed an issue.

When I start the box up, the fans turn, lights come on, and the machine sounds like it entering the boot sequence, (i.e. spins the optical drive), but then it just stops doing any more. The monitors never come on, and it doesn't do anything further, it just stays like that.

If I reset the machine after a while in this state it will then sometimes restart properly.

I have checked all the connections. I have tried booting from a boot cd rather than HD, but nothing.

My thoughts were it is a Graphics card fault. Any ideas?

(Spec is
Intel Core 2 Duo E4500 "LGA775 Allendale" 2.20GHz (800FSB)
Crucial Ballistix 2GB (2x1GB) DDR2 PC2-5300C3 667MHz Dual Channel Kit (BL2KIT12864AA663)
Asus P5K Intel P35 (Socket 775) PCI-Express DDR2 Motherboard
Gigabyte ATI Radeon HD 3850 Pro 256MB GDDR3

Have you checked you are running the right RAM voltages in the BIOS?

Also how long was it working before it developed this fault?

Not too long, the issues started on something like the second or third time the machine was booted (it is only turned off every other day or so).

If the voltages were wrong would it ever work?

Do you still get the beep at startup?
