I have a HP Vectra VL420 P5761. My problem is described like this: When a i want to turn in the computer it's not start. i just hear a beep. I had changed the power supply, ram memory and the battery. Also I'd changed the coonfiguration on the dip switch to recover the BIOS, but again, this action failed. I don't know what can i do, please give me some ideas to recover my PC. Thanks
I know this is about a year later but I just had the same problem too last night.
When you turn on the PC it plays this crazy tone music right? If so, listen to it then at the end you will hear a couple of beeps. In my case my system beep twice at the end. 2 beeps for me indicated Power supply was in protected mode. Luckly I had a spare P4 PS laying around which solved the problem.
If you have different beep code google up "HP Vectra VL420 Beep Code". Standard beep code doesn't apply to this mobo since the BIOS is customized.
My power supply was a standard P4 ATX... no special design from HP you should be able to get one at any computer store. Beware just don't the cheapest one it cuz they aren't build to last and aren't reliable. Trust me I've seen too many people buying cheap power supplies and having them kill their mobo's.
If your PC beeps 3 times, It could be bad RAM or A Bad Video Card...
IF PC comes up and starts to do POST or trying to Boot-up, and then you hear hard drive clicks (like its parking the read head)and PC shuts down -- Check to make sure CPU is being cooled down sufficiently (always USE CPU thermal paste or Gel).
I have had 2 power supplies go out in my HP VL420 MT desktop, I finally installed a heftier Power Supply. I found a compatible power supply at Office Depot (I'm sure Staples,or Circuit City carry the same one).It's a
Antec® Basiq™ BP350 350-Watt ATX12V Power Supply
It had the correct dimensions and voltage outputs, But with more Wattage capability.
If it's just one short beep, then that is a memory check to say ok, but a second beep is normally heard which can indicate the graphics are ok, so check in the bios that your agp graphics card is set to primary graphics controller, if you have one fitted, or if onboard, check that on board is set at primary if not. If you know your graphics are correct, make sure that time and date is set correctly and there are no faulty drives that the bios is unable to identify. If it is a continuous beep then a motherboard or processor failure is indicated.

Hello sandrew's!
I'd reviewed you solution but i can't fix the problem. So I like to send you a sound file with the beeps that i described previously. In order to do that, i need your e-mail address, or tell if there are another way to give that sound file. Thanks
