Good morning all! My HP Vectra will not power on. I was away when there was evidently a power failure (yes, the machine was left on and not connected to a surge protector). This has happened before and the machine has always powered right back on. Now however, it gives me the dreaded beeps.

There are 3 'sets' of beeps. Each set alternates a high, followed by a low tone. When the beeping begins, a tone is heard, immediately followed by the same tone, then it begins to alternate high and low for a total of 8 high/low tones (nine, if you include the first (repeated) tone). I don't know how to count this - is each set counted as 1 beep? If you look at the manual (link below), the codes this machine generates isn't there. The beep codes stop at 7.
If this IS counted as 3 beeps, according to the manual my memory is bad. I just installed another 512 plus a 133 SDRAM but the tones were still there, unchanged.
Is it talking about another kind of memory? I took the following information from the manual, which can be found here: HP Vectra VL420 MT (PGA) Socket 478b Pentium 4 Processor, Intel 845, ICH2 Chip Audio AD 1885, Super I/O, Flash BIOS (American Megatrends) 133 MHz SDRAM Nvidia GeForce2 MX Graphics Card.

You can do this by either uplugging the computer, removing the cmos battery located on the motherboard for about 30 minutes or using the cmos clear jumper (a little more info can be found on page 21 of your manual). According to your manual, it's a switch? So maybe all you have to do is switch it over for a few seconds, then back to its original state. Thank you again TheSmokingGun. I've attached the file.
The BIOS in this machine is AMI and I checked further on the HP website and there are other codes listed. I listened very carefully to the sets of beeps again and it seems that there are a total of 10 beeps in each of 3 sets. I hope you are able to hear the file I've attached. I then snooped a little further to see what HP said I should try before purchasing another MoBo. When attempting to turn on the machine, please note that nothing - absolutely nothing is spinning (disks, fans, etc) or giving any indication that it is starting to spin. In looking at the guts of the machine, there is one little green light above the last PCI slot on the MoBo, plus, the start button for the machine itself is also green.
I cleaned all dust from the machine. When I push the start button the only thing that happens is the code. As a result, here's what I've tried: 1.
Pulled the CMOS battery for 1/2 hour. Beep still occurs, unchanged. Switched the No. 5 switch to on, waited several minutes, then turned back off. Pulled the main disk (there are two HDDs in the machine).
Same result 4. Pulled the graphics card. Same result 5.
Pulled the USB hub from the PCI slot. Pulled the memory stick. Kept the old one out and put a new one in.

Took that one out and put another one in. Pulled the cables from the HDD and CD and reseated them. The beeps continue in every case with the missing component out of the machine. When I was looking around in there yesterday, I noticed that one of the pins for what I believe is the Northbridge i845 (?) is no longer attached to the Mobo.
If you look at this link: and scroll down to the schematic, right in the very center of the mobo you'll see a square, metal box with upright fins. It is connected to the mobo at each corner by a spring-like mechanism. Each spring hooks to the motherboard by a U-shaped piece of metal. I found that little metal connector and put it back on the mobo, reattached the spring - but it keeps popping off. Should I be scared? The beeps continue in every case with the missing component out of the machine.

That's the chipset's. It helps disperse heat from the chip.
Your processor has on, probably with a fan attached to it, but a fan isn't really needed for the chipset. This could be the cause of your problem. A few things could be happening or could have happened. Since that heat sink fell of somehow, you may have fried the chip. I don't think those chips have the same thermal shutdown protection as your cpu. Or, it's just overheating, and reattaching the heat sink could help it. You might need to get some thermal past and apply it between the 2 in order to help it.
You might also want to look into an aftermarket cooler, since you are having a problem keeping it on. However, I don't think at this point it will help. Seeing that it's only a heat sink, and not a fan, it wouldn't overheat in such a short amount of time to just see if the thing will boot. That heat sink could have been touching several parts of the motherboard and may have shorted something out in the process.
Look for burned up resistors and the like (you can google for pictures of that if you need to) As I said already it sounds as if the board is shot, regardless of how it happened. And I don't advise on looking for a new/used one, unless you really are not able to find something else. Most older hp models have proprietary boards, and you would probably need to look for an exact replacement, which could be hard to find, and maybe even too pricey to worry about.
