Compaq presario C700 continous beep when starting up

Potential Hard Drive failure, (Hard drive s.m.a.r.t. beep) or if MB beep it's chassis intrusion..

1. Remove battery + disconnect power
2. Hold down power button for 20 seconds
3. connect power only (no battery)
4. Turn computer on.

If the beeps stopped.. get a new battery, if the beeps continue..

Install sata disk

From what I was able to find it looks like the board is set for IDE Interface connections for the hard drives. But you can make it accept SATA Drives by adapters that plug into the Power Supply cables that go into the hard drive.

I'll show some links below that will show you the adapters you will need.

The link below shows the Cable that would plug into one of the power supply cables and go into the SATA Drive to give it SATA Interface.

The link below shows you the cable you need that will supply the Power to the Sata Drive. It too plugs into one of the cables that come out of the Power Supply and goes into the Sata Drive.

During the boot up process are there any beeps? If so how many short or long? 1 short beep is typical of a normal boot indicating no conflicts. What you can also do is unplug or remove any unnecessary peripherals (i.e. Hard drive, cd drive, any expansion cards) So that all you have is the the power supply, monitor cable, motherboard, cpu, and memory plugged in and attempt to boot. If this is successful add one peripheral at a time and boot again untill the boot fails again. This will usually indicate a problem with the power supply, either its faulty or not providing enough wattage to support all the peripherals, otherwise its a conflict with the specific peripheral that causes the failure. IF none of that works attempt to reseat all your connections, cpu socket, memory socket, power supply, and video cable. If all that still fails it is most likely a bad motherboard, its not unheard of to receive a DOA motherboard. As a last ditch attempt you can determine is a faulty video chip or the motherboard itself by installing a pci video card and seeing if its successfully boots.

I installed a new power supply on my pc cause it would not turn on at all, after installing the new power supply it turned on but then poered donw after a few seconds, what would cause this issue?

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

Dear, friend

When connecting IDE devices in your computer, there are a few rules you need to know about.
First, Master and Slave devices are different for the 80-wire cables and the 40-wire cables.
Inside your computer, you generally have two (2) IDE hard drive controller connections. They look this this 99% of the time:
[ The smaller one on the very top is a floppy drive controller connection )

Faulty Power Supply?

Take off the center heat sink and check the coprocessor. I bet you find it is black as it has overheated and fried the board. From what i have heard from my other techie friends they state that the power supply puts out to much power for the board to take and as you can tell... your problem and mine with the above stated board is that we need to replace it and throw away the old one.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
