Old hard drive crashed so am attemping to install a new hard drive with windows Xp OS. First try at booting up produces nothing but a green power button light and fans can be heard running.No picture-black screen.
Tried a trick shown on Toms Hardware.com web site regarding a possible solution which goes like this:
“Plug the computer into a power strip that has an on/off switch. Turn the power strip on. Press the computer power on button to start as normal, but after after one second turn off the power strip switch just long enough for the fans on the computer to slow down, but the amber computer led doesn't turn off and then turn the power strip switch back on. Computer should start and run fine. “
When powering up using this method a green power light shows, one beep is heard, then a message appears stating “Previous attempts at booting this system have failed at checkpoint pnp3. Contact Dell Support.....etc. Several attempts made with same results except checkpoint pnp3 changes to pnp 4,5,6,7 etc. Attempted some possible corrections by unplugging power supply,removing cmos battery, unplugging all ribbon motherboard connections and reinstalling. After removing and replacing battery I was able to get into setup once and reset date, time , etc. Then reboot went back to same no go error. Could this possibly be a bad power supply? Will appreciate any suggestions as to what to try next.
Many Thanks : Dick

Is this a laptop or desktop unit?
Hard to make sense of it until we know.

IS it a NEW hard drive?
What were the symptoms that made you replace it? At face value so far this sounds like a bad motherboard

This is a Dell Model GX-270 Desktop. Previous hard drive developed a clicking noise, then froze completely. New hard drive installed but now unable to get machine to boot.

that model actually had a choice of three cases - see http://support.dell.com/support/edocs/systems/opgx270/en/ug/index.htm

In my experience the small form factor version is especially prone to not starting after being worked on - simply due to damage when you take ti apart... Having said that, some Dell motherboards do seem to be incredibly sensitive about what hardware you attach to them

In a case like this, where a clicking drive is a pretty good indicator that the drive is at fault, what are the options?
!) the replacement drive is faulty
2) the replacement drive is incompatible - or is not jumpered correctly
3) something has not been reassembled correctly
4) something has been broken during the job

I'm afraid really this one is going to be trial and error.
Unhook the data and power leads to the drive. Does it boot then?
Remove and reseat the memory, all expansion cards, power connectors and ribbon cables. Check the connectors for bent or missing pins
Consider hat you may have a faulty memory chip. Try booting with just one chip at a time and see what happens
Will it boot with any expansion cards removed?
Check the BIOS settings - is the drive correctly identified? If a SATA drive is it set to ATA or AHCI or RAID?

You can then try a new PSU, but to be honest I have a feeling from your description that the problem is going to be the motherboard

Having tried all the suggested possible fixes [and then some] to no avail, it has been determined that most likely the motherboard is defective. Therefore I will close this request for any further comments but with many thanks to all who contributed! Thanks Again:
