I made sure to install everything correctly, but the first time i turned on the computer with the new PSU, it started, lit up for about a second, and then shut off. After I unhooked it i heard a strange whirr or woosh noise come from the PSU. Is it a faulty unit?

Re: Newly installed, first boot up PSU problem
If it's a new PSU, then return it for a replacement...Even online distributors will replace faulty units.
And since your old PSU works on it, I'd have to say it's the new PSU that's faulty.
Did you make sure that it's the right PSU for the CPU that you have? (As there are PSU units for AMD and seperate ones for Intel...Intel just has a additional power cord to connect to the motherboard)

Don't panic. take a good light above your computer and start checking if every card and every connector is still correct inserted. Feel if nothing is lose. Even cards you did fasten with a screw, remove the screw and look and feel if the card was inserted correct. Everything you inserted in the motherboard should be checked. It could be a card you did not put in correct at the first time, but still made contact and only got lose because of some tension to shock.
hi, i had a similar issue some time ago, dependng on your hardware i would suggest you look into a psu tester, or swap it out for a friend's psu, i assume you've ripped everything apart and put it back together to see if some dust was shorting somewhere, is it related to heat maybe, expansion of cracking can sometimes occur in computers that have gotten hot in the past, especially in the circuitry behind the cpu.
Test your PSU or replace it if your power supply units fan
is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including
the leads from your"((MOTHERBOARD TO THE HARD DRIVE))"make sure they have a secure connection and
are not faulty or just replace them they could be faulty make sure all leads that
are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections
and are not faulty even the electrical extensions or just replace them they could
be faulty a computer
needs its connections to continue its cycle and have an end so any faulty leads
will end up with a computer errorhope this helps
Hello there: It looks like to me that your bios is not recognizing the harddrive or is not set up properly like user settings or default settings I would first go into bios and make sure that the bios is set to the harddrive that is installed. And also in the boot sequense look on this and see if the harddrive is listed there if it is make sure that it is the top one and not the bottom one than save and reboot the computer when it boots back up it should tell show your harddrive and cd rom if connected properly than if all is good now just continue with your xp[ installation or what ever you were doing ok I hope that this is very helpful for you best regards righard
Hi, This could be a hard drive problem. The hard drive is looking for the boot sector on it, but the boot sector is broken. Computer shuts down and tries again but your hard drive can't find the boot sector so it shuts down tries again etc.
Let give it a try.
Turn off your computer and unplug it from main supply. Remove the battery for cmos bios. wait half an hour. insert battery again and reset the cmos through jumpers. Plug the main supply and start your computer.
May be it can help you.
Have you installed RAM? If not the machine will not boot.
You may also need to enter the BIOS setup to set the CPU and DRAM voltages and multiplyers etc. Follow the instructions in the manual for setting up the CPU info in the BIOS.
Are you sure your PSU has enough guts to run the setup? Many times have i seen setups fail because a cheap power supply has been overstretched.
