System unit or power supply?

The computer power supply may have failed. Do you get the "post beep"?

If not- remove the BIOS battery, move the jumper to "Clear BIOS" . Insert BIOS battery, and try to boot. Put jumper back to normal position and try boot again. If you do not get the post beep, swap power supply for a known good one, and try boot again. If it still does not boot and give you a post beep, look to see if there is a removable BIOS chip- pop it out and put it back, this will clean the terminals. Go through and reset BIOS, as above, and try boot. If the system is functional, it should now boot up, but prompt for you to run the setup program.

If it does not boot, the problem is relating to motherboard/processor.

Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty because a computer has to have an end to the circuit any fulty leads will lead to no boot up
good luck

I have an old computer (not this one)which uses

How do you "warm" the computer, so that it will start properly?

Take a close look at the motherboard.
Look for those round "towers" with "silver" coloured caps.
They are capacitors.
If any caps are _not_ flat, i.e., they are bulging,
or if any caps show brown "rust" on top of the caps,
then those capacitors on the motherboard have gone bad.

Before your motherboard _completely_ dies, backup "everything" to an external disk-drive, verify that the backup has worked, and then either "trash" the motherboard, and replace it. You'll have to reinstall Windows onto the new motherboard -- find the CD/DVD set that you used to install XP.

Dell Inspiron flashing amber power light, not charging

I would think the batteries need replacing. That happened to my Dell Latitude CPI. The batteries won't charge past about 3%, so I got new ones and that did the trick. If this is under a year old I would contact Dell about it, if it is under a year old they should replace the batteries.

Hope this helps.

HP Pavilion 774y power supply replacement

I doubt you fried the motherboard
I would be taking my old power supply to the store where you purchased it to make sure they gave you the proper one.
Some power supplys do have that extra plug you may not need to plug it in at all
I can't see your motherboard to show you where to plug it in wish i could help more

Problem with power supply atx-300-12eb3

Faulty I should say, becaue you can repair it. Just replace the Buldgy capacitors. you'll need a soldering iron, soldering lead and a ****** to desolder the components terminals. Remember replace the caps with only the specific values indicated on them and also when replacing them see how you removed them is how you'll replace them and solder them back, if you not sure to do it yourself then provide the Capacitors and asked a friend who can do it for you. But if you think you can afford a new powersupply unit, thats fine.

Wet Dell XPS M1210

I would try cleaning the terminals on the battery and the computer with an old toothbrush and simple green or other multi-purpose cleaner, that doesn't leave residue.
