Put in new power supply, computer will not boot up. Asks what type of power supply, when I answer generic the computer will not continue to boot up. When I go into bios it says power supply is disabled and will not allow me to enable it. Any ideas?

In Ubuntu 9.04 click on the main icon and select Restart.

- If Ubuntu is the only operating system on your computer you'll need to tap the ESC key as the system boots.

- If you have a dual boot or multiple-boot system the menu should appear on its own.

- At the root level you'll get a boot menu. Select the one that says "recovery mode" and press Enter.

- Ubuntu continues to load until you reach the Recovery Menu.

- Arrow down to "
netroot

" which states Drop to root shell prompt with networking and press Enter.

- Now, at the root type "
password username

" (where username is the account whose password you want to change) and press Enter.

- You'll be prompted to
enter a new password

.

- You will not see the password or any evidence that you are typing.

- Retype the password. If both passwords match you'll have successfully reset your password.

- Press Enter to continue booting into Ubuntu.

hope it helps

Ive been playing around with pcs for 20 years. Im not a professional in the field, BUT.. Just booting up, a 250 watt will do it. Now, if you are playing a power hungry game you would expect it to fail then. I think maybe the PSU you have has a problem. So, you should return it and probably upgrade while you are at it. So, same answer.. NEW PSU. And... You do not want to run a system underpowered for any extended time. You can stress any number of components.

Reformatting as per new system.

From what you say I presume you wish to put it back to when was supplied. If so, boot your computer and go into the Bios, select default settings.
Re boot your computer with your system disc in the DVD drive and when the menu asks whether you want to install a fresh system and format, select fresh system.
When your new system is installed, go to the manufacturers web site and down load the drivers for your computer then re-boot it.
Install Office and any other periferal software that was supplied with the computer and there you have a system installed bare PC.

Hope that helps.

I would suspect the power supply over the System Board.
You will need a large antistatic bag or antistatic mat plus a ground strap and a power supply checker.
Check the power supply using a power supply checker (about $10.00). Unplug the power connector on the mother board and plug the connector into the power supply tester. If you do not have a power supply tester let me know how many pins are on the connector and I will tell you how to test it with a volt meter. If any voltage is not present, replace the power supply. If you do not have -5 volts it was used for ISA slots and was completely removed from the ATX standard in 2004.
Do you have an onboard video card? If you do is that the video output you intend to use or a external video card? If you have onboard video connect the monitor to the onboard video output. Disconnect the AC power supply cord from the computer and attach a ground strap from your wrist to the bare metal of the power supply. The down side of static damage to components is you do not always see the damage immediately since static can weaken components causing future failure. Remove all cards from the slots except the video card if you do not have the onboard video. Be careful to touch only the edges of the boards not the connecters and place them on the antistatic mat or in the antistatic bag. Plug the power supply back in and see if the Power On Self Test (POST) displays the boot process on screen or beeps are audible. The error beep codes can change from the BIOS types but these are a few generic ones. It would be best to check your motherboard manual for a complete listing of error codes.
1 short beep – System is OK
No beeps – Bad power supply or system board
Continues beep – Memory error
1 long two short beeps - display adaptor

If no video is displayed and no beeps can be heard, turn the system off by holding down the power button for 5 seconds then unplug the unit. Verify the ground strap connection on your wrist and the bare metal of the power supply. Carefully remove the memory sticks handling only by the edges noting which slots they go in and which module was taken from which slot and place them on the antistatic mat or in the antistatic bag. Plug the power supply back in and see if a continues beep is audible. If yes, power off the unit and unplug the power cord. Put only one memory module in the first slot but do not put the same module in the same slot (swap them) if you have more than one module. Restore power to the system and see if the continues beep is no longer heard and you see video. If you see video and no continues beep than power the unit down and unplug the unit. Do the same for any other memory module which will help you determine if any modules are bad. This test is not a complete test but if any modules are dead you can identify them. If no video and no beeps the motherboard is the suspected problem.
If you have video and one short beep upon power on and all memory checks good. Power down the unit and unplug the power to the power supply inset one of the removed boards and try to boot the system to see if you still have video. If you do power the system down and repeat the same procedure for each card. If you do not have video suspect that card is bad.
Good luck and be careful to always touch the bare metal of the power supply with it unplugged before reaching inside the computer and touching any boards.

Here's what I would do first:
Boot from a Windows system CD (probably the one that came with your computer). At the first screen that asks if you want to repair or continue, choose R for repair.
When you get to the screen asking for the Windows installation,choose #1 (probably) and then hit enter when asked for the password.
at the C: prompt, enter chkdsk /p to scan the disk for errors in the file system. Then try to boot it.

I can only cover generic test procedures since I do not have the specifications of your motherboard.

Sounds like you need to change the CMOS battery, the time being wrong everytime you boot is a good sign but also it losing its settings in bios is also another sign

Apparently this model has a bad motherboard, which manifests as a power warning and eventually a refusal to boot up. You can replace the power supply (as far as I know, any generic one 250-watt or better will work) but it's unlikely to help. You can buy a new motherboard (and new power supply, if you want to) direct from eMachines, but it's also likely to fail pretty soon. Your best bet is to get a new computer (NOT an eMachines one) and put your hard drive in as a slave so you can get your data off.
