Did you look for bad capacitors inside the power supply? I'd bet the 12V supply (for the video driver chip) is down. The first thing to do is measure the supply voltages to make sure they are within 5% of spec. Many chips will run OK at low voltage as long as they are cool, but once they heat up, they'll quit working. A bad cap on a DC power filter input will cause a low voltage on the filter output if the output cap is still good.

If you have the original Insignia Restore DVD, then all drivers should be available automaticly, but if you are installing from a Microsoft disk, then you'll need a Realtek AC97 audio driver and an Intel 82845G video driver for the onboard chipsets.( Sorry, you'll have to google for the driver links, Fixya's capcha, required to post links, doesn't seem to work anymore. )All other hardware varies too much, even from the factory when these computers were new, so you'd have to either track down drivers for those, or hope that Windows can find it while checking for hardware changes and updates.

The original power supply from the factory is very weak and under-powered. It will likely burn out if you add a graphics card or a second hard drive. I've upgraded and replaced the power supply on all of my Insignia computers so long ago that I cannot remember what the originals were, but any standard ATX power supply should fit the case and motherboard. I recomend at least a 400 watt to cover just about any PCI card upgrades, added hard drives or extra cooling fans, since that wattage can be found reasonably priced now.

Factory restore requires the OEM restore DVD disk. First boot the PC and press F2 during boot to enter BIOS. Change BIOS settings to factory default, to make sure the boot device sequence and all other settings are as they should be.Then insert the Restore DVD into the DVD-rom drive and save & exit BIOS settings. It should then reboot and load from the restore disk.

There should only be one screw called a "thumb screw" which can be gripped and turned by hand, then a slide latch that looks like a black rectangle of plastic (unless the plastic has fallen off or been removed, then it would be a metal tab) that you slide upward. While holding the latch up, apply pressure and slide the left side of the case back and it will come off.

To use Wifi on a D400 series PC, you would need to purchase a wifi PCI card (Do not get any PCIe or PCI2 or newer card specs) or wifi USB adapter. Since standard PCI is consider mostly obsolete, they can be found fairly cheak, usually under $10 usd on places like Amazon.

It should be able to boot from the DVD or CD rom drives before checking the hard drive by default, but somebody could have changed bios settings which could cause it to not work. The factory (OEM) restore disk is DVD media, so you would need to use the DVD drive.F2 during bootup to enter BIOS and check your boot sequence to make sure that the DVD drive comes before the hard drive. Also, the card reader on D400's tend to fail and no longer work, so it may be a good idea to dissable that from the boot sequence. The card reader can usually be found as a USB device in the boot sequence menu.

The D400-A PCs's were unfortunately made before the PCIe specs became standard. Almost none of the newer video cards will work, but I was lucky enough to find an nVidia GeForce 9400GT 1GB card that fits standard PCI. Be careful shopping for one online, make sure the product details state that it is the PCI version of the card, not the PCIe version.

It it would seem to be overheating, so it could be the CPU fan that is faulty, or the CPU Thermostat. In either case it would need a visual inspection to be 100% certain.

This could be any number of things. First thing is to determine what the problem is is to remove everything from the motherboard but the cpu, fan, and monitor. Turn on the computer. Does it beep? If so, then put the memory back in and try it again. If not, then the motherboard is likely the culprit.

The motherboard can only take 2 GB of memory. If you tried a larger memory stick in any slot, the motherboard will fail to recognize it. A larger hard drive or an external drive will only increase storage and page file capacity. This will not improve the performance of the computer. Memory caching to the hard drive is limited to the bus speed of the hard drive interface (much slower than the RAM). The better option if you can offered it is a new computer, if you do any gaming. You are dealing with a 2.8 GHz CPU with a 400 MHz bus. The computer is probably fine for e-mail but video and gaming response will not improve. I wish that I had better news for you. Cindy Wells (who replaced her Pentium 4 system that took 4 GB of DDR memory a few months ago. Too many other parts were failing.)

Unplug all electronic cords connected to the computer.

At no time during the installation should any cords be connected to the computer.

Remove the screws holding the computer cover case, and remove the cover case.

Locate the computer power supply box, which looks like a large box out of which a bundle of wires run and connects to the power cord jack on the outside of the computer case.

Unplug the power cables from the internal devices connected to it.

Be careful not to damage any of the sensitive control boards or devices inside the computer, and be certain to remember write it down if you need to what devices will need reconnecting to the new power supply when you finish the installation.

Unscrew the power supply from the inside of the computer case and remove it.

Check the original power supply's red voltage switch for the correct setting.

It should read 120 or 240 if you live within the United States.

Confirm this setting as the correct voltage setting for your power outlets.

Make sure your new power supply gets set to the correct voltage setting before you install it.

If it cannot be set to the correct voltage, do not proceed with the installation or you may damage your computer.

Return the new power supply and buy one that is compatible with the voltage requirements.

Install the new power supply, reattach the screws that will hold it in the proper place inside the computer.

Reattach the power cables that come from the new power supply to the devices that were connected to the old power supply.

Make sure all of these connections are firmly in place before you turn the computer back on.

Reattach the computer power cables and all the cords connected to the computer during normal operation, but do not close the computer case yet.

Keep your hands clear of the inside of the computer case as you attach power cords and peripheral devices.

Turn the computer on and observe the performance of the computer without touching anything inside.

Do all the computer fans function normally?

Does the computer operate as well as or better than before?

If you feel that the computer behaves normally and you do not encounter any problems, turn the computer off, remove all the power cords and peripheral cables once more, and close the computer case.

Then reattach the power cords and peripheral cables and begin using the computer.

Check for errors if you encountered any problems starting the computer or if it would not start at all, unplug all the power cords and computer cables connected to the computer and look inside.

Make sure that you connected all the correct power cables inside the computer securely and did not miss any.

If you have confirmed this and the computer still doesn't start or operate normally, call your computer manufacturer or a professional computer repair shop for assistance completing the installation. Most power supply units will fit Like everything else in our high-tech world, power supplies come in myriad sizes and shapes you should check all the electrical connections before you make a decision and make sure they are the same as the ones that you will need to run your computer also Check the measurements inside the frame to make absolutely sure it will fit,
