My computer will no longer recognize the memory


Try this >>>>

Remove the power cable and lay the computer on its side. Remove all the RAM from the unit ad make sure all the brass contacts are clean. After that take a look at the slots and make sure they are free of any dust.
Plug in the power cable and start putting the RAM back in one at a time turning the machine on with each module to try, that will determine which of the modules maybe faulty, it just maybe a case that you haven't put them in properly.

Good luck and regards.

Intel D946GZIS machine will not start after being reassembled. The green light on the Motherboard is on but after hitting the power button nothing happens

It is more than likely the power supply that is faulty. Newer PSU's have a 5volt supply missing, this means that some older boards will not run with the new PSU's. Try and find an exact match for your older supply but with a better power rating, if that is what is required.

My tower would not turn on when I came home from a vacation. Possible power outage/surge destroyed it. I replaced the power supply, and now I at least get the fan's running, but at various speeds. Still...

Easy Answer, YES MB could be shot.

Heavy dust/lint buildup can cause problems in this area. Unplug all cables from the box, remove the side panel. Remove all accessory cards from the motherboard. Optimally, use a compressed air blower to blow out all of the lint to pristine condition. Don't forget to blow out UNDER the MB too. There is about a 1/2 inch space between the bottom of MB and metal case and lint here can sometimes short between wiring and cause odd power behaviours. Make sure you blow out all of the edge connector slots that the accesory cards plug into. Blow out the power supply as best as you can.

Wiggle all the power supply connectors. Oxidation/microdust can make for intermittent circuits.

Before re-installing accessory cards use the eraser on the end of a pencil to rub the edge connectors until they are bright and shiny.

Re-assemble and give it a try.

If still no start, A bad drive can cause no start and poor power levels. Temporarily install another bootable drive or try booting from CD.

Last but not least. Corrupted firmware on the bios will cause your symptoms. A little known secret of bios systems is that there is ADDITIONAL firmware on most MBs that will boot from FLOPPY and auto install a new bios. You will first have to download the bios update from manufacturer for your MB, then put it in floppy, then unplug hard drives and CD drives then reboot. If the bios re-installs you are ok.

If none of the above works it is time to go to for a cheap MB combo.

Good Luck

Computer is not working, changed power supply and is sti dead

Try to unplug the power cable from the system for 2 minutes and then turn the PC on.

If that does not work, then look for the battery of the motherboard, it would be like a coin. Use clippers and remove it for 2 minutes and put it back in and power the system.

If that does not work then try and remove the one RAM at a time and restart your system.

If all the above steps does not work, then you would have to replace your MB.

CMOS Battery?

I am going to go out on a limb here and infer that when you try to power up the machine you get nothing - no lights, no display no beep. If this is the case then this would be symptomatic of a failed power supply, however the problem may not start or end there it is also sympomatic of a failed MB.

A good power supply will sacrafice itself to protect reliant components if there is a power spike, a "budget" one will pass the damage on.

In answere to your first question about the CMOS battery you are correct.

Basicaly buy a new power supply and don't buy budget but having done that don't be suprized if the MB has gone as well. Worse news is if you do have to change the MB depending on the age of your system you may have replace the CPU as well.

Sorry about the bad news, all I can offer on the positive side is that electrical equipment is usualy covered under a home and contents insurance package or a lease/rental agreement.

Hope this helps.

My Computer does not work at all.

more than sure if you have replaced the power supply already and the computer still not working,there must be a electrical damage to the board.
it is sure that.but you have to check some other components too seeing that they are stuck in the board,like the procesor and ramm dims or the video card..the electrical charge may have affect them too.
but 1st thing to do is to change the mainboard..
oh by the way...just to be sure..try to make a bios reset..maybe it will work and pull out the ramms from the computer..put them back after...ussualy this works...
good luck and let me know about

Try to use working processor from your friend, If the problem still the same possible your motherboard has been damage. Ask for a warranty for the supplier.

Power supply

Usually this will damage the power supply only. To make sure your that your motherboard is working, try to find a working power supply unit and connect it. If it does not work your motherboard may be get damaged. Also check for warranty. If your system contains a graphics card, check that too, it may also get damaged with voltage variations.
