Sounds like your mother board is fried, when you change out a battery sometimes static electricity builds up on your finger tips and zap and in most cases you wont notice it, it only takes a little bit to fry a mother board.

My dell optiplex gx260 has no memory chips and nothing show up on the monitor and it beeps 6 time can anyone help me


Make sure the keyboard is connected the proper port on the back of the computer. Turn off the computer and disconnect the keyboard and verify there are no bent burnt or broken pins on the keyboard connector or on the keyboard connector on the back of the computer Try a different keyboard on the computer. Unfortunately if all of the above recommendations do not resolve your issue, the motherboard may have a bad controller and will need to be replaced Hope this helps.

Turn tower on it beeps 5 -8 times then nothing the monitor is on and says in powersave mode and to move mouse or keyboard to enable but nothing happens no lights on keyboard or mouse


the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.
make sure that your RAM is securely seated
test or replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA 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 ?
hope this helps

No signal to monitor / Beeping


Listen to the pattern of beeps, or look at the back of the computer to see the pattern of the diagnostic lights ( 4 lights just under the keyboard/mouse connectors) and check out this site to see what they mean:

Nothing works on my dell optiplex gx 270


First, are you sure the power supply is coming on? Check by placing your hand at the back of the computer where the power cord plugs in, turn on the computer and see if you feel air blowing. It sounds like your power supply died.

If you're not using a quality surge protector, you may have fried the PS. Wal-Mart sells a cheapie one that goes bad quickly. If you spend less that $39.95 on a surge protector, you're basically wasting your money.

If the power supply doesn't come on, replace it, but you'll have to purchase it from Dell because they use proprietary PS - so generic won't work.

Mouse and Keyboard wont work after booting system?


First thing I would try is System Restore.

Start
Programs
Accessories
System Tools
System Restore

And go back to a date before this morning. This should take care of your problem most of the time.

Now when you say the monitor was black... do you mean because of the screen saver/power settings turned it black? Or did it go out on its own? If on its own, sounds like it might be overheating. See if it works once cold.
