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.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

I recently purchased a Dynex 400 watt atx power supply for my Dell optiplex gx280 (slim form). The reason I did this is I have a new PNY geforce 8400 GPU and my old power supply is only 160 watts (1/2 the...

Sounds like the power supply is not compatible with the motherboard. If the motherboard can't support a 400 watt powers supply you will either get a blinking light or nothing at all. Those optiplex's use a proprietory power supply because of the pin connectors and how a power supply is supposed to fit in there. If you can't find a 400 watt power supply that fits then get a hold of Dell and see if they sell one for that computer.

My monitor turns itself on and off with no prompting

Go into the control panel and check the system settings. You might have it set to turn the monitor off after a low number of seconds of use. If you have it set for 30 seconds, if you don't use the keyboard or mouse for 30 seconds, the monitor will shut off. When you start to use it again, it will come back on.

System is not workin properly

You might try this. Shut down the computer, disconnect power cords, disconnect everything at the back of the computer, mouse, key board, etc. Open the case, ground yourself by touching an unpainted area of the case and remove the power connectors to ALL optic drives and floppy drive if you have one. (Of course do not disconnect the hdd.)
Reconnect mouse, keyboard, etc., and power cords to wall outlet.
See if it will post now. If it does I say you have a faulty power supply.
I was given a computer which was doa. It would not post, after I tried the above routine it posted then booted to windows.
I replaced the psu and now the computer works fine.
Hope this helps!

I only have the mini tower - need appropriate cabes, cords, etc.

First, I suggest finding a monitor first as some have an 'attached' monitor cable and some don't. (No use buing a $15.00 cord you don't need) As far as a mouse goes, believe it or not, I've found the best prices for a good mouse at Home Depot and Publix Supermarkets. E-bay and always have great prices on most any cord.
All PC power cords I've ever seen are the same (about $11.00 at any Staples, CompUSA, Best Buy, etc.), They are will only fit PC's and VGA (old-style) monitors.
Any monitor should work just fine. For used I'd suggest and for a new LCD you probably can't beat (new owner's of CompUSA).
Any mouse & keyboard will work also. Good Luck!

Dell Optiplex G110 power supply unit replacement

Yes you can replace the old defective power supply with the new atx but the problem is the size. It the size it fit to your computer nothing to worry because power supply now is almost the same output only the wattages changes.
