Optiplex won't P.O.S.T.

Started a couple of weeks ago. MOBO battery going dead. Having to press F1 to continue startup. Yesterday my trusty old SX280 started spontaneously restarting every few minutes. I got a new battery and dropped it in, closed up the case and now. It wont even get to the first part step of posting. No video, no fans spinning up no hard drives spinning up. But the lights come on at least the orange light not the green light comes on. I have not found any info on resetting jumpers and what that might be. Also all components are standard unmodified from the factory one hard drive one video 1.5mg ram.

If it isn't POST'ing, you may have insufficient power (or a bad power supply) or a bad motherboard.  The same symptoms of spontaneous rebooting can occur for either situation.  Try swapping the power supply from another similar machine, and inspect the motherboard for bad capacitors: www.badcaps.net.  Also try the system with just one RAM module, the video card, the cpu and the motherboard.

Make sure your wiring is connected and that nothing is loose. While you're inside, make sure that you CMOS is in correctly. I've had systems that acted in the manner you've mentioned. Some of them (Old ASUS boards), I could get up and running again by reseating the motherboard Molex (power) connector. If nothing is loose and your components and wiring are seated normally you may have a failed power supply or board (as mentioned above).

Kinda what I thought. I just thought it ironic as soon I put a new batt on the MOBO. She goes down for the count. I was hoping that with a new batt I had to do some jumper this or that pin after a batt replacment.  Tomarrow I will let you know if I am able to recesitate with the above mentioned suggestions. Thanks
