I'm building a new system with parts from an older system.

Got a new Shuttle MOB, one 256 stick of 266 DDR, AMD atholon 1600+ & new case (all four items new). An older video card, segate drive & a cdrom (all 3 worked fine in scavenged system).

Problem #1: when I boot, MOB missreads type of ram and type of CPU. But when in the BIOS setup, selecting "choose optimum setting" , saving new bios setting - the system reboots with correct recognition of ram & cpu. The correct settings remain when soft-reboot, but if power down the system - settings are lost (have to go into bois and reset).

Does this sound like a dead battery ? next step is to replace it - yes ???

Problem #2: once I have reset bios and the system boots, the screen freezes (keyboard / mouse do not respond). I was previously running winme on the hard drive, but reformated w/ just Win98 boot only (I will load W2K), just wanted a clean formatted drive to boot into windows to regonize hard drive and CDROM so that I could load W2K.

At boot, the motherboard system check, passes the ram test & sees the harddrive & CDROM dirve - but freezes at the windows screen.

I tried connecting the drives in different config (master/slave- IDE0, Master-IDE0, Master-IDE1...) with no luck.

Took the drives out, just booted with Win98 boot floppy, same thing but screen freezes after ONE Second. EG - the initial menu that ask to boot with / without CDROM support comes up, (there is a time count in upper right corner), if I make a selection before the counter increase by a second, the system continues to boot and I can do "DIR" of the floppy - otherwise after one second everthing locks up. Of course, the system eventually freezes up no matter what I do.

QUESTION:

1. Does this sound like a bad motherboard ?

2. Could a dead MOB battery cause this ?

3. Could the powersupply be causing this ?
(the new case has a standard powersupply that comes with a budget case).

4. Could the memory stick cause this - it passes initial system boot test (I'm assuming that means its good) ?

5:. What is a good test sequence to perform (process of elimination) ?

Replace battery
replace powersupply (I have a new, much better PS sitting around - was saving if for my next system)
(I'm making the assumption that old parts are good since they worked before I scavenged them from previous system).
return MOB as defective & get a new one (luckly I bought the 1 year warrenty from newegg on this MOB :)

Thanks for any advice on best course of action

Since you already have the other power supply, try that and see if it makes a difference. Budget power supply, how "budget" are we talking? What brand/model/wattage?
