I have a Dell XPS 630. The mothermoard went bad and I changed it out with an identical motherboard.( TT-PWA TED- PP150, PWA: Druid/ Motherboard AOO, PCB: P/N 316769600067
TF-PCB-TED-PB150, PWA: Druid Motherboard AO1; T= 1.57mm 4 layer).
When starting up, the light on the motherboard is amber in color and the fans come on for about 1 second and then the power goes off. The monitor never comes on.
This is the first time I've tried repairing my computer. I am disabled and retired, so I have to fix this myself.
Please give me step by step instructions.
Should I install or leave the 4 memory sticks out for startup? Should I leave hard drive cable hooked up to motherboard on startup? What about the CD/ROM drives etc. The AMD Radeon 4850 Dual- P117a are installed on the motherboard. Any help will be appreciated.
I have the original Windows Vista Home Premium 64 bit SP1 install disk with product key.

Step 1) CLR_CMOS (if you need more details on this step just ask, i'll walk you through it); see if that works
Step 2) check all cables, make sure everything is plugged in.
Step 3) pull out all but 1 stick of ram. try it in each memory slot, one at a time. if that doesn't work try another stick of ram in each slot by itself. keep swapping slots and ram till youve tried every possible combo

Let us know where you are if this doesn't work.

Thanks. I need for you to walk me through the CLR_CMOS.
In the meantime I will only have one memory stick installed and have all the cables plugged in.
I found the section in my owners manual on clearing the CMOS.
It says to move the 3 pin CMOS jumper from pins 3 and 2 to pins 1and 2. Wait 5 seconds, then return CMOS jumper to pins
3 and 2. Should I go ahead and do this?

yep... that should work.

i like to be more thorough... so if that doesn't help, then unplug the computer, pull the battery out, do the jumper, reset the jumper after a minute or so, put the battery back in, plug in the system and see what happens.
