Question ID: 756929
I upgraded my computer with a new motherboard, CPU, RAM, graphics
card, and power supply.  Once everything was plugged in, I hit the
power button and not much happened.  All the fans are working, the
cd-rom revs up, and there's a green light next to the 24-pin.  But
the monitor stays black, and the on-button on the front of the chassis
doesn't light up.  I double-checked and made sure everything is firmly
plugged in, and even uninstalled and reinstalled the CPU and fan. 
Still, Frankenstein won't live.  I'm pretty sure everything's
compatible.  Why won't it boot up?

Motherboard:  Intel D975XBXLKR 1066FSB Socket 775 ATX
CPU:  Intel Core 2 Duo E6300 1.86GHz 1066FSB 2M L2 Cache
RAM:  512MB Dual Channel DDR2 PC4200 533MHz
Graphics Card:  XFX GeForce 7900GT 256MB DDR3 PCI-E
Power Source:  Thermaltake Purepower 2.0 500 Watts ATX12V 2.0

Hi grantmilo,

Check the power supply. Read the Output label and compare it to what
the motherboard needs to power up.

I hope that helps!

Have you made sure that the CPU power connector AND the motherboard
connector are connected, if they are not the machine wont boot. Also
as I found out a couple of weeks back, having a faulty CPU can prevent
some motherboards from showing any life at all.

Since you didn't mention anything about it, I'm wondering if you
may have skipped over the part where you painstakingly read through
all the instructions that come with the motherboard in order to set
the Front Side Bus jumpers to match the CPU, install the RAM in the
proper slots, and so on?

Here's Intel's support page for your motherboard:

From this subpage, it looks like you need to set the BIOS
jumpers to Configure (with power off and power cord removed),
and then boot up so the BIOS can check for compatibility and
make adjustments. Then set jumpers to Normal (as above) and
boot up normally:

You might also check the "board revision note" on this page
to make sure your CPU is compatible with the motherboard:

Here's the main support page for your board, from which the
links above derived. You may find other useful subpages.
Note the tabs for the different sections, as well as the
links on the page:

Let me know where this takes you...

There is no answer at this time.

1) It is very important that motherboard and cpu match.
2) check all jumpers
3) make sure jumpers for the voltage's are on correct ( not power
supply but cpu jumpers )
4) If all that is correct next disconnect all cards, cd drives etc.
5) leave only the video card keyboard & mouse and one mem card
6) you want to get it down bare bones so when you turn it on only the
bios will come up if it does then you know you motherboard works
7) Then put each piece back one at a time first mem cards etc.

Thanks for the comments... yep, everything's plugged in.  Power supply
should be fine.  RAM is in the right slot, but there aren't any FSB
jumpers other than the ones for sound, IEEE, USB, and BIOS.  The BIOS
jumper just has 3 settings: normal, setup, and recovery.  Amazon sent
me the motherboard without any documentation, which seems fishy.  I
also tried disconnecting all superfluous devices (sound card, hard
drive, cd-rom, etc.)  No change at all.
