Hi ccain07 sorry to hear your having these issues,
Couple of suggestions;
1: Try resetting the MB BIOS using the jumpers (refer to user manual to do this)
2: On the new MB make sure the connections are in the right orientation (not back to front)**
3: If you need further assisstance post all the details you have about the system
you are working on not both, this will enable others to help you better & to deal with one
problem at a time.
Edit:** This includes the pwr on switch, power led, HDD activity led & reset button.

Here are the specs of my new PC (sorry, it's actually my husbands and I know nothing about computers...)
the CPU is an Socket AM2 3.0GHz AMD Athlon X2 6000 with 2MB toal L2 cache and my motherboard is an ASRock AM2NF3-VSTA. The GFX is 512mb nVidia GeForce 7600 GS.
He hasn't used his new motherboard yet so he hasn't done the MB BIOS but is going to try it as soon as possible. Thanks for your help, I'll keep you updated.
Update: He would like to know if he needs to turn on the PC after taking the battery out and flashing BIOS?

He just tried MS BIOS and the monitor still won't turn on and the power and reset buttons still don't work. Any ideas of what else we could try?

Monitors will display the no input signal until the computer powers up & sends a signal so I would,
Try testing the psu by bridging pins 13&14 or 14&15 of the 20 pin connector
that plugs into the motherboard, you can use a paperclip to do this & this
will establish if your psu is working at all, the link below shows 2 colour
diagrams yours is the type on the right; http://www.smpspower...rs-pinouts.html
Here is the link to your MB manual page 17 explains how you reset the BIOS (CMOS)

Hope this helps & let us know how it goes

Ok he tested the PSU, it works, and moved the jumpers. The PC still turns on but won't turn the monitor on.

Ok, are you still working on the older computer? if you are below
are possible causes/or things to check as part of the elimination
process; check the monitor lead & connections for any bent pins or
cable damage, remove the graphics card & memory sticks make sure
the slots are free of dust & replace the cards securely, swap the
CMOS battery on the motherboard, also I forgot to ask does your GFX
card have a seperate power supply to it & if so have you connected
it, see this link & you will see the power connector on the right
hand corner of the card; http://www.inno3d.co..._agp/7600gs.htm
