Just installed a new motherboard ASRock 775i65G with an intel Pentium D 3.4GHz, 800MHz FSB, 2x2 MB L2 Cache.
Disconected everything except
RAM, 2 x 1GB pc3200 DDR C8C3
Floppy drive
Hard drives internal 40GB and 60GB one with windows XP installed
Conected a USB keyboard and monitor to the motherboards built in VGA plug, but when i turn it on everything fires up and the power light comes on, the CPU and case fans are both running but the screen stays blank. The harddrive light comes on for about 30 seconds then goes out.
Only thing i'm not 100% sure of is the RAM but i've been told by several people that it's all compatible including the board manufacturer.
Can't hear any POST beeping as i've not got and internal speaker connected, all my previous pc's had them built into the motherboard.
Do i need to connect a CD drive and put in the windows CD or the disc that came with the motherboard.
can't think what else to do???
Any ideas or suggestions welcomed.

First of all, is it the right power supply for the motherboard. Use to be ATX but now they tend to have an extra 4 pin plug that goes beside the ATX socket and another 4 pin power for the chip.
Second thing, reset the BIOS. Means unplugging the power supply to the motherboard, removing a little back-up battery and moving a jumper for a few seconds. Check your handbook out.
Third, try new RAM from a shop.
Lastly, when switched on press the CAPS LOCK key and if the little light on the keyboard doesn't come on it would indicate a faulty motherboard to me. It should emit a fault beep so I suspect your motherboard may come under my "lastly" section.
Hop that helps.

First, take the motherboard out of the case and test it again on a piece of cardboard or something non-conductive and non-static.
Often times there will be a motherboard riser that is contacting the back of the motherboard where it is not supposed to. This will cause a short and make the board not post.
If it works fine out of the case, then try to find the part that is shorting it out.
If it still doesn't work, then I would try it with just one stick of ram, then switch to the other and see if that helps.
Also, just start it up with the processor, board, memory and video, sometimes a reversed floppy cable can cause that type of issue as well.

You'll probably go around in circles until you get a speaker installed. Most motherboards use the sound for diagnostics.
Try starting the computer with no RAM in it. some motherboards will still send a video signal.
You might want to try attaching a card-based video card.

Install only one RAM module in DIMM 1 (or DIMM 0, I'm not sure of the board's labelling). If it POSTs after this, switch RAM modules and try again. If it POSTs again, turn off and triple check your DDR configuration. Once you get a good POST with a single module, you should be able to reinstall the second one and start installing software.

Sometimes when you put old monitors on new CPUs the compatibility rate of the monitor needs to be changed. The only way I knew of doing this was to hook up a new monitor so that the CPU recognizes the settings and then set it back to the old settings. It has something to do with the amount of colors that are seen on the screen I believe. Good luck!

could well be an issue with the ram,try it with just one ram chip and then the other,does the board support 2 gb of ram ? perhaps it doesnt.if this doesnt make any diffeence then try a plug in graphics card even if its an old pci low spec card to see if it shows anything on the screen.

Whenever I've had this, the RAM has usually turned out to be incompatible. The one time it wasn't, the board was faulty.
It is also possible that the board is picky about which slots you put the RAM in.
Finally, check that your power supply is beefy enough.

Try this site to see if your RAM is compatible with your motherboard,

I trust you used a electrostatic band, when handling hardware,and installed your motherboards software
Hope this helps you
All the best

Double check the monitor connector for bent or broken pins. You should see a screen with just the monitor and the power supply connected.

1.Check to see if your power supply is up to the task.
2.since everything fires up OK, I would check the monitor itself next, try a different monitor.
3.if your Power supply and your monitor are OK, then it is probably a defective motherboard.
Hope I helped.
