Try F8 & choose VGA mode.

If you have no video during the POST, chances are it's a hardware problem. Windows drivers aren't used during the POST. It could be mismatched memory, bad video card or chip, even corrupt BIOS.

That's if the monitor is good. Try a different monitor, just in case.

I'm assuming that
- if your NVIDIA 9600GT 1GB card has one or two power sockets on it that you have plugged (an) appropriate power connector(s) into that(those) socket(s) from the power supply), and that the card is all the way down in it's slot.
- you have plugged TWO connectors from the power supply into the mboard power sockets - the main 24 pin one, and another 4 or 8 pin one.

Asus M4A78LT-M LE

M4A78LT-M LE (home support page)

"Hybrid CrossfireX
Boosted Performance with onboard GPU and discrete graphics card
ATI Hybrid CrossFireX™ technology is a unique hybrid multi-GPU technology. It takes your gaming experience to the next level boosting PC performance by enabling the chipset’s integrated graphics processor and a discrete GPU to operate simultaneously with combined output for blisteringly-fast frame rates unleashing the graphics performance (For Windows Vista or later versions)."


"Chipset AMD® 760G/SB710
(AMD 780L/SB710) "

CrossfireX Compatibility chart
http://img.techpowerup.org/080719/C...

That shows the Hybrid CrossfireX video feature - both the onboard video and the video on a card in a PCI-E X16 slot working together - is ONLY supported by the 780G chipset if the card in the slot has a Radeon HD 2400 XT, HD 2400 Pro, HD 3450 or HD 3470 video chipset (the same applies to the 760G chipset) .

You have a
NVIDIA 9600GT 1GB

I know from experience that the Asus bioses are set by default to enable the Hybrid CrossfireX video feature.
By default, the onboard video is still enabled when a card is installed in the PCI-E X16 slot, and the if video chipset on a card is NOT one of the ones that is supported by the Hybrid CrossfireX video feature - in this case NOT a Radeon HD 2400 XT, HD 2400 Pro, HD 3450 or HD 3470 video chipset - you will get no video from the card in the slot.

What you need to do is connect your monitor to the onboard video port when the computer is not running, boot the computer - you WILL have video when the NVIDIA card is installed - and go into the bios Setup and find the setting that disables the onboard video (IGFX or similar) and set the Primary video or Initialize video first or similar setting to PCI-E X16 or similar., save bios settings.
You may see these terms.....
* GFX0: video controller in a PCI-E x16 slot
* GPP: video controller in a PCI-E x1 slot
* IGFX: onboard (built into the mboard) video controller
* PCI: video controller in a PCI slot

Then connect your monitor to the NVIDIA 9600GT when the computer is not running, boot the computer - you WILL have video from the card.

If you're getting no posting beep then it's not booting up. It may be your video card as already mentioned (suggest you temporarily swap in something less fancy to verify that) or something else. Check my # 2 here:

"am getting no beep when boot"

I missed that.

"I'm assuming that
- if your NVIDIA 9600GT 1GB card has one or two power sockets on it that you have plugged (an) appropriate power connector(s) into that(those) socket(s) from the power supply), and that the card is all the way down in it's slot.
- you have plugged TWO connectors from the power supply into the mboard power sockets - the main 24 pin one, and another 4 or 8 pin one. "

Have you ?
I should have said two or three connectors for the mboard power sockets.
The connectors from the power supply you use must fill the sockets they plug into. .
The one for the 24 pin socket is usually two pieces coming from the same wiring bundle - a 20 pin piece and a 4 pin piece - both must be connected - the 4 pin piece latches or slides onto the 20 pin piece on one end - they only go into their sockets in one possible place.
There is also a 4 or 8 pin power socket on the mboard that a connector (or two connectors from the same wiring bundle if it's 8 pin?) from the power supply must be pluggeed into to fill it.

Do you have a case speaker or some other sound device (e.g. a piezo device) hooked up to the pins for a speaker on the mboard ?
Modern mboards seldom if ever have a built in sound producing device for mboard beeps etc.

Also, in rare cases, there are no pins on the mboard that will produce sound - mboard beeps - from a sound device - you won't hear mboard beeps unless you have amplified speakers that are powered on and connected to the onboard sound (bright green colored port). (The mboard manual will not mention pins you hook a case speaker or other sound device to in that case.)

If you do have ram installed make sure it's all the way down in it's slots and installed in the right direction so that the bump in the bottom of the slot(s) lines up with the notch in the bottom of module(s contact edge.

Improperly seated ram can cause no error beep(s) and no video while booting.

Ram that is incompatible with using it in your mboard can cause the same things.

You will get no video in any case if there's no ram module(s) installed in the mboard. but you should get an error beep or an error beep pattern when no ram is installed.
A good test for incompatible ram or damaged ram or improperly seated ram is to remove all ram modules then try booting the computer - you will get no video but you should hear an error beep pattern if nothing else is wrong.


If any ram module was installed backwards in it's slot and you then attempted to boot the computer, both the backwards ram module and the circuis of the ram slot it was in are fried instantly. You may have noticed a foul burning plastic smell, perhaps you saw a small puff of smoke. There will be at least one damaged or missing (it was zapped - vaporieed - or it fell off when you removed the module) contact on the module, and damage evident in the ram slot when you use good lighting - black carbon deposits, plastic has been melted. You may or may not be vable to get the mboard to work, if you clean up the carbon deposits and any plastic that is bridging contacts in the damaged ram slot, and use undamaged ram in undamaged ram slots.
