so i just replaced my mobo and processor in my computer, new mobo is an ASUS M2N-SLI sockt AM2 and processor is an AMD 64 X2 5600+, and when powered up my computer the monitor doesn't display anything, almost as if the video card was not receiving power, or was fried or something. video card is an ASUS 7600 512MB and showed no signes of crapping out prior to the new mobo. as far as i can tell everything else is working fine, i can hear the hard drives humming and all lights are on etc. any thought? could it be just that i dont have the video card drivers loaded yet?
take out the video card and ram and see if the mobo beeps (u have to have a Piezo speaker when doing this) if it doesn't beep, ure mobo is dead.

Make sure the video card is properly seated. I just helped my daughter with her first PC build. We bench-tested the motherboard outside of the case using the CPU, keyboard, one stick of memory, and the graphics card. Lights lit, fans spun, but got nothing on the monitor. Turns out the card was in the PCI-e slot, but not quite seated snugly. Another possibility: does your graphics card have a supplemental power plug on it? My daughter's card took an extra 6-pin power plug from the PSU to get it up to speed on the Asus motherboard she's using.

Did you remember to plug in the 4 position power connection from the PS to the mboard?
What is the capacity of the PS you are using? - it should be at least 430 watts.
You must have a 24 position main connector from the PS connected to the mboard - a 20 position one won't work with this mboard, unless you use a 20 to 24 position wiring adapter.Make sure the monitor is on for at least a few seconds before you boot the computer.
Make sure you have the monitor connected to the primary video port - some cards won't display if you connect a single monitor to the secondary port.
"You don't need the video card drivers to get some kind of a display."
All video cards start up in a basic VGA mode that all mboards support, so you should have video before Windows loads no matter what, even with no hard drive installed, and Windows will load some kind of basic video drivers.
However, XP Windows often won't load if you are trying to boot a hard drive that has Windows already installed on it that was installed on another mboard if the mboard hardware is significantly different. Typically you see the first bit of Windows graphics then a black screen with a flashing cursor top left and nothing further happens. If you want to keep all the data already on the drive, you can run a Repair Setup procedure.Try removing the AC power to the PS and removing/re-seating the card.
This single card must be in the 16X PCI-E slot closer to the center of the mboard.
If you didn't remove the AC power to the PS while installing the card you may have damaged the card while installing it - ATX mboards are always powered in some places including some contacts in the video slots as long as live AC is being supplied to the PS. You must remove the AC power to the PS whenever you install or remove any mboard component or connection.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
http://www.computing.net/hardware/w...You can get no video if you are trying to use incompatible ram.
Did you make sure the ram you are using is compatible with the mboard?
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:

That's good, but you should tell us what you did to fix your problem so that others can benefit if they come across this thread

there were several problems that contributed to the whole situation i found out. 1) i had my old 420w power supply installed and apparently it was just under enough, cause i put in a 450w that i had lying around and it worked much better. 2) i need some updated ram. 3) i had, when my old mobo fried, used my friend's computer to run some diagnostics on mine to figure out that the problem was the mobo. i then reformatted my harddrive and reinstalled windows using his comp too, and it needed to be reset for my new mobo.
hope this helps any who need it.

Thanks for supplying details.
"1) i had my old 420w power supply installed and apparently it was just under enough, cause i put in a 450w that i had lying around and it worked much better. "
That may or may not have been the actual problem. If the 420 watt PS is an el-cheapo, it may not actually be capable of achieving it's max ratings (they lied in other words), or the PS may be defective, which is more common with el-cheapo PSs but can happen with any PS.
On the other hand I recently built a system for a friend with a very similar Asus model mboard - M2N-E SLI (I needed two IDE headers - yours, and all other Asus mboards with NVidia chipsets, has one) and used a good quality PS - Enermax - 430 watts - and the darn mboard freezes the system while booting sometimes (usually while the logo screen is on the display; the hdd led goes on and stays on forever). I didn't think the system needed more PS capacity because the ATI PCI-E video card I have on it does not need an extra power connection from the PS. It also reboots for no apparent reason when you try to do certain things, and sometimes when it does that it resets the boot order - the drive she boots from is IDE, the default is SATA - you have to reset the boot order to the IDE drive to get it to boot into Windows. I was assuming the mboard is defective up till now.
I have an Enermax 485 watt one I could try, but I don't think it will help.I discovered to my regret there is a known problem with using ATI chipset video cards in many recent mboards that have NVidia chipsets - something non-standard in the NVidia drivers clashes with the Catalyst drivers for the ATI chipset and they cannot load properly - ATI has known about the problem since about June but hasn't found a solution yet. I loaded Omega Radeon drivers instead, which come with a Control Panel rather than Catalyst that doesn't require a .Net Framework version be installed, but I had to NOT load the NVidia special IDE driver that is also reuiored for running SATA drives in SATA or SATA RAID modes, so her one SATA drive is in IDE compatible mode, 133mbps max burst speed, rather than 300mbps.
I ordered and received an EPOX AD580RX mboard that has an AMD chipset that should have no problem with the ATI AIW card's Catalyst drivers, and running her one SATA drive in SATA II mode. I will transfer her components to it soon."2) i need some updated ram. "
If the ram wasn't compatible, yes, that could certainly fix your problems if you then installed comptible ram.
If the ram you had in it was compatible with the mboard, that has absolutely nothing to do with your problems, but you may have a had a poor connection in your ram slots."3) i had, when my old mobo fried, used my friend's computer to run some diagnostics on mine to figure out that the problem was the mobo. i then reformatted my harddrive and reinstalled windows using his comp too, and it needed to be reset for my new mobo."
Re-loading Windows has nothing to do with curing getting no video display - you should get a display even if no hard drive is installed.
