My fiancee came home last night with some new toys for me... I have a new Sabertooth 990FX R2.0, FX-4100, Asus HD7850 and 8GB of RAM. Yes, I am a lucky guy and no... You can't have her. :p

Unfortunately, I appear to have connected something incorrectly (or something) as I am getting zero response from the monitor. I have the DVI connected properly (via VGA-DVI adapter) the power supply is correctly connected to the Motherboard and Graphics, RAM and CPU are both properly seated, as is the Graphics card.

I removed the graphics card and tried my old one (GeForce GT 520) but still no joy.

I haven't built a system in a very long time so I'm a bit behind in some of the tech (I was a bit freaked to see a motherboard without IDE support, for example) so I have no problem with the idea that I've connected a wire in the wrong place or whatever...

Before it's brought up... No monitor access, means no ability to see anything that's going on with the computer, which means no ability to install things like Windows or drivers... So, no... I haven't tried any of those kinds of things.

Thanks.

ok.

1) try a different monitor cord, insure your current cord and monitor works on a different system
2) try another psu that you know works
3) pull the ram out of the system and stick one stick of ram into the mb. make sure its seated properly, if it won't start, pull it out, and try it in a different slot, if that doesn't work try the other stick of ram in all the slots. if none of this works, plug ram back in and move onto the next solution...
4) pull the power plug, clr_cmos, pull the bios battery, wait a minute or two, put it together and try to start the system
5) pull the cpu out, visually inspect the pins, make sure none are bent, make sure the cpu is put into the socket propperly with the arrow matching up with the arrow on...

Try to reset the ROM from the BIOs, most of the times while changing the video card this seems to be an issue, and remember to always install drivers before doing a switch and cheking you'r BIOS settings for DVI,HDMI,VGA & Svideo priorities.
To reset the rom unplug your pc from power, open the case and remove the battery, some MoBo's have some pins like in a HDD.

5) pull the cpu out, visually inspect the pins, make sure none are bent, make sure the cpu is put into the socket propperly with the arrow matching up with the arrow on the socket, lower the bar to lock it in, reapply the thermal paste. If you do have a bent pin you'll have to try to straighten it manually, my preferred way is with a penknife and carefully straighten it using the rows and columns as guides. it doesn't have to be perfect just straight enough to fit in the hole.

lets know what happens after you've tried all of this.

Check The bios rev of the mb and look on the mb qal list for there CPUs.
Make sure the bios on the mb at a rev that will post. On new mb there is a four or eight pin power for the CPU. It near the CPU or on the edge of the mb. Make sure that power plug is plugged in. Make sure the io shield not shorting out the mb and you used the brass standoffs to keep the mb from shorting out.

the sabretooth will work on a 41xx out of the box. the bios is not his problem. the io shield is a great suggestion, however he said nothing about the cpu cooler so i assumed he was using the stock asus mounting bracket with the stock amd cooler. but if it's a third party unit... good thought.

Ingtar, you rock. I removed one stick of RAM and I have my monitor again... Not sure where to put the other stick just yet, but I'll have a quick look at the Sabertooth user guide and see what it says...

Thanks to all...

likely you have a bad stick of ram. You can check this by trying the stick in another slot. If the problem persists when it's in the other slot, it's bad ram, if the ram works in the other slot, it's a bad memory slot on your mb. Whichever the problem is, i'd return the faulty part and get another, the store should honor it.

After that worked, I checked out the book and found that they had a different recommendation for the RAM setup than both sticks side by side. I did as ASUS suggested, but got a memory issue warning when I rebooted (the post beeps, I mean) and went ahead and removed the battery for a few minutes. When I replaced it and put the RAM stick back where ASUS suggested (for 2 sticks) everything worked fine and the Bios is showing me 8GB of RAM :)

Thanks again for the help, everyone :)

awesome, i would run memtest86 on your ram, 1 stick at a time to make 100% certain they both work properly. You had enough issues with the 1 stick i would want to be 100% certain.
