I would try 3 things -
1. Try a different graphics card as there may be a compatibility issue there, there are additional power connectors on the board for PCI -E power, 1 x SATA & 1 x Molex (use one or the other). Make sure power connected to graphics card itself, if required.
2. Try a different power supply if yours doesn't meet the ATX 2.2 standard.
3. Try different memory at default settings in BIOS (F9/F10)
Ok... I'll try that...
But here's another detail, I have this motherboard since a month ago. At the very beggining it give me a couple of troubles (restarting CMOS problems) sudently it started to work just fine... There was only one issue, when I install Windows XP when Windows ask for driver installations my mouse and keyboard didn't worked... I had to give it like 20 or 30 mins for one of them start working so I could use windows to recognize the other one.
But! 2 or 3 days ago I installed the Windows 7 RC and there was something wrong, something with my video it was like really really stuck (only playing video games)... so I desided to install XP back, I installed perfectly fine but the trouble with my mouse and keyboard came back... I leave it alone for 30mins and they keep not working...
And there is when my problem began...
Do any of this have to do with my problems now?
Ok, i'm done with that....
It's not working...
I'm thinking this is a motherboard problem... i mean, it could be broken or something like that cause i tryed to turn it on without memory... you know it should make a lot of noise, beeps and stuff like that... well... nothing like that happend... try turning on without video card but with RAM... no beeps, no nothing... and only with the processor and steel no beeps....
The motherboard is not giving me any sign of live...
we have a same problem
- Intel Extreme Series DP45SG
- Core 2 Quad Q8200
- Corsair TW3X4G1333C9DHX
- Video Card # 1
- nVidia PNY 9600GT 512MB DDR3 PCI-E 1.0
- Hard Drive # 1
- 500GB Western Digital
- Hard Drive # 2
- 500GB Western Digital
- Optical Drive # 1
- Samsung 22x DVD Burner
- Power Supply
- 500W Power Supply
- Sound Card
- On Board Sound
- Monitor topaz s 24'
- no beeps when I boot, no keyboard or mouse didn't working
- no operating system is new system and I don't have change to install that , because it's not booting at all, the power led is on , the fans start, but no monitor no bios screen.
- I thinks is the memory ??
In my case was the mobo, I maked some tests like turning it on without RAM or VIdeo Card... to hear some beeps, and that didn't work... the mobo was not responding
Try the most basic check - remove the battery from the motherboard and wait for at least 15 minutes to clear the CMOS.
Then with just CPU, FAN, PSU connected, power on the board and see if you get three beeps indicating a lack of memory.
This will at least indicate that the CPU has passed a basic check.
Then add 1 stick of memory and the graphics card and see if you get any video (get to BIOS)
I tried that and it didn't respond....
I already shipped the motherboard back for a refund... I can't tests any more...
I'm think I'm gonna get the Asus P5Q3... It is compatible with my Corsair RAM and with Intel 45nm processors (1333mhz FSB)
See this previous post where Lestat_L had problem with the board. And now it is fixed.
Hope it can help a bit.
Make sure to do the steps advised by Isit as well, he is right in telling you to do these basic steps. Isit thanks for helping out.
All the best,
I have the same problem here, but the problem is not the motherboard, but the Corsair memory. They are incompatible!

I put a Kingston KVR1333D3N9/2G and it's working fine. I'll buy the other module to run dual channel soon.
this board likes to PMS alot, i swear when i had it and was working great was an awsome board but when it started going down to sh*ts it was a hell of a board as it kept PMSing and not wanting to work right.
I know the watchdog feature is very problematic causing the moptherboard not to boot properly or just loop. I turned this feature off and all my booting problems were fixed, specially when i was overclocking. You're better off getting a different manufactures board, as this one is only guaranteed to become more problematic, and tech support from intel just sucks as they will keep refering you to the perfect set up which would be only tested and approved hardware for this board.
I went from one board that worked great and went to sh*t, rma and got 2 faulty boards back to back, learned my lesson from dealing with tech and customer support and got a new motherboard from evga, and havent had a problem since.
try resetting your cmos and boot to your bios by swapping the pin on the board, turn the watchdog feature off and then turn off your pc, switch back the pin to original place and start your pc like normal. like i said this fixed the booting problems for me when i had this boards but there was still issues with the board as sound, not reading usb keyboards at start up, and not working with 8gb of ram set at 1333.
this board is very picky on its settings
