I can only boot when I clear the CMOS. If I get into Windows and restart the computer..It wont boot again..It wont even reach the bios. I have to manually clear the CMOS..
Please post full specs of your machine, brands and type of memory, psu, and vid card. The DFI boards are known for having numerous problems with cold boot and/or warm boot and some of your components can affect bootup.
ahhhh.....the dreaded cold boot issue. google "cold boot and dfi" and you will see you are not alone. strange thing is that something that fixes one persons board doesn't always work with someone elses.
for me and my dfi nf3-ultra, i had cold boot problems on the original 6-02 BIOS, but once i flashed to the 7-11 BIOS the problem dissappeared. Note that i didn't flash to the newest 8-24 BIOS because it is plagued by problems.
head on over to dfi-street.com forums and search around for cold boot fixes and the best BIOS for your nf4-ultrad-d. usually a BIOS flash will fix the cold boot issue, but there are numerous other tricks that might work also . good luck.
I was also reading some threads on this issue at the overclockers.com forums and a lot of folks are also placing the blame on DFI using crappy FETS on the boards too.

DFI claims its my memory. I have now tried three differant brands with the same results.
Tried slowing it way down manually also. Flash back to the original bios and it runs again.
