Unable to boot after flashing to new bios, tried various suggestions t

Recommended Posts

just a quick question, but does the tx750 have a connector that can plug into the 4pin connector (the one next to the 24pin atx)? i noticed that i dont have a 4pin plug from the psu.

alright so splitting the 8pin connector and plugging only 1 of its 4 pin set connectors into it powered it on and posted. finally! but the issue now is that it hangs when i try to run the setup for vista. it just shows a colorful screen in the background and thats it. it doesnt even get into setup. so i tried installing xp instead, but it always seems to hang when i try to format it. when i set the partition for installation to 130gigs, it hangs after it reaches 2%. when i changed the partition to 50 gigs, it stops at 6%. something to do with the hard drive?

 

let me know what you guys think. thanks!

Specialistx,

 

After installing the new BIOS chip, did you reboot, enter BIOS and load optimized defaults, save and exit?

 

If not that is the first step.

 

After you've done that, then you need to run Memtest from your BIOS before even attempting an OS installation. Run tests #5 and #8 twenty loops a piece. If those pass, run the entire series of Memtest tests for 3-5 loops and see if that passes also.

 

If all Memtest testing comes back clear, it's ok to proceed with your Windows installation at that point.

 

And by the way guys, I'm still befuddled as to the rush by everyone to flash to that 0406 BIOS revision lately. IMHO the 623-1 and 0704-2bta are still the best two BIOS revisions ever released for the Ultra-D and SLi, SLi-D and SLi-Dr (non venus) versions of that board.

 

And I'll second what Rado said about flashing methods;

 

Winflash is an absolute no-no, no matter what DFI or anyone else says. If you have a DFI board then the three best flashing methods are;

 

TMOD/Loggan BIOS Flash Utility CD

Floppy

USB Stick

 

In no particular order - although the CD is awesome and I've never had a flash failure using it.

yes ive done the load optimized defaults. i usually do that as standard procedure whenever reflashing the bios in the past.

 

are you sure i still have to run memtest? prior to the reflashing bios garbage i went through, ive had no problems running my setup. never had any issues with my ram, and i do believe ive run the memtest before many times prior during those days.

Do as you like. I'm only here to make recommendations.

 

Do I run Memtest before ever proceeding with a fresh installation of Windows on new or re-configured hardware? Yes I do.

 

Do I run Memtest every now and then even on rigs that have apparently been stable for months? Yes I do.

 

Do I re-run Memtest when I'm trying to complete an OS installation that hangs repeatedly at any stage of the OS installation? Yes I do.

Apparently I just did what the OP did to myself. I have a new monitor on the way and for no good reason figured I should update to the most current BIOS from 623-3. Now I have no post/boot and fans running. About to try the extended CMOS clear I guess.

 

Thanks DFI, thanks a lot. This system had been running for 2 years flawlessly. I go to the DFI web site, make sure to pick the right product and follow their steps to update it with Winflash - and kill my system. :(

 

EDIT:

LOL ok well...that was fast. Before doing the whole tear down thing I read through the steps, plugged in a PS2 keyboard and booted with the new BIOS while holding down the insert key and it worked. Now typing this on the system itself. I guess I will just go back to 623-3 since that had been working, like forever, for me.

Lance,

 

That's good news.

 

SpecialistX,

 

Did you follow ExRoadie's CMOS clear procedure to the letter - exactly as Lance has done?

thanks for your help everyone.

 

the solution was:

 

1) new bios sent from dfi to me

2) plug in the what looks like 8pin connector by splitting it into 2x4 pin connectors.

 

im happy and running! thanks again!
