Gigabyte GA-P35-DS3L No Signal To Monitor

[sswilson]

Can you get your hands on a S775 chip? That would probably be the easiest test.

I was under the impression that boards which would run the Q94XX retail version would have no problems running the Xeon chip. The Xeon chip I slapped into a Formula Maximus worked fine, and it wasn't listed in the CPU support either.

I am having a hard time trying to locate a 775 chip locally, everyone either has old pc's or amds... I guess I am going to have to call a local pc shop and see what they will charge me to flash the bios using one of there chips. either that or see if i can find an cheap used Celeron 400 Sequence 420 1.60GHz Conroe-L ..

I picked up an E1200 for flashing (awesome overclocker), and it worked for me, but I later found that it isn't natively recognized by all 775 boards (MSI 650i board ran it, but ran a bit funky WRT the FSB).

Just got my motherboard,ram and cpu back from an RMA with NCIX. They stated that they flashed the bios with one of the later versions and that everything works %100. Well I Am having the exact same problem, no video signal at all. I've tried two different video cards a 7900gt and a 8800gt, black screen is all i get.

I took my gigabyte board off the work station and setup my older amd 939 dfi street board using the exact same hardware except cpu.(520watt powerstream,one stick of ram, HD and dvd player) both video cards work fine on that setup but fail to work on the gigabyte board.

IF this board worked At ncix what could i be doing wrong? I've pluged in all the power to both the motherboard and video card, the monitor is plugged in...

Any help would be appreciated, it's been a month and I still haven't gotten to use my pc

The only thing I can think of from here would be the PSU. It wouldn't be the first time I saw a PSU which didn't for some reason play nice with a motherboard (DFI Ultra-D is a perfect example).

The Pc is powering up, all the fans are running and the HD spins up I am just not getting any video signal at all. If PSU was to weak or being flaky with this board would the pc still boot?

Yeah, it might have enough power to get the PC booted, but not enough to get the video running. Can you get your hands on a PCI (not PCIe) vid card?

Good Idea, thanks sswilson. Went digging through one of my hardware drawers and found an old Mach64 PCI video I'll give that a try in a few minutes.

I installed that pci video card last night and it didn't seem to help. I contacted ncix again and followed all of there instruction listed below and still nothing. If anyone has any other thoughts on what i could possibly do please say something.

This is a canned response I give out but generally one of these suggestions usually work for most issues......
I'd suggest the following to troubleshoot your system:
1) Plug the system directly into a different power outlet. We want to eliminate the power bar,if any, or the power outlet is bad.(done)
** Make sure to have a PC speaker plugged into the front panel header on the motherboard.(done)
2) Remove the RAM from the motherboard and see if the computer reports back with an error beep. If it does, try booting the system with only one stick of RAM at a time. One stick of the pair may be bad. (Removed and swapped both sticks of Ram and had no error beeps)
3) Completely remove and reseat the any video card from the PCI-E slot, making sure that the power connector is properley seated in the card.
4) Unplug the hard drive and optical drives and see if the system posts consistently. It may be a bad drive not allowing the system to post. If available, try another hard drive to test install an OS (I haven't seen anything on my screen, nothing but black or no signal message from various monitors)
5) Reseat all possible cables inside the computer again to make sure none may still be loose.
6) Clear the CMOS by the jumper on the motherboard. (took the battery out from (1-24hrs)
7) Try all the components outside the case to check to see if it may be shorting inside the case (working on cardboard atm)

Can you show us a picture of your setup?

Also, I had a customer complain that is new rig (that I built last week) didn't POST at all, while it worked the day before on my bench. The difference? A USB mouse. He removed is, and the rig could POST. I couldn't believe it.

Remove all USB components and try to power up. You just never know.
