Gigabyte GA-P35-DS3L No Signal To Monitor

[Mulder]

Please excuse the quality of these pictures they were taken at my inlaws house with zero lighting and a poor quality phone camera and unfortunately I was at the will of the photographer so there not exactly what i was looking for. in all of these pictures all I have connected is power,cpu,cpu fan,ram and a video card nothing else no drives or fans or anything else. The first three pictures are off my old 7900gt and the last seven are of the 8800gt. I alternated from my gigabyte board to my old DFI board with the video cards so people could see that the cards work. I've tired many different sets of ram in my gigabyte board as well as four different cpus and nothing I do seems to get it to post.

Thanks for the pics - nothing out of the ordinary. But I've read your thread over again and saw something: are those sticks on the DFI board some GSkills? I'm asking since the DS3L defaults at a low 1.8V Vram. And those Mushkin Redlines need 2.0V. Try to find a stick of ram that needs 1.8V to run - that just may be it. If so, raise the Vram to 2.0V and reboot using the Redlines.

Yes for the pictures I ran Gskill Ram on the DFI board, I've run a few different cpu configurations and was forced to purchase a celeron cpu as apparently this motherboard wouldn't post without it. I've tried ever hardware variation I can imagine and haven't had the pc post.

... but have you tried some low voltage ram on the DS3L? Depending on the ram sticks, they still could be asking too many volts.

I still can't understand how NCIX managed to POST. With so many different hardware combinations, your board should have posted at least once! Only aspect left is the PSU.

You've pretty well tried everything but a newer PSU. Wish I was local to you and I'd offer to swap something in to see if it does the trick. Kinda sucks to have to purchase a new one only to find it doesn't fix it.

This is just a shot in the dark, but could there be some sort of a grounding issue? I couldn't spot any mobo supports being used in those photos?

[Mulder]

Thanks for the reply MpG, there is very little metal on the top deck tech station, also there are plastic standoffs supporting the motherboard. I also threw twenty or so sheets of printer paper under the motherboard to make sure that there couldn't be any sort of short.

[MpG]

Ah, gotcha. Couldn't quite tell what material the top of the station was made of, but if there's definitely no electrical contact with the back of the mobo, I guess that's not the problem.

I know there was a problem not too long ago with some G92-based video cards that weren't working with a lot of (top-tier) power supplies, but since the 7900 has the same problem, I guess that's not it either.

My pc is finaly up and running after purchasing a new psu but now I can't get any mice to work in windows. The usb ports does have power while booting(can see the light on the bottom of the mice turn on) but once the XP splash screen pops up all the mice Ive tried turn off. Any help would be appreciated, I would like to use this pc sometime soon. :(

My Bios's USB Intergrated Peripherals settings are

Intergrated Peripherals

USB Controller Enabled
USB 2.0 Controller Enabled
USB Key Board Support Disabled PS2 keyboard have tired it on though
USB Usb Legacy USB Storage Detect Enabled

When you get to the splash screen, unplug your mouse and plug it into a different usb port. You should see some HDD activity while it looks for drivers (standard to XP), and in a minute or two you should have a working mouse. (This is why I keep a PS2 mouse and keyboard around... :) ).
