MOnitor Problem>? Vid Card? I dunno anymore

[xxfilixx]

I just bought a new case and was transferring all my components over. After getting through it all i plug in my monitor to the graphics card and turn on the computer. Fans run lights are on but nothing comes up on the monitor. Checked the power cords and connections all is in correctly. When i unplug the monitor from the vid card it recognizes its not connected to it anymore. Began working my way back from there. Went to the very basics of graphics card, mobo, cpu, power supply and monitor. Still nothing. I tried a new mobo with same cpu, graphics card, and monitor still nothing! Im using: Case- Antec Black Steel, Mobo- GIGABYTE GA-M59SLI-S5 AM2 NVIDIA nForce 590 SLI MCP ATX AMD, Power Supply- COOLER MASTER eXtreme Power RP-650-PCAR 650W, CPU - AMD Athlon 64 X2 6000+ Windsor 3.0GHz, Video Card- GeForce 8800GTS 320MB. Please help, im completely lost after hours of working on this.

OK,

I'm only suggesting this because the very same thing happened to me just a few weeks ago.

I thought I had checked the cables, but turns out I hadn't done a very good job. Try checking the cables at the monitor as well as to the computer.

Did you hear a post? Did you plug in the extra power to the card? (if needed of course). Is the video card seated properly?

Yeah i have tried another monitor also still nothing. Also tried the vid card in another slot but same thing once again.

Edit: Mobo also recognizes when power supply is not connected to vid card, i get the long annoying beep

the only logical step I can think of now is to go and get yourself a cheap video card to test. If you video card is dead, this is the only way to know for sure.

The 8800 GTS is one of those wonderfully bulky cards. I used to have one. Maybe the pins got bent from the damn thing being so heavy ;)
The card I have now isn't much better... in fact it's LONGER.

I swear sometimes I think they just make these huge heatsinks on the cards to make us more impressed with them.

The beeps suggest the POST is indeed running, but video isn't functioning.

You don't mention RAM in all of this.
If the BIOS's configuration settings are set to shadow the [system and/or] video BIOS into RAM...
.
And if that region of RAM is faulty [unlikely to be all of RAM since you get no beeps for the failure of earlier RAM tests], then your video won't function.
Any idea whether shadowing is one of the default BIOS config settings?
If it isn't, you could reset to the defaults [no shadowing?] to see if that produces a fix.

Otherwise, try different known good [fault free] RAM.

Here's that portion of a generic Phoenix BIOS POST:
