"DVI No Input Signal" but connected through DVI and RGB

[Shhhhimon]

I've read through the other DVI problems and none resolve my issue so was hoping someone could?

I was on my computer checking emails, then suddenly my computer screen blacked out. I turned my computer off and on, but when I turned it back on, the screen said "DVI no input signal!"

Sometimes it says "RGB no input signal"

I am using an ATI Sapphire 256 graphics card and an abit fatality AN8 Sli mother board.

I've tried my monitor in my laptop and that works fine, no problems there.

My keyboard doesn't have any lights so cant tell how far it loads. I hear the fans kicking in, but no beep to say that its getting passed the bios or anything.

I use AMD 64 3.2 processor.

I've just noticed after actually looking at the graphics card that the fan on it is not even turning. The CPU fan is turning for the processor so does this mean that it is definately the graphics card thats mashed, or could it be that the mother board is not sending it any power?

Can anyone help?

If you do not get the usual POST completed beep, your system is failing to power up! Open the case and see if any fans start. When you power on, the keyboard lights should flash briefly. Disconnect everything, all cards and memory. Should give series of beeps, for memory problem. If not, is CPU, motherboard or CPU. You will get better advice if you give full system spec, including PSU, make and model.

Okay Guys/Gals, I have been struggling with this problem for months now and have eventually, by a process of elimination, just as I was taught back in PC Repair 101, come to what is for me a working solution.
I hope it works for at least some of you.
I concluded, maybe rightly or wrongly, that, in the case of Nvidia graphics cards, it is the drivers that are at fault.
I have had the annoying “No DVI input error!” warning when booting and then also when Vista had finished booting after the blank screen.
Needless to say, I could never get my monitor to display the actual input it was receiving (i.e. DVI) in Vista 64; XP 32 was OK though, as many people have already stated in this thread.
So this is what I did, though I should say that some of the steps maybe unnecessary, but in the interest of accuracy I will state all the steps I performed.
1. Downloaded and installed Powerstrip.

2. Restart.

From now on ignore any requests to restart until you finish the following.

3. Create and saved a (.inf) file for my monitor by reading the EDID with Powerstrip.
4. Loaded the new (.inf) file through device manager.
5. Stop and uninstall, all graphics card applications, including the drivers, PhysX , OpenGL etc. (Basically everything to do with the graphics card.)
6. Uninstall the graphics card in device manager.
7. Delete the install folders of any graphics card applications.
8. Run a registry cleaner, any will do just use your favourite., I used CCleaner .

9. Restart.
10. Let Vista find and load any drivers it chooses.
11. Restart.
12. Allow the driver installation to finish.
13. Check your monitor driver and reinstall as applicable.
You should now have your DVI connection being recognised by Vista 64.
I know lots of you will want to install the latest drivers to be able to play some games. But like I said, I think the manufactures drivers are flawed.
So I guess you have to make a choice and I know it sux, but if you have the option, then dual boot with XP 32 this is much better for games as has previously been stated elsewhere on this thread.
If not, then you with have to accept you will only get RGB as an input with the manufacturers drivers.
I realise this may not work for everyone and would be interested in any feedback.
