"NO SIGNAL" - this is driving me nutts!!

[tinypilot]

I should perhaps post in another forum, but I am not sure if it's a monitor problem or something completely different..

The problem is that my monitor sometimes shows a "no signal" when booting into windows or after a restart, it's like the gfx doesn't send a signal from time to time. Normaly when the screen is black in the boot reach Windows it will recieve a signal and power up.

I first thought it was a DVI-DVI only problem, but I have also seen it a couple of times with DSUB-DSUB. I have changed cables but it still happens.

Re-installed windows and same thing happens.

Changed PSU, GFX and mobo - not luck with that either.

Is there some stupid setting in bios that I should know of, I simply have no clue..

The old system:
Asus P4C800E-Deluxe
P4 Northwood 3.2ghz
Chill Innovation 500watt psu
Asus 128mb 6800gt
Corsair 3200LL pro 1gb / 2 sticks
Viewsonic VP201B monitor

The new system:
DFI Lanparty SLI
Asus 7800GTX
Hipe 520W psu
Corsair 3200LL pro 1gb / 2 sticks
AMD X2 4400
Viewsonic VP201B monitor

Any clues?

Monitors lose their signal when the display adapter is powered down. It should see a signal again when your computer POSTs, but it might take a bit for your monitor to "turn on." If you have an LCD, it's usually instantaneous. If you have a CRT, it can take a few seconds, which is probably the amount of time it takes Windows XP to load.

Try accessing your BIOS at startup, and see if it appears on the screen.

It is a LCD screen and yes it should do it instantly, but sometimes the computer can do all the post stuff and not before the Windows load screen will the monitor kick in.. It's like the gfx card isn't sending a "known" signal to the monitor or something. Works a lot better in analog compared to dvi-dvi but it does fail in analog as well.

Other ideas?
