Any v clever I.T. people out there?
Mates PC was playing up with no signal error. Decided to replace his motherboard as it was getting on. Changed the m/b and tested it on an old monitor, perfect. He gets it home and it still shows no signal on his TFT. Have tried 2 different graphics cards, 2 different TFT screens, clearing the CMOS, everything. Stumped completely

EIL I can't beleive I'm reading this as I had exactly the same problem just before Christmas with a 2 day old new PC !!!
We thought i was the monitor (TFT) and it wasn't, thought it was the graphics card wasn't it turned out to be the power supply and before you say it YES the lights were coming on, the PC was booting up but apparently the graphics card needs certain voltage and if it's slightly different the PC can swicth on boot up etc but if GC isn't get the right voltage it won't power the monmitor up strange I know but beleive me it cost me 50 quid to find this out and saved the whole PC being stripped again.
Got to be worth a try and sonuds uncanily like my fault.

Try turning colour and size down to basic stuff.
Could be out of range from one card to another.....in screen display
failing that.....

Stu, thats probably not the problem if the problem existed same as this before the new mobo was fitted, and reading this, it sounds like the problem is the same....
Got me stumped too mate - can't figure it out! Unless it is PSU as Chewy said...

If it doesn't with just the gfx card and board then it could be that or somert else.

The IDE controller etc will be different to what your previous installation was set up for. You can't take the drive with the operating system out of a pc and put it in a nother one and have it work fine just like that!

I have had this a number of times with different PC's here at work and once on my home one. I would also like to say there hasnt been a single fault the same every time.
It has been the monitor (BenQ 17" flat screen) twice, most commonly it is the graphics card slot on the motherboard that has blown, it has also been down to incompatible RAM or in the wrong slot(s).
I have one next to me at the moment with the same problem which is our accountants home PC and it looks to be the actual graphics card this time. The worst part for me is 4 and a bit years ago 60 PC's were purchased including ones for some senior staff, they are all now falling over inc the Servers

Right, it worked fine on a standard monitor. Not a dummy so motherboard was set up perfectly. Not memory, graphics card, monitor, battery, etc. The only thing that sounds plausible is the PSU, so hope Dingy is wrong

is it currently setup to work with your CRT and does it work ok with that?
if so, double check your graphics card settings, if your graphics card is set for a CRT monitor it WONT work with a TFT unless you tell it to before you plug in a TFT monitor, its a catch 22 situation, graphics cards dont always auto detect what you plug in to them.
Ive had this loads of times. By default, CRT is always the default monitor type.
with your CRT connected, set the graphics card to AUTODETECT the monitor, save, exit, swap monitors, reboot
if that dont work, manually set it to TFT, save etc...

ok, so you plug monitor in and it works 100%
you then plug the TFT in and the PC still boots etc. but no display on the screen?
not even when its POSTing etc.?
sounds to me like your GFX card is outputting a signal that the monitor cant display (most common when you try and set a refresh rate of say 70 on a 60hz tft, it just shows no signal
altho HOW you can do that before it even posts (as it should defalt to 60hz on startup) i dont know

jesus dingy, NOW you get the point
when it posts it should default to a a mode any monitor made after 1956 can display
so if it doesnt show the dos looking text stuff then my thoughts of refresh rate are not the cause
get it?
