Page 1 of Mega annoying pc problem!

I`m not sure if my problem is to do with my tft monitor or graphics card.
When my computer is starting up it displays the message "out of timing". It has been doing this for a while and now won`t boot into windows at all.
I had the problem before with my radeon 7000 and had to reinstall windows which seemed to stop it for a while. I have now replaced the graphics card for a radeon 9200 but the problem is still there. It has slowly been getting worse up until last nite when it wouldnt boot into windows again.
I`ve tried reinstalling windows today but this hasn`t made a difference.
At the moment I`m running from my onboard graphics card and there doesnt seem to be a problem but the onboard card is poor to say the least.
What is the problem? Is it windows, graphics card or monitor?
Please someone help me, I`m goin out of my mind!

Hi,

are you trying to push the TFT at too high a refresh rate?
have a read of your TFT`s manual to find out the optimum
refresh rate and resolution.

this maybe why it`s ok with the onboard graphics, seeing as
onboard is less powerfull than the Radeon.

Ste.

...is that gasoline I smell?
