Hope some one can help me out here.
The comp specs are: 15" LCD monitor, WinXP Pro (SP1 installed), GeForce4MX, driver used Nvdia forceware 81.98 and default drivers that came with the graphics card.
Currently I have a computer that when it boots up after a while, the monitor would just go to sleep. I managed to figure what was wrong, though how to fix it was the problem.
The problem is that my window is using a refresh rate that is too high for my monitor. Below are what I've done so far:
1) Uninstall gfx card driver (in safe mode) and reinstall same driver (in normal window environment)- Failed
This did not work as during the driver installation when (i think) it was testing for what refresh rate that the card can support (when the screen goes on and off) the monitor would just goto sleep and never turn back on again.
2) Uninstall gfx card driver (in safe mode) and resinstall same driver (in safe mode) - Failed
Although the installtion was a success in safe mode, however when it boots up and about to load the window desktop (right after the window loading screen) and all, the monitor would just goto sleep again.
3) I've tried both the default driver that came with the gfx card and a new version of nVidia driver as mention above in the comp specs. Though both results in the monitor going back to sleep.
How I found out it was the refresh rate was that I used another 15" LCD to test it, on this LCD it gave a message saying "85Hz out of range".
As I understand that in safe mode you cannot change the refresh rate nor can you change it in the normal window environment when no gfx card driver is installed, so what can I do .
Why the refresh rate is higher than what the monitor can support is beyond my knowledge, as this would be one of those days where your computer worked perfectly the night before and would not boot up/work the next day. However this problem had occured before, though at first I thought it would my capacitors or some sort of overheating on the motherboard that is causing it. As if this prorblem occured and I leave the computer off for a while, say a few hrs or sometimes a few days, then the monitor would just go back on again then works for the next month or so with no problem. However this is no longer the case, as it's been almost 3 weeks and the monitor would still not boot up passing the window loading screen.
Hope some one can help ^^
