Specs: Any OS
My Problem is actually OS neutral. I face the problem just before the operating system loads. The native resolution and refresh rate of my monitor is 1600 X 900 and 60HZ respectively. My mother board is Gigabyte G31 with integrated intel GMA 3100. I also have a Nvidia 9400GT graphic card with 1GB Ram. The monitor is connected to the Nvidia graphic card via a VGA cable.

My problem is as follows. When i put on my Pc the (~)first screen on the monitor is the Graphic Card information output such as the name and ram size. This screen does not look legible.

After this the there is the bios post and booting up screen this looks alright. If i press delete and go to the bios setup screen the (~)screen once again does not look legible.

I have setup my pc for multiple booting of os. The (~)screen for choosing my os also does not look legible.

However once the any os boots up the screen once again becomes legible.

After reading the information menu on the monitor through the buttons on the side of the monitor i have come to know that the above screens are not legible because the refresh rate changes to 70HZ during the screens marked as (~) above and the resolution also changes.

I am facing this problem for the past 15 days. Before that this problem was not there

I would therefore appreciate if someone would tell how the reason why the resolution and refresh rates became illegible for my monitor and how to fix it. There are no buttons on my monitor to change the resolutions and refresh rate.

I have already tried the following:
1) I deactivated the Nvidia card in bios settings and connected the VGA cable directly to my integrated VGA port of my motherboard. But this did not fix the problem.
2) I also uninstalled my nvidia drivers and then reinstalled it but to no avail.
3) I also installed the intel vga drivers but still no use.

Thank you for reading patiently.

The fact that it happens BEFORE windows loads (splash screen, BIOS menu) & happens with both the Intel integrated & 9500GT (yuck) seems to indicate that the problem is with the monitor itself. Try it on a completely different system & see if the same thing happens.
