I was trying to free up more ram...by decreasing the shared ram or aperture size in chipset inside bios, and i set one to 0 mb and other to 32 mb (Both at their minimum) since then there has been no display....please help...i am really struck...btw my pc specs are 512mb ddr ram, 80gb hdd, and asus kvm motherboard with 64 video ram size. I dont have much knowledge about this...and i need urgent help... :doh:
It sounds like your video is integrated onto the motherboard. In almost all cases, integrated video uses part of the system RAM. The apeture size won't really affect anything, but the shared memory does. When you set that to zero, you effectively disabled the display. What you can do is reset CMOS; this will set your BIOS configuration back to the factory default settings. Do this either via the clear CMOS jumper or by removing the battery on the motherboard for about 10 seconds (more won't hurt anything, but too short of time won't clear things). Make sure to unplug the computer from the wall before you do this.
Yup, your data is safe. If resetting BIOS does screw with your data, then you've got some major issues.
