I started having a problem with the computer saying it was low on memory when in fact it was not. I checked the resource manager and found the computer had a lot of modified memory in use so I looked this problem up online. One of the solutions was to go into the bios and enable memory remapping. Mine was already enabled so I thought if I disabled it then enabled it that it might work but when I hit save and exit the screen shut off. The computer stayed on and if I turn it off and turn it back on the computer and the fan come on but the monitor doesn't. I know that's not the problem because the computer is hooked to the tv and it is working fine. Did I cause this or was it already going out? Please help I have everything on this computer. Thank you.
