I believe I've clicked on something that is keeping my monitor from coming up. I click on the monitor and it says that test good. I was first having trouble with message "Trouble finding operating system". So I went into BIOS and I think I clicked something about PCI and after that monitor will not work. Well now how am I suppose to fix the problem with monitor when I can't see anything. Please help. Desperate. Been 2 days with computer. Having to work on laptop which I hate.
