I have an emachines computer that i got new in 2004, itg has been having some virus and other isssues lately, but i think i will be able to resolve them once i get an external ahrdrive to load all the music file i have on there and do a sysytem restore. the problem is that recently i was tryin to fix a resolution issue and the frequency of the montor got changed. whenever i turn the computer on now, the regular load screen comes up, bu after that it goes to a black screen whhere the message "frequency out of range" comes up. i can't do anything without seeing the computer, so i can't fix the other ISSUES, any advice?Boot into Safe Mode by PRESSING F8 repeatedly at the end of POST (power on self-test) - before it gets to the blank/black screen.

This will start you with the default resolution and VIDEO settings.

Go into your display properties and reset your video to a known acceptable scan rate or auto.

You should now have working display when you reboot.

I'm assuming you have onboard video and are using Windows.  If you are using a separate display card, the above may not work.

Dellthanks, a will try that this EVENING, i am using windows XP and have onboard vis=deo i believe, ios the time i should press f8 while the windows icon is showing and the blue line is running across the screen?If you SEE windows, you are too late. You must hit it before that. Don't be afraid to hit it several times, the computer will beep when it has had enough.thanks for the info, I solved the monitor problem by doing a sysytem restore from safe mode, when other options there didnt' work
