Hi guys. My mom got a new LCD screen from Acer a few months ago. Her computer at the time had Windows98 as an os (comp was purachased in 1998 and has since had one memory increase). On occation the new screen would black out for about a second or two then come back. Then it got more frequent (every few mins). Last week I convinced her to buy the XP Pro SP2 upgrade (not because of the monitor, for many reasons) I was hoping it might fix that problem, but it's still doing it. It's not the screen, because I hooked it up to my computer and it never blacked out. Question is this; Does she need some kind of upgrade for the new monitor to work right? I don't know what video cards are or what they do, does that have something to do with this problem? Thanks to anyone who might be able to shed some light on this and help me get her comp working for her. The XP upgrade fixed everything else that was wrong with it so this is the last annoyance.
