For example in XP to 7 I could check the screen resolution. Usually I boot safe mode and set it to 800x600, ok that and reboot. Then again it may need a boot like we read at http://support.microsoft.com/kb/310560
<span id="INSERTION_MARKER">Okay, I've had my computer for two years, and over the years there have been minor problems, but nothing I couldn't work out how to fix within a couple of days, but for the past month or so my computer kept randomly shutting itself down, then a few days ago it when I tried to log in in normal mode the screen went black before the log in screen came up, although the noise to log in still came, and everything else seemed to be working fine. there's nothing wrong with the monitor or the connection, as in safe mode everything works fine, it makes one long beep, then two short beeps when i first turn it on, which I believe means it is a video adapter problem? I have tried replacing the ram, and nothing changed, I tried clearing out the dust, nothing changed, I tried running a virus scan all clear, I tried re setting the whole computer, and still no luck, so please, please help me? I have no idea what else to do???
