My monitor won't start up when I boot my computer, there's a bit of a story so I'll start from the beginning...
About 3 - 4 months ago my monitor started playing up, when I booted the system the screen would be jumping, so I turned my machine off, tried again still the same thing, tried again a couple of days later same thing. I left it for about 3 months and came back and turned it on again, it worked. It worked for about a month with no problems.
Then today I turn it on and I don't get any output on the screen at all, but the computer is working, everything in the case is ticking over and making little noises like it normally does. So I turn it off and back on a couple of times. I check that everything is plugged in securely and the video card is in properly, it still doesn't work.
I thought maybe it was the monitor, so I got another monitor that I know works (plugged it into another computer) and it didn't work as well, so not the monitor. Then thought it was the video card, I have a pentium 3 and I have some olf pentiums lying around so I went and grabbed one of them video cards and plugged it in to my P3. I booted it up and it worked the first time, it booted into windows and everything, then it comes up with a blue screen that doesn't have any text on it and didn't do anything, so I restarted. Then the screen was blank again.
After countless times of rebooting the machine and checking everything was in it's place securely and plugged in properly it suddenly works again!
But now it hasn't worked again since then, I had to restart that time because I hadn't plugged in the mouse and couldn't do anything like check settings and such.
So if anyone has any ideas of what could be wrong I'd be so grateful to hear them! I really need this computer to work! I wouldn't be surprised if there was something wrong with something else in my computer because it makes a lot of chugging noises quite often, like something is about to die in there!
