Personal computer help? Options

[creole]

There is a weird problem going on with my computer. Most of the time, the screen will have a black bar near the left or right and the screen itself would be misaligned. The only way I could fix it is by Right Click > Properties > Settings > and changing the screen resolution. Any other way to make this stop?


Another thing is sometimes my computer screen just freezes and bunches of colored lines would stretch the whole screen. The only way I stop this is by turning off the computer and hope it doesn't happen again. Any suggestions?

are you using a crt monitor? there should be a default resolution that the computer uses. just find the one that looks best and leave it. but if it isnt a laptop most likeley there is a menu on the monitor. just click the menu and play around with the settings. and change the width. but changing it to a better monitor makes more sense or else it will be stretched.

think of it like this. square monitor, 100x100. so if the resolution were 50 wide and 100 high there would be bars. that resolution of course doesnt exist though.

and does anything trigger the lines? if not then it may be overheating. make sure the computer has room around it and no vents are being covered.
