Check your memory, pull them out then put them back in. If this dows not work with the case open turn on the power and make sure all the fans are coming on. After this if that doesn work then check the video card. Same thing pull out and reseat. If that doesnt work then try buying a new video card first. Then memory. Then power supply. Unless the power supply doesnt turn on any of the fans or anything then you have a bad power supply and it needs to be replaced

Thin line across computer screen


This might be a mediaplayer issue. Google on EHtray.exe and you will find a microsoft page with a number of filenames related to these kind of problems. Check by pressing CNRL-ALT-DEL and check if you see any of the filenames on the processes tab. Than stop the file and see if the black line disappears.

Vertical green line somthing like an artifact


Your Display cable (inside your monitor) needs to be replaced.

I would look on ebay to try and find the part and then take it to a local tech to replace it for you as I would not recommend anyone take apart a monitor (LCD OR CRT) if you had never done so before.

OR, Buy a new monitor.

Solid line completly across screen, monitor is brand new


Your comp's video card refresh rate (in Hertz, abbreviated Hz) may not be totally compatible with the monitor. Check the properties of your video card, and change the refresh rate (you may have to look around for it) to 60 Hz. This is a pretty standard refresh rate that works with just about every monitor. If it's already there, I'm afraid someone else will have to try and help!

Hope this helps, and please rate my answer, good OR bad.

Good luck!

Mymonitor is black and the on button from the monitor is green and is flashing


i havent seen this question asked, and believe me i have searched. i have compaq presario, windows xp media edition 2005, 64 amd processor, model # SR2017CL, with HP 1703 17" monitor. Prob-put computer in hibernate mode other evening, without turning it off. when i woke up, screen had diagonal lines going across it. i rebooted, well manually restarted, since comp would not respond.
Message comes up white with black writing, essentially, prob with active desktop, restore or turn off. i tried to turn off and screen went back to diag. lines. looks like the horizontal hold of a tv screen is asque. tried adjusting monitor to no avail.
tried a few more times, was fine for a few mins then went to same thing. now when i turn monitor on it blinks red, blue, and so on.
just whole screen that color. so i am at the point where i dont
know if its the comp or the monitor. (i am quite a newby)
ty for any help you can give
