My monitor has lines going across it i don't know why

i turned my monitor on (pc was already on) and the screen had only lines across it. i checked all wires and found no problems. i tried to reboot but now the computer will not reboot. it rebooted on time in safe mode, but will not do that now. it will show the 'windows' screen and then it will run the scandisk where i didn't shut down properly and then just sit there with an hourglass on a black screen. it has a couple of horizontal lines that will scroll up the screen and there are solid black vertical lines on the 'windows' screen and sometimes the colors on this screen are out of focus. this was never present before. i don't know a lot about pc's but i don't think it is the hard drive. again, i don't know a lot. i was thinking maybe the monitor or the graphics card. i tried reformatting the hard drive and reinstalling windows. it reinstalls but still will not boot. i don't have a boot disk.

thanks for any help you can give.

sincerely,

billy

I believe your monitor is the problem

these lines that you seeing can be caused by poor cable connections check that cable connection are snug

if your monitor has a degauss button to eliminate accumulated or stray magnetic fields press it

also check if something is causing high amount of electrical noise

bad fluorescent lights or large speakers have also known to produce interference two monitor placed very close together can also cause problem if the vertical scan frequency( the refresh rate at wich the screen is drawn) is below 60Hz a screen flicker may appear

try using a different refresh rate, to make the change right click on the desktop and select properties from the menu

check control panel display settings to see if high resolution greater than 800/600 with more than 256 colors is selected considers these issues:

the video card might not support this resolution/color setting.

there might not be enough video ramthe added video ram might be of a different speed than the soldered memory

if any of these don't solve the problem consider getting a new monitor.
