I have had this computer for almost 5 years and this is the second time this has happened. This is much worse this time and I dont remember what I did to fix it last time. But anyway, there are horizontal lines across my screen all of a sudden. It looks like an old tv attached to rabbit ears. I hate it and I want it fixed fast. Any ideas? Ive already tried the obvious with the unplugging, the leaving it off, uninstalling all the drivers and reinstalling new ones...

Re: Lines across screen
The screen you have is almost certainly on the way out. This type of fault is in the Horizontal Flyback section of the Monitor. Usually components fault or age and change value, these lines are normally "Turned Off" so ya can't see them, that "Turn Off" circuitry is going faulty.. it will only get worse. I suggest a new, or 2nd hand monitor as they are so cheap these days fixing CRT monitors can be cost prohibitive.

How to Tell If A Computer Monitor Is Going Bad
Computer monitors are designed to work properly for years.
Whether it's from a defective part or power surge, they go bad eventually, and you'll probably know it when it happens.
Look for vertical or horizontal lines across your monitor screen that shouldn't be there.
Time how long it takes for your computer monitor to come out of sleep mode. It shouldn't take more than 5 or 10 seconds for the screen to be fully operational when taken out of sleep mode or turned on after being turned off. If the screen is not operating as quickly as it should, it could be a sign it's getting old.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
it sounds like you have a small crack on your screen that has gotten worse over time, these black areas are where the lcd crystals aren't active anymore, unfortunately there isn't allot you can do apart from buy a new screen or put up with the black lines.
When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.
The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.
If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.
now if you can replace them your welcome but i wont suggest that , cause you may break it more....!
any ways do comment if it helped you in any manner!
Replace it, it is going bad. I could tell you what would cause this such as bad driver IC etc. but bottom line is its five years old, you got your moneys worth out of it so bite the bullet and get a new one.
Get some freeze spray from radio shack then
try placing a little spray on each chip on the
video board and power supply board and each time you spray a chip look for the picture to clear up. When the lines go away you have located the
