No signal to monitor

If your monitor goes fuzzy or displays distorted images after the unit warms up, it could be caused by a few different issues. Some possible causes include:

1. Overheating: If the monitor is overheating, it may cause the image to become distorted. This could be caused by a malfunctioning fan or a build-up of dust and debris inside the monitor.
2. Loose connections: If the connections between the monitor and the computer are loose, it can cause the image to become distorted. Make sure that all cables are securely connected.
3. Damaged components: If the monitor's components are damaged, it can cause the image to become distorted. This could be caused by a power surge, physical damage or age.
4. Driver or Software issues: Your monitor could be working perfectly fine but the problem may be with the driver or software. Make sure you have the latest drivers installed and try to update your graphics card driver

It's best to try to troubleshoot the issue by checking for any loose connections or cleaning the monitor to eliminate overheating as a cause. If the issue persists, it may be best to take it to a professional for further diagnosis.

This is one of the problems with the wide aspect screen. Most images seem to fit best on the older monitors.
You can go into the video properties and choose one the the display types that best display your image. Unfortunately, by taking a normal (to us) image that looked just fine on an older monitor and displaying it on a newer, wide-aspect monitor, you're gonna distort the image or crop it in a way you didn't expect.
My advice is to experiment with the display until you find something you can live with.

do you mean the processor fan that is located near on the left top corner on the motherboard? if that stopped working then turn of your pc immediately. probably the cpu overheated. if that fan does not work replace it immediately as it will burn the cpu.

Try holding the function key ( fn) and pushing the F4 button. This very well may fix your problem.

hi

reduce the resolution to a bit lower and the refresh rate to a nominal 60hz and things should get back to normal

my hunch is u r using a slightly high resolution and refresh rates

but before that try the buttons on the monitor to see if expanding the image sideways or top and bottom would help initially

cheers
pls rate if this was any help

If the refresh rate is not properly set the monitor may have a wavy or an appearance that lines are going down ... This may also cause a flickering affect.
Distorted or skewed image on monitor. Issue: Distorted or skewed image on monitor.
Cause: This issue can occur from any of the below possibilities.

1. Windows issue.
2. Loose or defective cable.
3. Refresh rate issue
4. Interference.
5. Bad monitor.

Solution: Windows Issue If your monitor has a proper display until it gets into Windows 3.x, Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, or Windows XP please see document CH000121 for software or setting related issues.
Loose or defective cable You may receive a distorted image when the cable is loose or defective. Disconnect the video cable going from the back of the computer and verify that no pins are bent, burnt or broken. Once verified re-connect the monitor cable.
Refresh rate issue If the refresh rate is not properly set the monitor may have a wavy or an appearance that lines are going down or across the monitor slowly or fast. This may also cause a flickering affect. Additional information about how to change the refresh rate can be found on document CH000558.
Interference A distorted image can be caused by magnetic or other types of interference. Verify no speakers, fans or other magnetic devices are close to the monitor.
Bad Monitor If the above possibilities have been checked it is likely that the monitor is bad. To verify this it is recommended that the monitor be temporarily disconnected and then connected to another computer. This can be a friends computer, a work computer, and/or a computer at a service center. You can also help verify a defective monitor by connecting another monitor to your computer. Note: Connecting your possibly defective monitor to another computer will in no way harm the other computer.
