check the signal cable

By tnyakinye ·
Everytime I start my pc for work it displays the above warning in red with a black blank background. It stays that way for a long time as I keep switching off and on the power. The signal cable is properly fixed. Later it then behaves properly. Whatis wrong?

check the signal cable

Sounds as if it's the normal message from a monitor that does not see the computer as being powered up. Do you leave your monitor powered up without the computer powered on? Once the computer is fully on, the message from the monitor should be gone. If the computer goes into hibernation mode, the monitor may react similarly. You might want to remove hibernation from your computer bios (power management = disable) if these messages bother you.

This answer sounds plausible. But I have already done what it suggests without success.

Hi it is one of 2 things either the monitor energy saving circuitry has a fault or the PC is not booting or initialising the graphics card properly, swap the monitor onto another system and its monitor onto yours and see how they behave at next power on.

Hope this helps

Your monitor is not getting a signal from the PC. You can simulate this by disconnecting the monitor cable, but leave it powered on. You will get the same message.

When you boot your computer do you hear any beep error codes? After a successful POST the computer should beep once. A different beep pattern indicates an error. Is you computer even starting? Do you hear the fan run. Do the floopy and hard drive spin up?

We have several white box (No name) computers which have this problem. We have determined that the clip that holds the processor is weak. Repeated thermal cycles moves the processor and the computer will not boot. We reseat the processor and all is OK.

You may have a flacky power supply that is on the verge of failure, sometimes it provides enough power, sometime not.

You need to determine how much of the normal power up process is occuring. That will give you a clue as to where to look.

This sounds silly, but try plugging your monitor directly into a wall outlet and not through a power-bar. It has solved many of my customer's problems. I still am not sure why...

Good luck!
