what tower? model, the monitor has nothing to do with power and dead fans in the tower.
'Sounds, (and silent to) means the PLUS in the PC is dead.
all things can be repaired, that is what technicians do.
here is the chain of events, ! to get noise (fans)
power in the wall 120vac , usa
power to the PSU,
the power button goes to the MOBO, and standby power is there
now and pushing said button the MOBO commands the PSU on
if the PSU is happy (PWROK) thinks PSU IS safe the PSU tells the PC its ok, and power stays up.
and fans run.
so my guess bad PSU, its easy to test with anyf $10 voltmeter,
It is either the power supply or the deflection circuit.
If you can read electronic circuits and know how to use a DVM. Check the power supply voltages and the deflection circuit for any short..
Best of luck. www.aaatvservice.com
Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.
If this is helpful, please comment and rate. Have any other questions, please let me know.
1. check the power cords- make sure all are snug. 2. check and make sure no pins are bent in the cord to the computer 3. make sure that the monitor is not in auto-power save. Or in auto off mode. For example- is the light amber or green. 4. finally, make sure that your settings on your computer are not set to power off your monitor- as in a blank screen saver, power save or hibernate
It happened that to me last year. After 2 weeks of cracking sound symptoms, my monitor begun to blackout - no video signal but the indicator light is still available. I checked it inside using my tester, one of its transistor was burned-out. I tried to replace it and its working up to now.
Possible cause of this is probably overuse of monitor without proper ventilation & cooling causing electronic components to overheat. Since I will not be able to actually check your monitor, the best solution for this is bring your monitor to a qualified TV/CRT technician in your area for proper diagnosis. He's the right expert and the second opinion to that kind of problem.
