Question about Computers & Internet

1 Answer

Power went out and then my monitor just didn't come on when I turned the computer back on, the blue light on it just flashes like its not getting a signal. I've tried it on another computer and it does the same thing, I've also tried with a different cable plugged in. The monitor is a Samsung syncmaster 931b and is only 13 months old this is the second one that has done this in the last 2 years.

It's possible that your computer froze during sleep. First, unplug the power cord, (with the cord removed) press the power button for 10-20 seconds. PS: You will lose any unsaved data prior to sleep mode. Let me know if this doesn't resolve your problem, might be something major.

Power blue light flashing when i turn the computer on


It depends on where the blue light is. Is the blue light on the monitor or on the computer tower? If it is on the monitor the monitor is having problems and needs to be serviced. If it is on the tower it could be an issue with the power supply.

Your computer has served you bravely and is now wounded in battle.

arfoob43 either your power supply has died or you computer mainboard is toast.

See my published guide dealing with this matter it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!!

To actually fix it requires a bit of electronics skill. First you will have to diagnose the component that has failed and then solder in the replacement component.

Take care

First I think you should do some troubleshooting. Try hooking up your computer to a different monitor and see if there's any display when you boot up. If that doesn't work, then open up the desktop and make sure all of the power connections are solid. One that sometimes comes off is the 2nd motherboard power connector. Because you aren't seeing the blue LED, I think it might be that connector. The motherboard has one 24 or 26 pin power connector and one simple 4 pin connector. The 4 pin is usually in a corner near the processor. Take a look at that to see if your motherboard is getting all of the power it needs. If everything is connected properly and your monitor isn't the problem, the new power supply you ordered could fix the problem. I hope this helps!

Power supplies tend to be either working or not working. I would start with the computers memory, reseating the memory cards (there are plenty of tutorials on the web for how to do this). If the power supply fan was running, chances are you did not need to buy a new one. Does it do the same thing with the new power supply?

Fan is running, power button with blue light is off, cpu won't boot up


Your cpu might have died. As the computer is starting tap F8 and choose last known good configuration to see if you can get it started.

Pop goes the weasel


I agree. The monitor probably blew a capacitor.
Time for a nice new LCD monitor.
