Hi Computer Master.....My computer froze, so I unplugged the cord from the back of the CPU, and plugged it back in. I went to press the button in the front of the CPU to turn it back on and nothing happens. I took the cover off, and when plugged in, I see a little green light inside that comes on, so it must not be the power cord. Do you have any ideas? Thanks Jim

Re: E Machine CPU
I have seen systems where when they get an unexpected shutdown such as a power failure, then the power supply will not supply full power when you try and start back up. I would suggest that you turn off the power switch to the power supply (if you have one), what a few seconds and power it back on.

It sounds like the CPU is over heating. It probably has poor ventilation. Unplug the unit and open the side panel. Carefully vacuum all the dust inside. Be careful not to damage any electronics. You can use a small brush to loosen the dust before vacuuming. Good luck!
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.
You need to plug in your CPU fan. The CPU fan is VERY important in that it constantly cools your processor, making sure your computer doesn't over heat. If the computer runs and the fan isn't running, the CPU will over heat and cost you hundreds of dollars.
Turn off the power
Unplug your computer
Open up the case of your computer
Find your CPU fan
Find the cord coming from it
Find the plug on your motherboard labeled CPU fan
Plug it in there
Plug your computer back in
Turn it on
Could be power supply, unplug every thing from the board, remove all drives, cards everything but the mem. turn it on, if you get some beeps, add your Hard drive. The power supply may not have the guts it take to run all the peripherals it used to, this test will tell you if its the board or power supply.
it simply means that your cpu is not giving back signal to your monitor to process, in fact, it is a cpu problem that is why there is nothing to display in your monitor.
Your cpu froze because of that usb thing. the only way to unfreeze it is to manually reset your hardware in this order.
1. RAM modules. If you can unplug your RAM (memory modules) connected in your motherboard, please do it. Just unplug the modules and then plug it back in. if you have 2 rams, then interchange them when plugging it back. this will force your mobo to refresh its resources.
2. CPU. if you can pull out your cpu chip, then do it. this will refresh your cpu setting in your mobo. (mobo = motherboard)
You may need to replace the cmos battery, its a cr2032 3v button cell Make sure all your expansion cards and memory are reseated. Make sure all cables are reseated. your power supply could be bad
If that doesn't work try this
Here is my fix for the dell dimension 4400 amber light problem. It works! replace cmos battery. then unplug power cord form wall about 5-10 secs. then plug it back in, wait 5 secs. If amber light comes on, press and hold power button until it goes out.
light out, press and hold power button while amber light comes on and
goes off again holding power button 2-3 secs after light goes out.)
repeat whats in parenthesis until computer turns on it should only take about 6, 7 tries.
After the computer boots, you may want to setup cmos or boot into windows. After you shutdown, unplug power cord for 5-10 secs then plug it back in. Press and hold the power button, computer should come on. I found that's the only way to turn on the computer. If you shutdown and don't unplug power cord the computer may not boot, mine didn't. Strange I'd say
Turn power off and unplug power from computer.
Unplug printers,backup drives and speakers.
Open case and unplug power supply from the board.
plug power cord back in press the power button.
Of course nothing will happen.
unplug power cord again.
plug power supply back into the board.
plug power cord backup and press power switch.
If nothing happens unplug power cord again.
pull out your memory sticks and plug cord back in and press power button.
Of course not much will happen.
But really something is happening to your computer so continue.
Pull power cord and replace memory sticks.
replace power cord and press power switch.
Continue this pulling out pci cards one at a time until you find out what the problem might be.
Try different keyboards and mice too.
This might work. Unplug the power cord connected to the back of the PC. Press & hold the start button on the PC case for ten seconds. Reconnect the power cord & try starting the PC. Still no power. Connect the power cord from the PC directly to a wall jack. (No power strips). Still no power? Possible the power supply went bad.
Inorder to verify that the problem is with the monitor have you tried the monitor with another CPU could you please try it because it might be a problem with it the signal may not be reaching with monitor
