Green light blinking very fadley pc will not turn on


Sounds like you might have a partial power supply failure. Try unplugging the power supply from everything. Ther should be a switch on the back that is red and says something like 115/220 just flip that switch over to 220 and wait 5 minutes then switch it back to 115 and replug everything in and then try it. If it doesn't work then unplug everything again and let it sit for about 30 minutes (this resets the power supply) and reconnect the wires and if that doesn't work try getting a new power supply. In partial PCB (Power Supply Board) failures the problem is that trere isn't enough power going to the system to start up so sometimes resetting the PCB will fix it temporary. You should get a new one anyway. that one will fail completely soon. Good luck!

SONY TOWER GREEN LIGHT BLINK


Try to take out the battery on the MoBo. It's a button battery that says CR2032. Let it sit for 2 minutes, put the battery back in and power it up.

Power light flashes till i smack the back of my monitor lightly then it will work for a while?


looks like a loose connection in the monitor better take it to service personnel. and don't smack it cos if the loose cable hits any internal portions of the monitor a big showdown can happen.

take it to a service personnel asap

E Machine T2682 powers up but, doesn't work


This sounds like an overheating problem, that is why the fan comes on right away. When you let it rest, it cools off, and works normally for a while.

Most modern PC's are designed to slow down their operating
frequency when they over-heat, and if that is not enough they
will go into suspend, hibernation or (totally off) modes to protect themselves from permanent damage.

Solutions:
Bigger power supply, more and better cooling fans, improved space and airflow around the cabinet, cool the room with aircond.

also better heat-sinks on the CPU and/or the chip-sets.

all relatively inexpensive.

Power Green Light Flashing HP Desk Top PC m7250n


The 'cure' for this is to replace the power supply.
Inside your power supply are Electrolytic Capacitors. These are Filters for a power supply. To simplify detailing the construction of them, let's just say they are small aluminum 'cans', with an Electrolytic paste inside.

They are used to filter the incoming AC electricity from your house, (Business, school, whatever) They are also used to filter the DC electricity, coming out of the power supply. (Your computer power supply converts AC electricity, into DC electricity)

The one's we're going to concern ourselves with here, are the Output capacitors. The one's that filter raw DC into true DC.

When a capacitor (Of this type) starts failing, it's because Electrolytic paste is developing a gas inside. (Hydrogen gas) The gas expands, breaks a seal, and begins pushing the paste out. (Oozing out)
So much paste loss, and the capacitor can still function, but at a weakened state.

These capacitors deal with the voltage power rail for a power supply. Weak capacitor? Weak voltage rail!

Your processor requires a steady, 'clean', supply of DC voltage. It operates in a very TIGHT tolerance. Too much, or too little, it turns off. Too little it doesn't turn on.

The power surge has weakened Electrolytic Capacitors inside your power supply.
Lights light up. Fans spin. It sounds like the harddrive is running. (It IS! It's just sitting there spinning. More about that to come)

ALL the lights use less than 1 watt. EACH fan uses 2 to 3 Watts. The harddrive just sitting there spinning, uses about 5 Watts.

When it's time for the processor to turn on, (BIOS turns it on), it can't! Processors use 55 Watts to 125 Watts. Depends on the processor make and model.

Your harddrive just is just sitting there spinning, because the processor isn't running.

Solution? Replace the power supply, be happy.

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?

Optiplex GX260 won't boot


I had the same issue and accidentally discovered a temporary solution. Unplug the power from the back of the machine, open the case and unplug the ATX power connection from the motherboard. With the ATX cable unplugged, plug the power cord back in. When you try to turn the computer back on the power light should turn orange and fans should be spinning, with it powered on plug the ATX connector back in. That should turn the computer off. Turn it back on and it should boot fine. You can even shutdown and restart, but when the power is unplugged you will have to go thru the same process to get it back up. This sounds crazy but it worked on mine. Good Luck!
