Last post was Computer will Not turn on but light blinks

Ok, so I unplugged everything inside of the computer to use less power to see if that was what the problem was. It Didn't work but when I unplugged the hard drive, compuer will turn on and go to setup. So it looks like the probem is from the hard drive but now stuck again because what would be causing it not to turn on when hard drive is plugged in?

    Even if I unplug the sata plug and just keep the power plugged into the hard drive, the computer will not turn on. Again it turns on fine without the Hard Drive. I just want to make sure that the problwm is the hard drive because I am going to buy another hard drive and i don't want it to be a waste of mone. Thanks for all your help already.

Power supply in HP slimline s7310n

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!

Optiflex sx280 does not start.

Fans working? Maybe a PSU failure? Replace CMOS Battery. Reseat/replace Memory Mods. It's getting a bit old. Hard to say with a older computer thing start to go one by one. I replaced a PSU after 7 years. CMOS battery dead, replaced, Then the Sound Failed, new sound card. etc. I stripped it of useful parts and sent it out into the world.

Computer turns on, but screen says no signal

Computers send out a video signal.

If the monitor isn't receiving a video signal, you get No Signal on the monitor.

First thing to check is the monitor cable. Cable is used on another working computer to verify, or known working computer's monitor cable, is used in place of it.

I believe we can skip that.

eMachines are budget computers. Designed to save the consumer money, and give the consumer a decent computer.
Problem is low cost of computer, is due to certain hardware components inside the computer, are of low quality.

The Power Supply being one.
Dirty computer inside, also leads to early Power Supply demise.

You can;
1) Test the Power Supply with a multimeter. If you do not have access to one, economical models sell for around $5 to $12.
You will be testing three main voltages;
3.3 Volts, 5 Volts, and 12 Volts. All are DC Voltage.
In comparison two D cell flashlight batteries store 3 Volts DC.

[ Power Supply's are converters. They convert the dangerous high AC voltage (100 to 240. Depends on what country you're in), to the above low DC Voltages ]

Or do you have a KNOWN to be good, Compatible power supply; you can borrow from a working computer?

(I posted this one time, and the person posted back they had borrowed a Power Supply, from their aunt. Computer sat in the garage unused. When finished they returned the Power Supply. Put it back in the computer. Then went, and bought a new one )

Before performing the above, would like you to try this;

Unplug the computer from power. Press, and hold the Power On button in, for 10 seconds. Let go.
Do this same procedure two more times.
Continue also, until the Power On light doesn't briefly flash anymore.

Now plug the computer back into power. WAIT 1 minute.
Turn the computer on. The processor fan, computer case fan/s, and Power Supply fan; should race, (High idle speed), for a few seconds; then slow down. Let's see.

For additional questions please post in a Comment.

Also post the model number of the eMachines. Some examples, T1090, W3653, etc.

Sir, I have a problem with my desktop. when i turn on my system,cpu become on and monitor LED only blinks and monitor not displaying anything.There is not any fault on my monitor.The hard disk LED also not...

Harddrive (hard disk) LED activity light not blinking? Processor isn't operating (Running) then.

Let's try the simple stuff first, then on to more technical.

1) Computer unplugged from power, computer on a table, computer case open.
Follow Anti-Static Precautions, use a can of compressed air for computers, and clean the inside of the desktop computer out.
{ I recommend removing all cables, and laying the computer down on it's side, on a towel on a table.
Open part of the computer case up. Easier to access everything inside the computer}

[ Anti-Static Precautions:

Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

Computer unplugged from power, computer on a table, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

Should you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return ]

Attach the plastic straw provided to the can of air's nozzle.
Break the plastic lock tab off of the top of the nozzle.

Pay special attention to the Processor Fan, and the finned Heatsink sitting under it.
Also shoot air into the Power Supply's case ventilation holes, and try to clean it out the best you can.
When you do, hold onto the plastic straw with one hand, and hold the can of air with the other hand.
If you do Not you risk the plastic straw shooting off, and landing inside the Power Supply's case.

While you're working on your computer, also remove all Ram Memory modules. ('Stick')
Clean the gold plated contact pins with a pencil eraser.
If you are not using a solid eraser, and the eraser at the end of a pencil, refrain from letting the metal band contact the gold plated contact pins.

Refrain from touching the gold plated contact pins. Handle the ram memory module by the Body.
The Body is the rest of the Ram Memory module away from the contact pins.
The Body is coated with a see-through protective plastic }

(You can click on the photo to enlarge)

Rub the eraser up, and down on each contact pin. You don't have to use much pressure, and it doesn't take much to clean each contact pin.
Clean both sides, all contact pins.

When finished use air to remove the eraser dust. You can use air from a can of compressed air for computers, or air pressure from your mouth will be sufficient.
Reinstall all ram memory modules.
{If you have a can of air, you can also use it to clean out the ram memory slots, before reinstalling the ram memory}

Everything clean, and reinstalled, close the computer case.
Plug the computer into power. WAIT 1 minute, turn the computer on.

Still no?
Suggest you test the Power Supply voltages, or if you have an unused computer with a known to be good, and compatible Power Supply, use it for a test unit.

1) IF all of the LED lights were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power. Depends on what Processor it is.

Case in point?
You may have a bad Power Supply with a weak voltage power rail.
Enough power to light LED lights, and maybe spins fans, but Not enough power to turn the Processor on.

Post in a Comment as to the manufacturer name, and Model Number of your desktop computer.
It's on the back of the computer tower next to the Windows product key, or up on the side of the tower.
{Some models have plastic door in front. Once the door is opened the Model Number can be seen}

Power ON/OFF indicator light blinks but monitor will not turn on. Also can only stop blinking light by unplugging the power source to it.

More likely to be bad power supply due to bad caps, open it up and inspect the caps for bulging top/or bottom seals. Post back what you find inside so we can help you further, examples of failed monitors:

Power light blinking

if the power just shuts off for no reason when booted up,it may be the power source is on the way out ,it will work for a while, but keeps crashing, thats the first thing to replace
also make sure you hear the fans working
if it overheats it has a safty shutoff ,
you can also use a house fan, aimed inside the computer while open, to rule out power source

Tower will not turn on

I am in no way an expert on computers but after hours of research, of course starting at, and trying everything short of buying power supply and motherboard, i found a post that suggested to use a blow dryer and blow hot air over the area with the blinking light for about a minute. I was really reluctant to try this but am glad i did. In less than a minute i could hear the comp powering up and the light went and stayed solid, so far that is. I always use for everything and wanted to put what helped me on here in case it can help someone else or save them hours of research. I hope this help some. Good luck.

My 2350 all in one will not turn on.

I'm not sure if this is a solution, but it worked for me. ( who knows how long it will last, but its working for now)

Below are the steps I took:

- uninstalled all the HP drives and software
- unplugged the USB cable from the computer and printer
-unplugged power supply from the outlet and printer
-plugged the USB back in to computer and printer
-unplugged the power supply from the power module. Made sure everything looked ok,
-reattached power supply cord to module ( Made sure everything looked ok,)
-plugged power supply in to outlet ( green light was on)
-proceeded to plug power module connector to printer. ( again, making sure proper connection was made.

* this time the screen came with an error and the "on" power light was blinking.:
This was the error message:



-I proceeded to unplug the power and usb from the printer
-downloaded the lastest drivers and software for the PSC 2350
-After the software was loaded and installed ( I checked the box to install with out USB communication at this point)
- plugged the power and then the USB.
-It came to life at that point. (the computer recognized the "new" product)Going through what I presume were several realignments or internal configurations.

I tested a page, and ran the HP Dinostic's page. Everything checked out, and its running fine for now.

I hope this may have given you some ideas as to fixing your printer.

No power, power supply & motherboard green light blinking

I had the same exact problem for the same exact reason. Plug the power cable into the back. Open up the side of the case and unplug all the wires that the power supply plugs into. The motherboard, harddrive, cd & dvd drives, everything. wait about 10 minutes and plug them back in, plugging the BIG cable that connects to the motherboard back in LAST. This will make the light go from blinking to solid. I think it is a safety? to protect the motherboard from damage.
