Get a new external carrier, new external drive, or find a power supply that puts out the same voltage and at least the same current. If you cannot find a power supply with the same connector you can cut the cables on the new power supply and the old one and splice the connector from the old power supply on.

BTW please try to put some more specific information when asking about a problem. The more info the easier it is to solve.

No power or light, plus power supply keeps blowing fuse

you have a short most likely on the power supply but could be on the mainboard, inverter board, av/input board. The T-con board is fused and should blow its fuse before blowing the fuse on the power supply. I'm going with a faulty power supply, most likely a shorted Mosfet.

There is a distinctive smell of overheatead transformer. The Psu feels hot to touch. The Cd drive is alsao hot. Is it possible I will need to replace both?

I would try blowing the dust out of them first and make sure the power supply fan is working if this does not help I would replace the power supply first. Also blow the bust out of your cpu heatsink as well

Power supply

Choosing a good power supply depends on a few factors; The amount of power your PC and all it's internal/external connected devices need. The way your PC-casing is built (for airflow).

First it's important to know if you have added any internal/external hardware to the pc since you bought it (hard drives, video cards, usb devices, memory etc.). If this is the case then you definitely need to upgrade, but reading the second and third factors I mention below will shed more light on that.

Second (if possible) you need to check the voltage levels on your current Power Supply via you PC's BIOS or by using a program like Speedfan. If any of the voltages show a reading below what they are supposed to deliver, it means you need a higher amperage on your next Power Supply for that particular line. There are three lines to check (12+, 3.3+ and Core voltage). Usually Power Supplies have a Table with voltages on their sides and on the package. Refer to the one of current Power Supply to see how much amperage your new Power Supply needs to have.

Third it's important your new Power Supply has the fans positioned in the right spots. If your always make sure the air is blowing out of the casing. If it has a small fan on the back, it most likely blows outwards (sucking air from inside your PC case though the Power Supply). If it has a big fan on the top side, it's most likely designed to blow out of the top of the PC case. If it has a fan on the bottom side, it's most likely designed to **** air from the inside the PC casing and blow it through the Power Supply. However it may also be designed to blow out the side of smaller PC casings, in which case the Power Supply is position in front of the motherboard.

Fourth is kind of the-rule-of-the-thumb, always (if possible) buy a brand Power Supply. Generic/Standard Power Supplies do not nearly achieve as much power/lifetime/quality as a brand Power Supply. I recommend a Cooler Master, for their silent but powerful coolers.

Fifth but definitely not a lesser one. Check what connections your PC need. Count the amount of pins connected to your motherboard (usually either 20 or 20+4 pins). Most modern Power Supplies cover most of the connection types. But you don't want to come home with a new Power Supply that isn't going to support your old IDE drives or something.

You could help us help you by providing us with a list of Hardware your computer contains. I can search your PC type and read the specifications, but they don't show what you put extra in/on your machine.

I had a wifi bridge plugged into the USB port. I put too much voltage into the bridge and the PC stopped powering up. I'm assuming I've blown the USB bus on the motherboard?

Try another power supply. Most of the bus is robust enought to handle the current draw but will blow the power supply quickly.
You can get a power supply tester off ebay pretty cheap too.
If you can get your hands on another ATX type power supply, only plug the motherboard plug(s), and maybe the hard drive (without mounting the power supply) and test it.

You are suggested to buy power stabilzer because some the thing which blows the power supply is unbalance voltage. which Power stabilizer resolve . hope fully this would work.

My tower would not turn on when I came home from a vacation. Possible power outage/surge destroyed it. I replaced the power supply, and now I at least get the fan's running, but at various speeds. Still...

Easy Answer, YES MB could be shot.

Heavy dust/lint buildup can cause problems in this area. Unplug all cables from the box, remove the side panel. Remove all accessory cards from the motherboard. Optimally, use a compressed air blower to blow out all of the lint to pristine condition. Don't forget to blow out UNDER the MB too. There is about a 1/2 inch space between the bottom of MB and metal case and lint here can sometimes short between wiring and cause odd power behaviours. Make sure you blow out all of the edge connector slots that the accesory cards plug into. Blow out the power supply as best as you can.

Wiggle all the power supply connectors. Oxidation/microdust can make for intermittent circuits.

Before re-installing accessory cards use the eraser on the end of a pencil to rub the edge connectors until they are bright and shiny.

Re-assemble and give it a try.

If still no start, A bad drive can cause no start and poor power levels. Temporarily install another bootable drive or try booting from CD.

Last but not least. Corrupted firmware on the bios will cause your symptoms. A little known secret of bios systems is that there is ADDITIONAL firmware on most MBs that will boot from FLOPPY and auto install a new bios. You will first have to download the bios update from manufacturer for your MB, then put it in floppy, then unplug hard drives and CD drives then reboot. If the bios re-installs you are ok.

If none of the above works it is time to go to for a cheap MB combo.

Good Luck

Emachines desktop fan runs high speed at power up

I would start by replacing the power cable to the monitor. If you don't hear your hard drive then maybe the power cable to your power supply is bad or you have a bad power supply. So first make sure the cable that goes from the wall to the power supply is good. If it is good make sure the power supply is turning on. If it is then make sure that the power cable from either the wall or your computer to the monitor is good.

What power supply does Lacie 160GB external hard drive use?

Although not sold at Best Buy™, there are available adapters/cables to make this transfer possible. I recommend using a search engine to find "firewire to usb." Hopefully this will give you the results you need.

Emachine power supply

Unfortunately, E-Machines are well known for their power supply problems. I have a room full of them.

Let me guess, you can hear something rattling around in the power supply, right?

When this happens, a component blows cleanly off of the board inside, and sends a voltage spike to the mainboard.

With any luck, the hard drive logic board wasn't damage, and you can recover your data with another PC.
