Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacemnent from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic - Your PSU might cost you a bit more.
With emachine MOBO's you have to make sure you plug in the 20 pin plug from the power supply to the mobo. Also make sure all hard drives, cd/dvd roms, floppy drives, etc are turned on. Make sure the red switch on the PS is set to 115. Make sure the PS is plugged into a known working outlet. Make sure MOBO is properly in place with all grounds/screws in place and nothing metal near or touching board which may short it out.
You can review the E Machines PS replacement guide here for further instruction.
No beeps are
heard, no CPU fan is turning on, only blinking yellow light. This brand
usually experiences this problem.
First, check the power supply. Disconnect connectors
from the board and make a jumper wire for the green wire to any black
wire. If the PS fan does not spin then it's busted, else proceed below.
Reconnect connectors except the one with 4 wires, 2
yellow and 2 black, then switch on. If CPU fan turns on then you have a
If the fan is still not turning on then check the USB port pins for short circuit.. disconnect it from the board and switch on.
Do the same with other hardware connected to the board.
The metallic casing of computers must be connected to the common ground
of the power utility to protect it from stray currents that result to
damage of sensitive components such as processors, memory and hard
If this is an Atx computer Just unplug it from the external power cord remove the case unplug every thing and remove the screws that hold the power supply in the case. To install just reverse process. If you need more detail let me know.
Sounds like when cleaning your computer, you have also cleaned your processors heat sink and fan. right.
if you have done this then there in lies problem. either your heat sink is not placed correctly or you forgot to apply a new thermal interface material. because once you remove the heat sink the interface material is of no use. you must apply a new one. and check that you have placed the heat sink correctly and firmly.
Your power supply is fried. I had the same problem with my Bestec ATX 250 power supply. I fixed the problem by installing the StatTech model: ATXPOWER250. It was easy to install and works well. It is almost identical to the original but more quiet. I got it for $29 at MicroCenter.com. Also at online Newegg.com, Radioshack.com, Provantage.com, June 20,2009
open the case. pull the 20/24 pin power plug and optional 4-pin power plug out of the botherboard. Remove power plugs from fans, hard drives, cd drives, etc.
unscrew the four screws anchoring the power supply to the case. Slide out the power supply. Put a new one in it's place, the screw holes will line up. Then reconnect the power cables just like they were when you removed the old one and boot 'er up.
All you have to do is make sure the wattage rating of the power supply is higher or equal to the old one. Your old one is only 250 watts. You will have to search VERY hard to find one that low, so don't worry.
E-machines doesn't make particularely powerful desktops so you won't have compatibility problems. Almost EVERY atx psu on the market will work.
yes it sounds like the power supply is shot, you can get a replacement at any computer shop for around $40. i would put in a 400w or 450w that way if you add another hard drive or opitcal drive it wont be a strain on the new power supply
Okay I have found two solutions here. They may both be the same but the information here is kind of vague so I will post them both.
I have found a PS-PS5 power supply as the title suggests. It can be found here: http://www.supermediastore.com/tascam-ps-ps5-power-supply-for-trainer-series.html
I have also found a power supply for the Tascam 424 mkii which can be found here: http://cgi.ebay.com/Tascam-PSP424-Replacement-Power-Supply_W0QQitemZ7405614833QQcmdZViewItem
Hope this helps!
