Can't install power supply


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


Unplug all electronic cords connected to the computer.

At no time during the installation should any cords be connected to the computer.


Remove the screws holding the computer cover case, and remove the cover case.

Locate the computer power supply box, which looks like a large box out of which a bundle of wires run and connects to the power cord jack on the outside of the computer case.


Unplug the power cables from the internal devices connected to it.

Be careful not to damage any of the sensitive control boards or devices inside the computer, and be certain to remember write it down if you need to what devices will need reconnecting to the new power supply when you finish the installation.


Unscrew the power supply from the inside of the computer case and remove it.

Check the original power supply's red voltage switch for the correct setting.


It should read 120 or 240 if you live within the United States.

Confirm this setting as the correct voltage setting for your power outlets.


Make sure your new power supply gets set to the correct voltage setting before you install it.

If it cannot be set to the correct voltage, do not proceed with the installation or you may damage your computer.


Return the new power supply and buy one that is compatible with the voltage requirements.

Install the new power supply, reattach the screws that will hold it in the proper place inside the computer.


Reattach the power cables that come from the new power supply to the devices that were connected to the old power supply.

Make sure all of these connections are firmly in place before you turn the computer back on.


Reattach the computer power cables and all the cords connected to the computer during normal operation, but do not close the computer case yet.

Keep your hands clear of the inside of the computer case as you attach power cords and peripheral devices.


Turn the computer on and observe the performance of the computer without touching anything inside.

Do all the computer fans function normally?


Does the computer operate as well as or better than before?

If you feel that the computer behaves normally and you do not encounter any problems, turn the computer off, remove all the power cords and peripheral cables once more, and close the computer case.


Then reattach the power cords and peripheral cables and begin using the computer.

Check for errors if you encountered any problems starting the computer or if it would not start at all, unplug all the power cords and computer cables connected to the computer and look inside.


Make sure that you connected all the correct power cables inside the computer securely and did not miss any.


If you have confirmed this and the computer still doesn't start or operate normally, call your computer manufacturer or a professional computer repair shop for assistance completing the installation.

Most power supply units will fit

Like everything else in our high-tech world, power supplies come in myriad sizes and shapes
you should check all the electrical connections before you make a decision and make sure they are the same as the ones that you will need to run your computer also

Check the measurements inside the frame to make absolutely sure it will fit,

I have a Dell Dimension E510 and was told the Radeon 4670 would work in it. I installed the card but the computer just goes on and off and on and off. Is the card too powerful for my computer? Or do...


You do need to install the drivers before using your new card, but that would only effect the display if you didn't. If the computer is actually shutting down, then I think your power supply might be the problem. Check your card's manual to see what the minimum power input is. Then compare that to what your current power supply's output is. These new cards draw a lot of power and if your power supply can't handle it, the computer will shut down. If it does turn out you need a more powerful power supply, you can find them online. It's a fairly easy change to make. Hope this helps!

Need a new Iso-350


Please clarify? tennis rocket? industrial standard? switching power supply? safety glass panel? all of these are ISO-350...

I assume that you need new computer power supply, as this is just standard 350W switching power supply, this can be repalced by virtually any availbale on the market power supply as long as it is of same or greater value. Nobody is actually manufacturing 350W power supply, I would suggest any available computer power supply will do fine to replace that one.

Size of the power supply is standard, therefore it is irrelevant how many watt is your output as long as it is greater than 350W.

You can find abundance of 400W power supplies on e-bay in price from $0.99 + postage. Your local computer store will have them in stock, if you have access to second-hand computer, you can remove power from it and replace as well.

Hope this help solve your problem.

I have a problem with my pc it will not boot up it starts to boot then just turns off I cant get and diag done to troblem shoot the problem PC specs Win XP sp3 3gb ram DDR2 Celeron D...


now, this sort of shut down is difficult to diagnose on remote, i would suggest downloading your motherboard manual beforehand. before you do anything, i would suggest read in manual where is reset pin and how to reset bios to original state, but do not do that yet, it will lost all your mods settings and return m/b - bios to original state. there are several possible causes of that fault.

1. faulty memory stick
2. thermal or fault on power supply
3. thermal or fault on motherboard
4. corrupted bios

we will start with easiest to check re 1.
a. switch off your computer,
b. remove power cable from power supply,
c. remove side wall,
d. remove memory sticks and replace them with known working ones from another computer
e. reconnect power supply and switch computer on, if computer works correctly, you solved your problem and need to replace memory sticks

power supply is not much more difficult re2.
a. switch off your computer,
b. remove power cable from power supply,
c. remove power supply cables from motherboard and all accessories, do not remove power supplly from it's craddle yet
d. connect cables from new power supply to your motherboard and processor fan, connect them to your hdd and cdrom,
e. connect power cable to new power supply and start your computer, if computer run correctly, switch it off, remove old power supply and replace with new one

most tiddly bit... when you arrive here that meant that previous two did not solved your problem, re 3:
a. switch off your computer,
b. remove power cable from power supply,
c. disconnect all cables from your m/b
d. connect power supply to m/b and processor fan
e. connect ps2 keyboard
f. connect monitor if "all in one" m/b, video card and then monitor in any other case
g. insert power cable to power supply
h. switch on your computer
i. acess bios (that is usually done by tapping "delete" key, find in your manual) if possible, if not then:
i1. switch off power supply
i2. remove power cable from power supply
i3. re-set bios (you need to locate reset pins/switch/button on you motherboard in manual)
i3. reconnect power supply cable \
i4. switch on the computer
j. acess bios and set your thermal to 75centigrade or 80 centigrade and 5min
k. close bios saving changes
l. re-boot your computer and leave it for 10min, if computer still run, that will indicate your problem lies elsewhere.

checking auxiliaries:
a. switch off your computer,
b. remove power cable from power supply,
c. connect cd-rom
d. reinstall power cable and re-start your computer
e. allow 10min run and check if computer is still running

switch off. remove cable and connect your hard disk drive, run or switched off? if off, you need to check your hdd...

any other auxiliaries need to be connected again in steps and if finaly you find one which terminated boot up, this meant that this particular element is responcible and need replacing. you need as well consider that your power supply maybe perfect on the bench, but will be too small for load required adn simple upgrade to more powerfull mother board can solve the problem.

hope that half book on problem solving solve yours :-)
