The best thing when you can't see power going through your computer is
1. check the obvious once again (the current setting in the back of the ps.. is it 115??
2. replace the powersupply for known good powersupply.. if it works, your powersupply is defective (likely) if it doesn't your motherboard (unlikely), your memory (likely) or your cpu (unlikely) maybe the one defective.

My pc desktop wont work its my tower cuz i tried the monitor on a different pc so what could it be


I would think it is either you motherboard or your power supply. I would start by looking at the power supply. You can pick up a tester at any electronics store. Even at that most of the time electronic stores will test the power supply for free. If it isn't that then I would check out the mother board.

New power supply does not work...is it the motherboard


well there are two ways to to figure out which item is broken first you can hook up the power supply and test the pins in the plug with a voltage tester to see if it has power. I do not recommend this approach if you are unsure of what you are doing the voltage coming from a computer power supply is very dangerous. the second thing you could do is attach a different power supply to *********** board if ti works the mother board is good and it your power supply that is busted. Also make sure to check the back of the power supply and make sure it is set to 110 and 220 voltage because this can cause your power supply to not function correctly. It will be a little red switch on the back that says 110v on one side of it and 220v on the other.

I hope this helped.

Thank you,
Norse

1. Could be as simple as not having the Power Switch on the right jumper...double check.
2. The board will power up with nothing hooked to it... just power, CPU, MEM... disconect everything to just to get the board up to the bios.
3. Make sure PS is securly connected to the MB.
4. Check Jumper on the Board to make sure the Test Jumpers are not set
5. Memory is seated correctly... if you pull them out the board will start and beep...

Do you have a diagram that would show me step by step how to install the new power suply I bought for my computer.


Their is really no diagram to show you how to hook up your supply.
You only have a hand full of plugin connections.
Your 24 pin connection to the mother board, you may or may not have a 4 pin 12 volt video connector, which has to be connected if on the board., and your fan connections.
Everything else is controled thru the motherboard.

I have a hp pavilion 513c it wont boot up! the


Hello,

There are only two ways this can go for you.

One- you need a new power supply

OR

Two, you need a new mother board

You can verify the power supply by checking it on another machine

If the power suppy is good

And you do not hear the bios beep- then you are looking at a new motherboard- I would double check the powersupply first- most stores that sell them will let you check before you buy a new powersupply.

I bought an All-in-One Multifunctional Converter (Coolmax CD-350-combo) to transfer my data from my non-working laptop to my new laptop. The problem is that it doesn't fit into my hard drive. My old laptop...


I have spent hours trying to figure out how this damn thing works since the instructions require the user to have way more computing skill than I. First, the thing comes apart, one part being the interface and additional power supply and the other being the power supply that may connect to the Coolmax or your HD power supply if not operational through the Coolmax. If your old HD is larger than 3.5", you may have to connect the power plug to the HD 4 pin power source. otherwise, connect old HD to the Coolmax CD 350 adapter and then connect the Support USB2.0 to a USB interface on your new computer. If your old HD is a 2.5 SATA , do not connect the red power plug to a USB2 interface on your new computer unless you are positive the old HD operates over 5V. Connecting the red USB power source to your new computers USB2 interface may cause the old HD to shoot sparks and smoke, and you will not need the device any more.

New power supply problem


One of the reasons that this could be is that the power supply doesn't have enough power to power everything. Trying exchanging it for another one that has more watts. If this is an exact replacement as far as the wattage goes, then your problem may lie else where, and you may want to take it to a reputable local computer repair shop for further inspection.

New Computer Wont Boot!


when you say "the fan makes a noise like its getting ready to spin", which fan...power supply's or cpu? if you answer power supply, then the POWER OK signal is not returning to power supply and it then quickly shuts down to prevent further damage. double check a firm connection to mother board. If you answer CPU, then it becomes far more complicated. Try re-seating the memory chips.
