If i put a 110v powersupply in a 220v electricty and burned it would it have effected what its giving electricty to?

While most modern power supplies can handle such a mistake with minimal damage to the motherboard and attached computer components, there is still a high probability that you damaged a component on your computer.

The only surefire way to know if you caused damage is by testing; so it is suggested that you obtain a new power supply, set it on the proper setting, plug it into the machine, and see if it all still works. I'd run some stress tests (there are utilities that can do this for you, or you can have a local repair guy do it), and see if the machine is having any issues.

The most common components that are damaged by a power surge are:

  • Memory
  • CPU (processor)
  • Motherboard
  • Hard Drives
Those are the most common to fail. If you use a new supply, and notice your machine does NOT turn on, chances are, one of those devices is burnt or damaged as well. It is suggested to test them in turn, to see where the issue lies.

Engine surging - Hyundai Lantra 1.6 GLSI auto est. 1997

You need to check out your voltage and charge regulator. Some are built into the car, and some are external. Check your fuse and relay boxes under the hood for anything blown. You are is not regulating the charge your alternator produces. Whoever installed the alternator is responsible for the charge function working. If you took it to a mechanic then they are supposed to finish the job. Otherwise go to your local auto parts store. Ask them too look up a voltage regulator for your model. Some people don't know how to use that system so go a couple of places to make sure you find someone who can really find your part. When you find the part you can either replace it (recommended) or use a OHM meter to test resistance on both new and old one. If the values are different, then replace the regulator. Let me know if anything in this car is much different than that.

Lightning storm & power went out for about two seconds. PC plugged into surge protector but would not go back on. Found that surge protector blew and was no good. Got another and plugged all back in...

Your reasoning about the switch mode power supply being damaged is probably right.
Bear in mind that this power supply may not be the only thing that may be damaged in your computer.
You won't know for sure until you borrow a power supply and install it into your computer to see if it will work again.

No power comming out of any of the conectors

Sounds like a blown fuse. You could replace that, but opening the power unit will void your warranty and the unit itself might be damaged as well. My advise would be to buy a new one unless you really know what you're doing, a half-broken power supply could damage other hardware or even start a fire (worst case scenario).

I have the same problem with Demension 5150. Replacing the P/S didn't solved the problem. When I connected the P/S the motherboard green LED light lighted up, however, no matter how many times I pressed...

For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen. The PC may not boot to windows, but it Does post at this point, and with that the problem is resolved. If windows does not load, then you have a new problem. Best dealt with asking a new question.

Good luck!

i don't know how much expertienc and the amount of confert you have doing this, but anyways, try taking your motherboard out of your case, and find the front panel headers(usally near the bottom right of the board, find the one labeled as pwswitch (or something similar) and use something to short the two pins,. nothing else while having CPU Powersupply ect,. or if you have a spare power button/case try that as well, if you can't fighure it out, DO NOT TRY IT and contact me and i will see about getting a picture or something

Best of luck,
P.S. if this works then don't forget to rate me, if it doesn't work then contact me and i will see about something else(don't rate me until it is fixed or i give up(

Disclaimer: By trying this you herby release me of any liability If anything happend due to user error i assume no resonsability for injury to self, others, home or property. If you do not feel confertable doing it, DON'T, then contact me
