My computer did not start when i tryied to turn it on, so i pushed the red butten to the side at my power suply and tryied again ther was a loud bang from the powersuply and ther was smoke comming out from...

The only thing to do at this point is to replace the Power Supply with a KNOWN to be good, compatible unit, and see if the rest of the computer hardware components are okay.

Going by your information stated that the Power Supply is an Enhance ENP-2224B SMPS, (Switched-Mode Power Supply), it is a special shape.

If it wasn't for the Slim Micro-ATX computer case you have, you could use an easy to obtain ATX form factor Power Supply.

From a quick search though it looks like a replacement unit is affordable,

There is simply no way to tell if the motherboard, and/or Processor, and/or Ram Memory, and/or Harddrive, etc., is okay without having power.
Unless you transfer the components on the motherboard to another working motherboard.

If your Power Supply has a rocker switch on the back that lets you use 120 volts, or 220 volts, make SURE it is set to the right voltage.

120 Volts
220 Volts
220 Volts
100 Volts ]

I push the on button and nothing happens. is it


Even though a lot of things might have gone wrong and caused this, especially if where you place the System is not well ventilated, and the CPU becomes very hot, it shuts down automatically...and you will have to wait for a few moments, get a cool environment and power it on. but I will also try and tell you some troubleshooting steps that you can try.

Since you have already checked the power source and all is Ok, then try this out:

Disconnect your PowerPack(Power Supply Unit) from the CPU and try to power your PC with another Power Pack (Power Supply Unit), that you are very sure is working.

If it powers up, then just get a new Power Pack(Power Supply Unit) for system.

If you cant do this yourself, just get a good technician to do it for you.

Try this first and let me know how it goes, so as to know the next step.

Hope this helps.

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).

HP Pavillion won't turn on.

Hmm, did the CA damage any part of it? Sounds silly I know.
And is the power in the, Optical Disk Drive, HDD, Graphics Card and of course on the Motherboard?
Keep it on for about 40 minutes monitoring the heat ever so often even though there is nothing on the Monitor.
By the 40 Minutes it should be mid temp - Hot.
Best of Luck. Tom.

Missing -5VDC and -12VDC

Could be.Some do some don't.Some have a circuit breaker. Take the cover off and check. Be careful though as some parts in the power supply can hold a pretty significant charge for quite a while even after the power supply is turned off.If there is no fuse or if you change the fuse and it blows again I would say a new power supply is in order. Good luck.

Pc no start.........

You might have a bad power supply. If you have a voltmeter, check the voltage of the standby power supply. This voltage is present even if the system is off, plugged in. It powers a small portion of the logic circuit. It should measure within a couple of tenths of exactly +5 volts. If it is low, or high, this will prevent turn-on. The purple wire of the 24 pin connector is what carries this to the motherboard. The color coding layout is found at If by chance this voltage is OK, then check the full on voltages also. Repair of the defective supply is probably by replacement of one or more small electrolytic capacitors in the appropriate circuit, especially if you are technically savvy. Capacitors are available through several suppliers; Digi-Key supplyies Panasonic FC series which are suitable for switching power supplies. Or, you may just replace the whole unit.

Newly installed, first boot up PSU problem

If it's a new PSU, then return it for a replacement...Even online distributors will replace faulty units. And since your old PSU works on it, I'd have to say it's the new PSU that's faulty. Did you make sure that it's the right PSU for the CPU that you have? (As there are PSU units for AMD and seperate ones for Intel...Intel just has a additional power cord to connect to the motherboard)
