Your power supply is probably fried. I had a similar 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

Check the power supply first, unplup the cd dcd components and try your pc this way,
Check the cpu fan also as this sounds as if the cpu is reaching critical heat ranga and is shutting down the system to protect it self

    Have you tried it with a new Power supply?

    Try it with a new new power supply!

    If the problem persist after you have tested it with a new Power supply try these steps below:

    Have you tried it with just the keyboard and video?

    Boot it into the bios and check the speed of the fan and cpu temp. (it is very rare for a cpu to die before the mb)

    If the fan is not running at its proper speed try another one,

    (P4's require a min. of 300w and some AMD's are higher to maintain a stable system.)

    Monitor it for several minutes in the bios, watch for fluctuating speeds and cpu temp. changes, if these remain constant with a new cpu fan and the problem persist, It is probaly not the cpu

    The cpu will remain constant in voltage use and temp.(- Provided the fan is good!) If it is good,

    If these do not fix your problem then consider a new mb

power supplies are common failures..a 300Watt ATX power supply is not very expensive these days so it would be an inexpensive way to see if this is the problem..the brown spot concerns me though..seems maybe you have a filter in the supply that may have leaked electrolyte...if you have another computer with the same type of supply in it..you can try it..as long as the plugs are the same and the wattage is the same or higher

I have a bestec atx30012z and the power turns off after a few seconds of turning it on.


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 replacement 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

EMachine T6420 will only turn on to start the fans and then immediately turns back off - has Bestec ATX-300-12E power supply - do you think that's the problem


These computers have had problems with the mother board. I had one the same problem, and I did research on the INternet. Best advice.... find a replacement board which will fit this box. Then you will have to re-install the operating system with the cdrom. You may be able to repair the system.
More than likely the power supply is not the problem, but the board is suspect more than anything.

Upgrade for Bestec ATX-1956D (HP p/n: 0950-4106)


How about the LC Power LC350M Micro ATX - 380 Watt

or the 

Logisys 350W Micro ATX

They should fit your form factor and output as much as 350W being relatively cheap, but neither gets 18 amps on 12V rail...
I think no power supply of that size has an output like that...think about a cheap but substancial chassis upgrade if you need that power...Have a look at directron for the PSUs.
