Hi Bad news. your motherboard has been fried. You could try refashing the BIOS but I've got $10 dollars to your one that it wont work. Best bet - keep the tower, keep all of the running gear but a new motherboard and prosessor are in order.
Glad to be of help. Good idea thought would be to get a decent power board that also supports internet connections. "sacraficials" only cost about $50 AU but you can get decent resetables for around $200 AU. Less tears and angst.

    if you have beeping sound
    Usually a memory card or a hard drive that isn't plugged in all the way.

    hi, have you tried changing the fuse in the mains plug and checked all the leads are in the back of the computer properly.
    Once this is done then try switching it back on check for the fan starting up if you have changed the fuse and still here nothing then the chances are the power pack has blown. 
    These can be brought and are easy to replace as this is the most likely cause of the problem. 
    Also if you take the case off before you switch it on then look on the board and see if their are any led lights lit up their should be a couple for the modem etc if not the the power pack has blown and will need replacing these can be brought for next to nothing from any computer repair shop.

    As for everything that is saved and all the files you need these will be saved onto the hard drive which can be removed and put into another computer but replacing the power pack will solve your problem.
    Make sure you change the fuse in the plug as it sounds like a power surge has tripped your computer out so unless its blown the fuse in the plug then you will need to replace the power pack which would be the cheapest option.
    But if you didnt want tto do this then remove the hard drive as this has all your files and all your saved files on it then this can be easily put into another computer giving you acess to all your files.
    This is also easy to do and something you can do yourself as its only two block connectors that go into the back of the hard drive you remove these then remove the 2 or 4 screws running along side the hard drive then put this into another computer remove the hard drive your not using and put yours in place then it will be exactly how your own computer was in the first place.

    Let me know if you have any problems and ill be glad to assist you further ok

Try unplugging th power cord for ten minutes first, if that does not fix it there is an internal fault, maybe the RAM or the motherboard.

    Ensure that there is nodisk inside the computer , if there is a CD/DVD remove it.

    Unplug all USB cables , and start computer with video, power, and mouse / keyboard cables only.

    Try unplugging the power cable for ten minutes or so.

    if that does not
    fix the problem, it means that there is an hardware fault, maybe the RAM or the motherboard.

    If you have worked on computer hardware before you may try removing one of the two ram moduiles, and test the other modules one at a time. If you have only one module, get a replacement and test it.
    Try also to start the motherboard without PCI cards (either than video adapter), and with hard disk and DVD unplugged, if it starts, then is one of the drives or PCI devices.

    If you do not have experience in working with electronics may be better calling a technician.

    Hi there: "I took the battery off the mother board for ten minutes and tested both rams separately and the comp did not boot."

    That probably means that the motherboard is gone.

    If you are in UK the whole Job will be around £100/£120. If you ask PC world to do the job, for example, they will charge you £65 labour + £ 50 or so for the motherboard, including VAT.

    If you are in US, there the parts are cheaper, and the whole repair should be approx. $120/$140 ($80 labor).

    The computer is still worth repair if you want to save some money. Sure, if you planned to get a new computer, this is the right moment.

What's your question? my proline laptop is not showing up the screen but it does show that its charging but doesn't show up the screen

That could be many problems. what your telling me is that u see the charge light when u charge it but when you turn it on nothing happens? this could be a number of things. I would hook up a monitor and see if anything shows up on the monitor if the laptop boots. if something does show up then its your laptop display cables that are bad.
Try This
--> First turn your computer off by pressing and holding down the start button. Next unplug the computer and then remove the battery. Press and hold down the start button for about 60 seconds. Release the button and plug in the computer. Press the start button and the display should return. Replace the battery. If this does not work, try it again up to four times. No results usually indicates a bad mother board. Hope this helps.

Acer x3400 wont start up

Remove the Power Cord and then press and hold the power button for 30 seconds. After 30 seconds plug the power cord back in and press the power button. If it reboots you had a Static Charge Buildup and released it by holding the power button for 30 seconds.

When you press the power button do you hear the fan running, disk drives running, cd drive clicks once, anything on the lcd screen? If not I would think your Power Supply is bad and needs to be replaced.

It's either the Power Supply or Motherboard.
