Hi, recently i dont know what happened, but my computer stopped working and just didn't com eon. So, i thought it must have been the power supply, so i got a new power suplly, fitted it in and evrything only to find that the system didn't load up again!! Now, im worried that the motherboard is faulty as i built this pc only a year ago!! Is there anythign else that it could be? or am i doing the wrong thing? please helpppppp

I have just been through a similar problem. I had the power supply tested and it showed that it was working fine. I assumed that it was the motherboard. I decided to replace the board and the CPU. May as well upgrade while I am doing it, right? Still the same problem. I replaced the memory. still the same problem. I replaced the case still the same problem. Ended up being the power supply? How, you ask? Didn't you have it tested? Yes I did. The problem was in the plug that goes into the motherboard from the power supply. Whenever I moved the wires it would turn on and off. Your problem could be any one of those I mentioned. See if you can find someone with a similar system that will let you swap parts to find the problem. Is the computer completely dead? Not a beep or a fan turn? If that is the case it is probably the clip on the motherboard where the power supply plugs in. Or could be a bad CPU or Ram?

Always remember the bare minimum devices to boot a machine (not necessarily boot to anything, just being able to boot : KB, Power, and video. How many RAM chips are there? Take all out but one. boot it up. If you get any usable video at all go into bios and take a look around for something that may be keeping it from going further. When you replaced the power supply (ps), did it or the old one ever power up? Or was the m/b keeping the ps from powering up too? Does anything happen at all when you hit the power button? If it yells at you with the perfectly repetitive tone of beeeeep…beeeeep…beeeeep…beeeeep…and so on without changing = ram problem. Change chips to a diff one – still only one on board unless for some funky reason your board requires two to be present, but it shouldn’t. I haven’t seen that requirement for years. And YES, this means taking ALL cards out of the box and having only a bare bones motherboard with just power connected to it, a vid card and the keyboard. That’s it. And not some vid card that requires any special stuff to boot to either. Remember; stick with basic stuff here to troubleshoot. I always use to have a little pathetic PCI trident vid card on hand that only had about 4mb on it - but it was great to troubleshoot m/b’s though. Once you have video, hook up your floppy drive and boot to a dos disk. Next add a hd to boot to also. If that works, keep adding basic components to the mix, like your cdrom drive. Keep in mind you are shutting down and adding one component at a time! I know it is painstakingly slow of a process, but it is complete in proper troubleshooting to identify exactly what is failing and keeping it from booting. Start adding cards as you go along, assuming you have a continuously bootable machine every time you change the hardware. Post back with any further progress and questions you may have. I am sure I missed a few things, but this may have helped you get the idea of just how basic you need to break down anything (pretty much in your entire life for that matter; i.e., cars, computers, anything mechanical or electronic) to properly troubleshoot it.

Hi, in response to your great help, i get a little fan turn. But, Tyson, if u came across the power supply problem, how did you solve it? Thanks for the great help
