In my office there is a celeron 1.7Ghz system.The problem is that when I turn on the system only the motherboard LED starts glowing. The SMPS does not turn on .But the SMPS worked when I disconnected it from the motherboard.So I wanted to know whether it is a motherboard problem.If so, is it a major problem
or a minor problem.

If the power supply does not turn on when you hit the switch but the motherboard led lights do then I am going to say that the power supply is bad.... I don't know how you got it to work when you removed it from the motherboard as it requires a connection to turn on at all. Plugging in the power cord for the power supply by itself will not turn the power supply on. It needs the feed back from a switch to turn everything on.....

Start\run\msconfig\startup,check only you REALLY NEED

What does that have to do with a possible failing power supply or motherboard issue. That is only for troubleshooting windows issues!

You may try to reconnect the systems wiring from the main connection between the power supply and your motherboard. Then also reconnect the cabling between the hard drives and the power works, after doing so, attempt turning the computer on. If the computer still doesn’t turn on, seek for a power supply that provides higher wattage. This is usually suggested for computer with extra gears, like tv out, additional drives with higher capacities.

For this kind of problems, it is also possible that your hard disk has a bit of a problem. For hard disk problems, there are several solutions: like repairing the Operating System, by inserting the OS disk into the compact disk drive, then choosing Repair and following the instructions that best suits the situation of your computer. Aside from the repair, reformatting the hard disk would also be a solution, although this option is the least liked by users since it usually erases all the files located in your computer unless back ups have been made. Making back up for files is possible by using the same compact disk used for reformatting or reformatting. If the files are no longer important or needed by the user, reformatting the computer could possibly solve the problem.
