PC not booting

As far I guess your PC has has no signal to Monitor problem. First, you try few tricks which may be useful. open CPU case. take out all the hardware i.e hard disk, CPU Cooling Fan, RAM and any PCI card if fitted. clean mother board with any vaccum cleaner with hot air blow then reset every thing it may work if not

Second

then problem may be with mother board. go to any mother board reparing vendor may available in your city. there may be problem with BIOS chip. get it repaired it will cost only 300 - 400 RS. tell me your city name I will send You mother board reparing shop address. BYE good luck

Pull it out and reset it. Then try booting again. You may like to try cleaning the contacts with a Soft Rubber/Eraser before replacing it in the Socket.

If it has On Board Video replace the Power Supply with a Known Good One and see if it boots now.

Col

Change your power supply for a new one.

Please post back if you have any more problems or questions.

1. The beep may have been disabled in the BIOS/CYMOS settings so it may not give the beep sound.
2. The RAM may not be properly inserted in its slot as due to frequent use it may be loose so remove the RAM clean it properly (the circuit part - back and forth) with a clean paper (DO NOT TRY IT OFTEN) and insert it properly.
3. Check the VGA cable and the monitor.
4. Check your AGP/ graphics card on the board.
5. finally if nothing works then see a vendor as the problem my be with the mother-board.

I hope I may be of some help

All the Best.
