Pull cmos cell from motherbord for 10 minutes.
So all motherbord settings defaults.
Then reconnect ATX power supply connector from smps to motherbord.
If still face same issue then you need to change or repair your SMPS.it is in back top side of cpu cabinet.
Try with other smps if still same issue then your motherbord has some issue.
You can trouble shoot this issue with above step follow 1 by 1 .
Let me know if you need more assistanse.
Normally this would indicate a problem with one of 5 main things. Ram, CPU, Video card, power supply or System board. One thing I would try is to reset the bios. Unplug the power cord from the computer and hit the power button. This will release any unspent power from the power supply. Pull the jumper off of the system board by the battery and switch it to the other jumpers and then back to the original settings so that you start out as if the board was fresh from the box. If you dont see the jumper for doing this you can also remove the battery and then put it back in to reset the bios. If that doesnt do it, try the ram. I dont know the specs on this board so if you are using a plug in video card try another one. There is ram on the card and it or the GPU can be bad. Finally (besides the system board or CPU) make sure that you have a power supply that will run everything correctly.
Hope this helps you narrow it down.
Explain what you mean when you say 'when i open the pc from main switch'. Also, something you should try is updating the CMOS, or in other words flashing the BIOS firmware. Go to your motherboards manufacturers website and see if there are any BIOS updates for it.
Hi, to access the Bios Configuration Setup, On Any PC.
Depending On The Bios Manufacturer i.e Pheonix-AMI et,c.
You press F2 Or Delete Or Esc At The Initial System Boot-Up.
Power On. Press One of the designated Buttons immediately, after starting the computer.this should access the Computers Advanced Bios Settings.
** Please note:- Altering any settings in the bios, can cause undesireable effects to your computer**
Even failure To Start, Or Boot-Up.
From my own personnal experience, it is better to underclock a cpu rather than overclock it.
If a CPU Is designed To Run At a certain speed, running it above it,s designated speed cycle, can damage either the CPU Itself, the Memory Or Motherboard.
Probably wiser, to upgrade The CPU rather Than Overclock It.
