Can you recommend a simple todo check list if a PC suddenly don't switch on. I'm done checking the external parts such as cable, supply and AVR. I'm checking now the CPU and its internal parts. Which should I check first and in what order? I'm familiar with the terminologies and ID'ing parts. By the way the PCU is an early models of P4 class. Thanks in advance.

Hai, Is it totally doesn't switch on?? Any power led is shown in your motherboard. First think you have to check is the SMPS. If it is fine then go for the next part. Check each pin whether the power is proper in the outs of SMPS. You could use a multimeter for that. I have faced an issue with my desktop, one month before. When we switch on, it starts and on for at-least 5 seconds(fan starts rotating). Then suddenly it stops. Is that the case for you? If so you have to check with some motherboard expert. If not check whether the power is coming properly to motherboard. Also remove the extra peripherals and try to start your system. Any damage in those also can make problems. Also remove RAM, Drives, Floppy drives, HDD etc and then try to power on. Check it and let me know the result. Regards, Reyas

Thanks for your presence here. One of the my cousins desktop used to reboot continuously itself and take many restarts to get started and some time it will restart automatically while working. If the poser cable is connected to it, unexpectedly it will start working itself even after shout down, even no one in the home. All these are not regular one and this will happen very often and we can not say this is happening always. If we call some technician to show its performance, we are not able to show it to him as it used to work properly during that time.Even we formatted the system to remove virus if any. Still soon after the formatting , it is repeating.What could be the reason for that?

Hi, First of all thanks for your comment. I have faced almost the same situation two months before. That is when I switch on my laptop, it will switch off or restarts automatically. If the power cable is connected then the probability is more. I figure out from my issue that the CPU fan will not start with my Laptop power on process. This can occur because of two reasons. 1: The CPU fan have lot of dust and unable to rotate. 2: The thermistor which is detecting the CPU heating is not working or covered with any dust particles. For me it is working fine after cleaning my laptop. In my case after a few restart, the CPU fan will start and with some small noise. So please find out whether the fan is working properly or not. Also check whether the heat produced using any available tool. If you are not able to fix it, check the motherboard and SMPS with any technicians. Regards, Reyas..

Thanks for your suggestions.Mine is desktop and hence the possibilities are more for the desktop to have dusts.The fans are making much noise after a run of half an hour. We changed the SMPS very recently as if the problem is with the SMPS. But still the problem continues. But we did not clean the fans well and let us do this first. AS the desktop is more than 5 years old, there may be problems with the mother board also. But, changing the mother board may cost more. First let us try to clean the dust in the CPU and I will keep you informed about the progress.Thanks again for spending your valuable time to resolve my problem.
