Is it possible to repair a computer which doesn't boot?

Hi,



My part time interest is to fix computer software and hardware problem.



I had recently different experience with my friend's computer as it was not booting.



1. I double checked with hardware components if they were set correctly.

2. The reason processor fan turns on and then turns off.

3. I changed the SMPS unit to a brand new one so it might fix the problem but it did not work.

4. I took it to a regular computer servicing shop and they informed me that motherboard BIOS is not working.

5. I informed my friend the motherboard has to be changed.



After some days I got response saying that her uncle has fixed the computer and there was issue only with power supply.



I am confused. Is that possible or is my friend saying lies?







What are you opinion about this case?



Thank you in advance,

I am not there so I do not know if your friend is saying lies. Sometimes a BIOS reset MIGHT correct issues. The computer might not work no matter what you replace until the CMOS battery is removed or a jumper/hard reset is performed.
