I desperately need help….
I'm not really a computer expert or anything, I was just trying to help.
My boss's computer needed a new power supply 'cause the fan had become very noisy. It was also switching off and re-booting intermittently (It doesn't have a virus). So I took it home to put a new one in for him. I put a new power supply in and now it won't even boot anymore. I tried putting the old one back in, same problem. I reset the bios and it booted once, but I turned it off and back on again and it won't boot again.
I have to give it back to him tomorrow, any ideas would be greatly appreciated.
Thank you
