I have 2 DELL PCs OPTIPLEX 270 and had problems with the motherboards.
It was fine the last time i used it, but suddenly, when i checked, the motherboard alco were burnt (small burnt bubble), what could be the cause? Should i have the motherboard fix or should i buy new PC?
1 of them only showed up until the windows logo and it turned black / hang. So i have to keep restarting it again and again. But once it went through to desktop, it was fine.
but the other PC, it went through to the desktop fast, but when i tried to open files after files, it hanged and have to restart again.
What could cause this problem? I need help pls.
