Hey guys, i've been going through a lot of the posts and can't seem to find one that exactly fits my problem. So I recently changed cases and I installed the motherboard and other computer devices into a new case and forgot to install the base screws. As a result, the motherboard was touching the surface of the case. After installation, the computer work perfectly for two days, when one day it froze and has since then refused to boot. Upon pressing the power switch, the cpu fan and the case fan turn on, but the power supply fan does not. In addition, there is not a beep sound when the system is powered up. I have removed all components and have tried to run the system with just the motherboard, the cpu and one memory stick, but it still refuses to boot. Is this a motherboard issue? If so, i've been thinking about upgrading, nothing too fancy, but what are my upgrade options? Or is this a power supply issue since the power supply fan refuses to start even though the cpu and case fans do? I've also tried removing the cmos battery and putting it back in and that doesnt work. Hope to hear from someone soon. Thank you.
