Recently i cleaned the pc and uplugged all power connections. now the pc is taking long time to get to boot screen than usual,booting is normal,sometimes display doesn't show after the cmos beep sound also it takes long time to hear that beep sound.Also for some time before boot screen it says new hardware found every time and resetting the time.What may be the issue
