for a few weeks i been noticing that if i make any changes to bios and restart the computer it just hangs. There is nothing on the screen even if i let it run for 30 minutes. I have to manually take out the power cable and wait a few seconds before plugging it back in. Then it boots up fine.

What ever changes you're doing to bios is rendering your system unstable... I'd suggest clearing cmos and starting from scratch... If the system has some overclocking done in anyway, you might wanna rethink that or reduce it....
