The Lenovo PC I'm using in school, upon starting up and being used, randomly went into sleep mode. Upon doing so, the hardware started making whirring noises as well as beeps. Is there anyway I can fix this?
Computer makes odd noises?

The beeps are an error code. Like Morse code, the sequence is designed to say something like "there's a problem with the power supply." If you look up the manual for that model, you should be able to determine.
Things that whir in a PC are:
Power supply
CPU Fan
CD/DVD Drive
Case fans.
