My PC was working just fine the other day, when I went to go boot it on today the red flashing lights come on. When powered up the fans turn on and also my keyboard and mouse light up.

the CPU red light comes on and goes off
then the DRAM light comes on and goes off
then the CPU light comes back on and goes off
then VGA light comes on and goes off
then the boot light comes on and stays lit for a second or two and turns off

any help would greatly be appreciated.

Try to clear the cmos buy unplug the power to psu, take off the battery on the motherboard, press the power button for 10 secs, reseat the ram to slot 2 and 4 (incase you didnt put it on that slot).

If it have a dual bios, Press Power and reset for like 10 secs (it will repeadtly on and off while you're holding both for 10 secs) and it will mostly power off after the process, after that, power on and the backup bios will kick in and fix the main bios, i have a Gigabyte B75M HD3 with dual bios and this is how to trigger the backup bios to fix the main bios.

also before doing that try to replug all the connectors you have on the motherboard.
