Hi:
Unless the turntable or arm is damaged, it is the cartridge. If you are using Rega's stock felt mat on the platter and a Rega cartridge, the VTA is pre-set and perfect -- you can't adjust VTA anyway with the stock RB-300 arm.
Sounds like the cartridge is dead. Twl is correct -- DO NOT play records or you could damage them. If you replace the cartridge with another Rega cartridge, buy a "Super Bias" or better.
Good luck.
