Circuit diagram for the V330 board at what looks like revision 7.0, supplied as a decrypted PDF of about 979 KB. The V330 code matches the style of MSI graphics card board numbers, so it should cover a video card power stage, GPU and memory section. A technician can trace a shorted rail back to its controller, check PWM enable signals and fan and display output circuits. Read the revision printed near the PCIe edge or on the back of the card and compare it before relying on values.
