Thanks. So I wasn't exactly sure which 5v line or if it mattered but I checked the line on I2C pins in the upper right of the ramps diagram and they were at 4.96v. Does that likely mean just stepper drivers or could the ramps board have problems? Is there any way of knowing which stepper drivers are bad or should I get all four new ones? ThanksQuote

If you somehow shorted a 12V line to the 5V line, you may have fried the logic side of the stepper drivers.
First thing to check: With no stepper drivers, what is the +5V line measuring (in Volts)? It should be pretty close to 5V. If so, then it's more likely the Arduino and LCD are OK, and just the stepper drivers are at fault.
