UR 22 problem?

Hello, I’ve been having some issues with my new laptop and am wondering whether it is anything to do with my UR22.

The main problem at the moment is when recording with my SM57. The recording either has a lot of hiss or noise and the waveform ranges from being slightly noisy to being a big rectangle with spikes coming off it and just white noise. This has happened even when there has been nothing plugged into the inputs and I’ve done a recording. Recording guitar plugged in is strangely ok.

Thanks

Maybe try another input (1 or 2), check +48V Phantom Power, CC-mode or another XLR cable just to troubleshoot and eliminate options.
