I had this issue A while back, here's what you can try
# Install chipset drivers for your motherboard
# roll back your drivers from device manager
# try installing your graphics card drivers without GeForce experience
# disable any suspend or power management for usb
# update windows
If those don't work its probably a tracking issue
# do your base stations have a clear view of your headset?
# do your base stations have a green light on both?
# do you get any error codes in steam vr?
# are your base stations on the right channels? (b and c)
# when was the last time it worked?
