Daemon tools uses sptd.sys and it's own emulation layer.

If it's DRIVER_IRQL_NOT_LESS_OR_EQUAL this usually does indicate Hardware or Driver problems.

My first guess when I see this is "Time to buy some new RAM... better find memtest disk", so you may wish to run memtest86 if you have it available.

Other than that, go into device manager, View -> Show Hidden Devices, and have a look around there for anything suspicious. Do be wary that there are a lot of dodgy-named drivers under the non-plug and play drivers bit.
