Windows 7 BSOD

[Martin_03]

My problem is that I have a recurrent BSOD that reads "bad_pool_caller" but it only occurs when I have 2 or more users accounts open. Why could this be happenning?
This is what I get from bluescreenview:

In the case of bad_pool_caller, what has happened is that a thread in your processor has made a bad pool request. This means that it’s asking to use resources that are unavailable, nonexistent, or in use by another thread. It could also mean that the pool header is corrupted — regardless of the particular error, it, like most BSoDs, is caused by driver issues.

Ok. But why does this only happen when I have 2 user accounts open?

One account might be using resources the other is trying to access.

Running two user accounts at the same time is using the same resources so when the processor is trying to use one driver for both accounts at the same time so one account does not have what it needs then a crash happens
