My computer encounters BSOD and it will restart with errors such as IRQL_NOT_LESS_OR_EQUAL or BAD_POOL_CALLER or PAGE_FAULT_IN_NONPAGED_AREA. The occurrence of the BSOD is intermittent. It will run fine for a few days or sometimes up to a week and then I would encounter a few or sometimes several BSOD in a row and after that it will run fine for a few days or a week until the BSOD starts occurring again. This cycle keeps on repeat itself. Please help.
