3 Different BSOD'S today

First one is:

fltmgr.sys (system_service_exception)

bad_pool_header (which is something to do with malwarebytes I think but I took that out my system

and attempted write to read only memory

(I think I have dump files for all of them)

To update. I've had BSOD number 4 but this time no dump file (because I refreshed the installation) It's possibly something to do with snappy driver's or the intel chipset software causing it (I think)

BSOD Number 5 this time memory_management

Make that 6. This is a nightmare

OK A strange twist. I went into the BIOS last night (done memtest which came back clear) but went into the memtest and changed some settings (to do with the fan) and not had another yet (although could be pot luck) I'll keep monitoring but would be nice to know if something is going on
