Hello, I have been having multiple blue screen problems lately over the last couple of weeks, have done system restore and other things as well same thing happening driver less than equal one and a other one called bad pool header. I have updated my drivers to my belief but still get it. I went online today downloaded a program called whocrashed and i looked into it and it said the bad pool header one was likely caused by malwarebytes? I also should not been using malwarebytes for years and have not had this issue before. also the other one though it did not catch was a driver less than equal blue screen this program did catch 2 blue screen problems been having of bad pool header. I have updated my computer of drives I believe my graphics card and so on. I also looked into the network adaptors under device manager and manually went to all of them and slected update drivers but it came back on all of them saying all up to date. Unless i am missing something?
