Good afternoon folks I hope you can help. I have windows 10 installed was okay till about 4 weeks back, stated to get the BSOD. Firstly it was only happening once every 3 days or so. Ran my antispy/malware software to look for problems never found any problems.(Avast, superantispyware, Spybot and Malwarebytes) The BSOD errors are :- Bad pool header System pte misuse Security check failure Page fault in none page area Kernel security check failure Irql not less or equal. System security exception In event viewer, it has ID41 63 System has rebooted without cleanly shutting down. Then just 3 days back I got an error atihdwt6.sys. This is when the sh** hit the fan. It would just load up and crash with this error. I decided to format my hdd with dban and install windows 7. Done this and was okay for the day, decided to install windows 10 and have had 3 BSOD in the last 2 hours or so. I hope this makes sense to you all and you can help me fix this, if you need any more info please ask.
