Been having some problems with blue screens for a while now. I recently managed (I think) to deal with ones related to fwpkclnt.sys, thanks to some help on the web. But today I started having problems again. DRIVER IRQL NOT LESS THAN EQUAL and tcpip.sys were the two names I managed to catch during the BSODs. In addition, my Windows Installer has been giving me this: The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance. I've put the contents of my minidump folder in a zip. Thanks for the help in advance. EDIT: Additional details. I've run Malwarebytes, and it doesn't seem to be picking up any malicious stuff. I tried adding the "MEMORY.dmp" file in another zip, but it's too big. This batch of bluescreens started when I was trying to install Java, to use the program "Tokentool."
