Start over.
Return to the character when you have the proper motivation. You describe playing the character as if it were a chore, with that mentality no matter what you do, you'll grow bored.
There is a reason transferring characters across platforms and mediums rarely ends well, which it sounds like you've done, different status quo.
Once you've done that, you need to shift your attitude, that seems to be what alienates you from a majority of the factions you've described yourself as being blacklisted from. No one owes you roleplay, nor the benefit of the doubt when it comes to character interactions.
Can speak from my own experience disbaling the typical laptop bloatware (McAfee, Norton, Etc) helped a lot, as it occupied lots of RAM and also prevented Rage from working properly. Atop that, as mentioned above cooler temperatures helped a lot as well, using compressed air to blow out my fans and heatsinks have led me to once again have a smooth experience.
