Almost every other time I start my pc I can use it just fine but when I get to desktop on windows 8 or use any browser for the internet my display driver crashes. I can't do anything on my computer but wave my mouse around, waiting for it to recover isn't an option as I have waited for it and even left it running for an hour and came back to it still frozen but my mouse working. What could be the cause? Would formatting and reinstalling windows fix it? (I was planning on doing this anyways) If so I will most definitely do it. Any ideas otherwise though on how to fix it or how I can troubleshoot this better to find the cause?
