My pc has been crashing few minutes after normal bootup. It works fine if I bootup in safe mode. I tried using blue screen view tool and tried updating a Realtek driver. But now I am getting another error related to atapi.sys driver. My pc specs are as follows: Windows Vista SP2 4 GB Ram 6 years old I used Norton 360, but after the crashes, Norton doesn't start nor am I able to uninstall it. Also, I am unable to restore to a prior restore point. Attached is a zip file containing the dump files. I am clueless. Any help is appreciated.
