Recently my computer randomly restarted, and it's happened about 5 times in a couple weeks period. It's never done this before, and I formatted about 2 months ago so it's fairly new. When it restarts, I check the Event Viewer and I get the same Event ID 1003 message: I zipped the 5 minidump files that are in the Minidump folder, so hopefully there are enough to tell what's going on. I also noticed (by having task manager open) that everytime I open a folder/firefox/etc.. the CPU Usage jumps to around 40-50%, then back down. The PF Usage is always steady. Any help is appreciated.
