Occasional restart during boot
About six or seven months ago I purchased a GB chip for my comp. I think it might be faulty, but I am unsure.
Sometimes when I restart my comp or am starting it up XP will begin to load, and then the computer turns off and begins to restart. Occasionally the XP loading logo becomes frozen, and I then have to do a hard reset.
Also, when I've been using my comp heavily and go to restart, it almost always happens.
Please tell me if you think I need new ram, or if you have any other suggestions.
