I was trying to OC my Celeron D 2.4GHz. i was going slow since it was like my first time OC'ing and i had no idea what i was i doing. so i get it up to 2.60GHz, but it keeps crashing right after i sign into my account, sometimes before. is this because my CPU isn't getting enough voltage or what? i have an ASUS P4R800-V Deluxe if that helps.
