Bought one for my son. Never used, he came home from college plugged it in and it restarts every 5 minutes. Was within the warranty. Contacted customer support. They have you take apart the computer and PAY FOR SHIPPING TO THEM. The computer is HEAVY and very expensive to ship from Ohio to California. They shipped back the part and it still did not work. Wanted me to SHIP IT AGAIN and cover the cost of shipping. WHAT A WASTE OF A 1,000. Contacted Best Buy they will not help. Look at their BBB reviews which are horrible, even though they give them an A+ rating. I cannot understand why. This company is a FRAUD! Do not buy unless you get a solid warranty from the company you buy it from because Cyberpower PC will give you NOTHING BUT A HEADACHE.
