Summary: My husband built me a computer with this motherboard late last year and it has been the best computer I have ever owned. I do a lot of Internet surfing and I have never had a crash. I have this system on 24/7 and it has never run hot and always starts and shuts down properly. I have been able to mulitask without skipping a beat. I am running Windows XP Professional and a lot of software on this system and everything works fantastic.
