Hello all This is my first post in here. Please bear over with my English – it is not my native language. My problem is on a Media Centre machine where I recently upgraded Motherboard and processor. I have the following setup on the machine: MB: Asus P8H77-MLE CPU: Intel i3 2120 2x2 GB Kingston ram OCZ Agility 3 SSD 120 GB 1,5 TB WD Caviar Green Asus P7131 Tuner TERRATEC Cinergy DT USB XS Diversity Hauppauge! WinTV-NOVA-T-Stick-Diversity Hauppauge! Smart CI USB My previous setup was with a AMD 240e. I use Microsoft Security Essentials for antivirus and have firewall turned on. The Media Centre machine is on for 24/7 on sleep mode for recordings or turned on for showing recordings. Since the upgrade I have BSOD most times after it is turned on after sleep. The STOP occurs 4-5 minutes after the wake up either the wakeup is initiated from a recording or from user. I even see BSOD occur in the middle of the night where I have no recordings or other activity. I have made several new install and tried to exclude the SSD and install a 32 bit Win7 – but the BSOD still occurs 4-5 min after awake.
