Frequent Windows 7 freezes on new Lenovo G570
Hi all,
My first time posting to a forum like this, usually I just read existing responses but this time my skills have failed me. I got a new Lenovo G570 which has been frequently freezing up, requiring a restart. Frequency varies from every 20 minutes to a few hours, in a wide variety of states and activities, sometimes even while installing updates at shutdown. Computer use seems to make it slightly worse. It can sit for 8 hours or more without problem if nothing is done right after boot, or if firefox is just up and sitting there. With Windows Media Player going, it lasts about 4 or 5 hours maybe. This is with me not interacting with it at all. When I do, it lasts much longer if I use the touchpad and leave the USB mouse unconnected.
I'm using Win 7 Home Premium 64 bit, OEM from Lenovo. I reinstalled it once using the system recovery utility from Lenovo, OneKey Recovery.
Performance is good right up until the point of the freeze, when everything immediately halts. Sounds will become a (near?) constant tone. The computer does not automatically restart or show any error screen.
My great appreciation for any help with this.
ETA: I also ran it in safe mode for a day, simultaneously using WMP, Open Office, and USB mouse, and there were no problems.
