System hangs once per day, no error message
Hi. I was wondering if anyone could assist me in figuring out a problem with a computer running Windows 7?
The OS hangs once per day. There is no error message, it just hangs after about 15 mins from starting the computer (and only once per day; after I reboot, the system no longer hangs). It also seems like it's a problem with windows explorer, because sometimes the task bar becomes unresponsive and I'm unable to use CTRL+ALT+DEL to bring up the task manager, but I can still switch to open application windows for a minute or two and they work normally, until the system hangs completely.
I've looked at everything that I could think of and searched online for help. Win 7 is updated. I've checked any weird applications or processes running. I've checked the task scheduler to see if anything strange was set to run on boot up/once per day. I downloaded every troubleshooter I could find on the Win 7 site, no problems were detected. I used disk clean up. I checked for any security problems. The only thing I didn't try was to restore the installation, because the computer had an OEM installation of Win Vista which I later upgraded to Win 7, so I only have the Win 7 update DVD, and I'm not sure that'll work or if I have to create some installation discs somewhere?
The curious thing is that I checked for recently updated software and basically uninstalled everything that I had updated the last few months (Java plugin, Microsoft .NET and Flash). This seemed to fix the problem and I had no need for any of those, so all good. But two weeks later, the problem returned. So I have no idea. Maybe I have some weird trojan on the computer and the person exploiting it went on vacation for two weeks in August?
Can you help or give me any pointers? Please let me know if you need me to post any information.
Thank you very much!
