often, when I want to put computer into sleep mode or sometimes when I restart it, procedure doesn't finish, display usually turns off, but computer is still running. The only option is to turn it off manually by holding power button.
After restarting I have a lot of (15) errors in system log:
A timeout (30000 milliseconds) was reached while waiting for a transaction response from the XXXXXX service.
XXXXXX = iphlpsvc, Schedule, SENS, BITS, CertPropSvc, EapHost ... etc.
Several days ago I have updated my bios and some drivers, so I suspect that the reason may be some driver.
I have dell latitude e4310 notebook running Win7x64 SP1.
If the problem is in driver, how can I find out which driver is problematic? Or do you have any other ideas?
Thanks in advance
