The computer is custom build, no pre-installed windows.
I had windows 7 about a year ago, and had this problem then I went to windows 8, everything was fine but I decided to come back to win7 and the problem come back...
So I did a clean Windows 7 install, all up to date and then out of the blue a problem appeared.
Windows clock sometimes goes twice the speed (1 secound = 0.5 secounds in real time) and when it does and auto synchronize and reaches the time it was before for example (IRL it was 12:00 but the Windows clock says 12:10, so after synchronize it goes to normal 12:00, but when it goes to 12:10 my LAN turns off, when I do diagnose it displays that: ("Local Area Connection" doesn't have a valid IP configuration) and internet comes back).
The BIOS clock runs fine, the battery is fine (remember I just came from windows 8 that I used for 6 months and everything was fine. Also used windows before that and no such problem occurred)
I tried restarting the service and configure it, nothing helps...
I tried all the solutions I could find on the Internet like
net stop w32time
w32tm /unregister
w32tm /register
regsvr32 c:\windows\system32\w32time.dll
w32tm /config /manualpeerlist:time.windows.com,0x4 /syncfromflags:MANUAL
net start w32time
even did a sfc /scannow
and it found nothing wrong
Nothing helps... I cant do anything online because the time keeps going up and Internet crashes...
I don't want to spend another few hours to reinstall Windows and find out its still there...
The drivers are installed.
I am guessing its a software problem, but can't figure out what does it.
EDIT: The thing is I had windows 7 before and it worked fine until one day it just started to have this time problem.
/useptimer
switch and bcdedit command line usinguseplatformclock
. You might read up on these two options (I think win7 requires bcdedit). At the very least it is an easy switch to set and you'll know right away since your timer drifts so quickly.Windows clock sometimes goes twice the speed
So if you open the Windows clock, does the second-hand rotate at double-speed?
