The thread Windows 7 clock is running very fast contains several suggestions:
A. Switch the computer and all devices off at the wall and wait a few seconds, turn it back on, wait a few more seconds before pressing the power button.
B. Disabling in the BIOS the SVD (Secure virtualization mode on processors)
C. Update the BIOS and chipset driver (careful!)
D. Hardware problem with memory
E. To Register dll file and reset SNTP execute the following:
net stop w32time
w32tm /config /manualpeerlist:time.windows.com,0x4 /syncfromflags:MANUAL
net start w32time
