Windows 7: win7 x64 reboots after power off for one night

win7 x64 reboots after power off for one night

I have a most peculiar problem. I have my computer on a power connector bloc with a switch. I disconnect power for the computer and the rest every evening. The following morning I connect power again and start my PC. It always reboots after selecting win7 in the boot menu. Restarting in save mode and then in normal mode usually solves the problem but sometimes it won't start in save mode also. Disconnecting the power again and waiting 15 seconds helps. After that I manage to get win7 working. It stays working fine.
These problems never occured with winXP on the same machine.
I changed my power supply yesterday, because the log gave a Kernel-power error 41. This is not the solution.
Can anybody help?

Problem is solved

I don't exactly know what solved the problem but it is solved. I can be because I overclocked the processor so it has the same bus frequency as the memory or it was a the USB harddisk or my card reader. I swapped there USB connection. The main thing is it works again.
