Reboot failure

[yrana2002]

Hello, recently my comp has started not to reboot (really). On issuing the reboot command, it terminates all the applications & comes to windows is shuuting down, & then the screen goes blank.... with the CPU light still on & nothing happens until i have to turn off the power supply. I made two changes to my system before this happened:..
1. REplacing tcpip.sys to change max. tcp settings
2. Setting activate time for auto start in BIOS settings.
Are these responsible for the change?

1. REplacing tcpip.sys to change max. tcp settings

for this u may use this command, Start > RUN > sfc /scannow

& for rebooting issue... cant give u exact idea... but u may take a look at this...
