Try to remove EVERYTHING that's not strictly necessary and try to install. Leave just one stick of RAM, onboard video if there is any, only one hard disk. If that fails reset the BIOS. There should be a jumper on the motherboard for that purpose that is named JBAT or CLEAR CMOS. If it is able to restart properly after that, then it was a BIOS glitch or motherboard fails to allocate resources properly. If it works, next time try putting the TV tuner card in a different PCI slot.

I dont have clear cmos, i only have cmos battery.... so i have to remove and wait for 15mins.

Are you using a wireless keyboard or mouse?

No

The problem was in graphics card. I removed it, now everything works fine. Also you have to clear cmos.
