Hi

The first idea I would try is to disable all the sleep/power saving modes in the BIOS.

Sorry for late reply
I updated the bios to f14 from gigabyte site
I found that its a problem of PCI Express slot
I placed my GPU in 2nd PCI Express slot
PC is working fine for hours & hours after changing the slot of GPU
I will replace my mobo as it is in warranty
Thanx everyone for their help.
