Have you tried testing the PSU? It might be faulty. Also, try running some memtests with one memory module at a time.

I thought to Replace PSU but when the system works normally from Linux CD i said the PSU is not a possible reason

Linux is more tolerant of hardware faults than Windows, especially PSU and memory faults. Linux working better than Windows is not really a good sign. For example, I had an old computer with faulty memory that would boot into my Tinycore live boot disk, but would not work with Windows until I replaced the memory. I later found out that the memory had a seemingly damaged chip on one of the modules.

If that doesn't work, then maybe there's something wrong with your hard drive.

The best place to look is really the PSU,

as windows is more picky than Linux as ^ blazorthon wrote already.
