Thx for the quick reply.
I just checked on BIOS, its not changing the boot device order, and its right. I did clear the cmos and reset the bios, changed memory slots to force memory retraining.
And now the pc is cycling on and off 4 times before POSTing in safe mode. After that, if i press F1, go to the bios and manually choose the boot driver, it boots fine with no problem.
