today after starting my pc it goes again to bios, and it goes again and again.( 3rd day in a row)
then i updated my bios first, installed another window,

from three days im installing windows and after leaving my pc off for some hours , when id restart it then it goes to bios,

then i talked to the person where i purchased all parts, he told me there is a problem in my ssd ( corsair mp510 480 gb ), go to service centre.

to find if there is a problem in my ssd, i installed and use hd sentinels, but it shows my ssd and hdd is in good condition with no errors.
he also told me to install windows in harddisk and see if the problem comes again.

guys, help me to find the problem, its a new pc

Did you do any overclocks?
today is 4th day of my pc, started my pc in the morning, it worked normally,
maybe the problem was causing due to the old bios,
yesterday i updated it and today my pc is working normally.

thank you, folks for the suggestions.

now i have to wait for 2-3 days more to see if the prblem repeats or not.
