Windows 7 FREEZE & stops responding after 5-6 minutes of startup. sometime it takes very long time to startup and shows black screen. The mouse pointer works but the system freezes and after few seconds "Microsoft windows is not responding..."

Actually, I install windows 7 because the same thing was happening with windows 8 and 10. When I install windows 7 then it was normal till 5-6 days. But after it lags after start up and stop responding. I have to turn it off by holding power button and after restart the same thing happen. In Safe mode also same thing is happening. I have installed windows 7 3-4 times but crashes after 5-6 days. I haven't installed any drivers or any other programs except chrome. I have scan my system but no virus is shown. I think the problem is hardware related. Any suggestions please!!
