Win 7 Professional 64 bit freezes randomly - no BSODS
Hi
Around month ago I reinstalled my windows. Instalation went smooth, I instaled drivers and all necessary stuff.
After some time my PC just freezed, I was unable to do anything and all I could do was turning it off with power button as it is does not respond. Freezes were occuring at least once a day in random moments. While I was browsing internet or while I was playing games, last time while I was listening to music.
At first I installed fix from this link: Fix a Windows 7 System That Randomly Freezes | PCWorld and it help a bit. A bit because now freezes happen like once a week. Latest occured around one hour ago.
Not cool thing is it does not generate minidump file in my windows folder.
Also there is nothing in Event viewer.
Only errors says that previous system shutdown at 18:49:35 on 2017-02-22 was unexpected but there is no error log from this exact time.
Next fatal error is from Kernel-Power: System has rebooted without clean shutting down first.
Before reinstalation of win7 everything worked for around a year without any problems. I used the same drivers provided with hardware. I only instaled a bit newer GPU drivers.
Any suggestions how to fix that ?
