Kung hindi na kaya magstart up sa safemode or system restore, and there no important files needed to be retrieved, better to reformat at reinstall applications.
Pero if need muna kunin ang old files use Hiren's Boot. Para ma copy mo muna files to other media before formatting your harddrive.
It's a matter of preference, may sariling apps naman ang Apple devices. Pero kung paramihan ng compatible applications may marami sa Android. Kung movies, music and web browsing lang pag gamit mo sa phone wala naman magiging issue.
Kung driver lang try mo to baka makatulong. Driver Pack piliin mo yung offline kung gusto mo ng full copy, medyo malaki nga lang yung file. READ and update ONLY the drivers that needs to be updated. Hope this helps.
Kung nag-bo boot sa OS, and mouse or touch pad lang and di gumagana, download mo nalang yung driver. Check mo Device Manager if naka Windows ka, dun makikita ung mga devices na hindi properly installed ang drivers.
Remove and Clean RAM with eraser. Try mo iboot without RAM kapag may beep sound good sign yun ibog sabihin good yung board since nadedetect nya na walang memory. Turn off then ibalik ang RAM.
