when I install windows 8.1 its freezing

i have the same problem, but i will tell u something that i have idea to handle that problem

first : install normally, but when 100% and laptop will restart, go to bios (f2) and boot > than change HDD to number 1, and USB or DVD number 2

second : save and change

then will restart, and that problem will resolve

or

when u reinstall, format ur primary drive windows, C if u using C become default windows drive.. and install

do the same thing like when install finish 100 % and will restart. when restart go to bios, change setting to (legacy), change HDD to number one.. save and exit

A clean install is where you completely wipe the hard drive and start from scratch.

System Restore basically restores a previous system state which should resolve any issues caused by software or system updates. To run a system restore in Windows 8.1 do the following:

• Use Windows-C to open the Charms bar on the desktop and select Settings > Control Panel from the

options.

• Select System and Security there, and then System again
• Select Advanced system settings on the right and switch to System Protection in the window that opens up
• Click on System Restore and select one of the available restore points to restore a previous system state.
• Note that the PC needs to be rebooted as part of the process.

For your data security, you'd better do system backup before doing reinstalling.
