My laptop is Toshiba Satellite L750-1N3.
I have a problem with laptop hdd.
Couple days ago i started to watch movie and got not responding VLC program. After restart waited 15 minutes to get system ready. All apps crashing or i need to wait around 15sec. to start.
I decided to install new OS. I waited around 3h for new OS. New OS was work same like a old one.
After that i delete and format partition, and create 2 new one. Also try with Win8. Before win8 i was use win7.
Same thing. Around 3h installation. All was slow and freeze any action. I tried to install OS from my desktop pc with laptop hdd. Same thing...
HDD was checked with windows check disk. All is fine. Without any bad sector.
Tnx in advance

All best
