Happy New Year!
First of all. I'm not an expert and my english sucks, but I will try yo help you.
Today I turn on my computer and I ran the turbo boost gadget and it showed me an error. It asked me to reboot my computer or to reinstall the turbo gadget. So I reboot my computer and still didn't work, so I decided to reinstall the turbo gadget and now it's working perfectly
So, before you reinstall again all your OS, enter in the BIOS and look if the Turbo boost it's on or off.
To enter in the BIOS you just press (I guess) the key "supr" or the "clear" key.Then search in all the options until you find it.
I don't remember exactly the pad to get there, but I'm sure you can easy find it in google.
I hope this helps you.
I am litterally having the same problem... i have just bought an Asus G73 laptop and when i first bought t i would play high performance games on ultra graphics settings at over 200 fps. Recently my intel boost has been staying at 1.6 ghz constantly and not fluctuating like it should. My fps has decreasted to 30 sometimes and never goes above 100 now... i have ****** with my startup's but i turned them all back on and it still doesnt work. its there a way to overclock it so it runs at 2.93 ghz contantly? Please help, losing rating due to lag! thank you! <3
