Asus K55N Laptop Freezing

Hello cameroncr95. Welcome to the forum.

We can help, but it will cost you $5.00.

Ha Ha, just kidding.

First, how long ago did you install W7?
Does it freeze randomly, after a certain amount of time, or when you do something?

2 things you should do/try to start:

• Go into your BIOS settings, and look through the tabs to see if you can find settings for "Secure Boot" and "CSM". Let us know what the settings are.
• Start Windows in Safe Mode: Press the F8 key repeatedly when you first start the laptop and when the Windows Boot Menu comes up choose: "Start Safe Mode with Networking". Run it there for a while to see if the freezing stops.

Let's start there and see where it goes.

In general, you would disable Secure Boot (use "Other OS" setting).
But CSM you could leave at default value. If it is a pure UEFI system the module could be disabled, but a hybrid system might work better with it enabled.

These 2 settings usually only affect Windows installation. I'm not holding out hope that this is the cause of your problem, but it is easy to experiment with and has little chance of disruption.

I am more interested in what happens in Safe Mode. I am guessing it is a driver problem. Suspect #1.

Gotta run. I'll think about it.

Freezes are tough because unlike blue screens, they don't leave any log that you can use to track down the culprit.
Historically freezes are caused by a conflict between devices or drivers. They can also be power related. But since this laptop ran fine on Win8, then we can suspect it might be a driver.

Is this a fresh install of Windows 7? Within the last week or two?

Are you using all new Windows 7 drivers downloaded from the Asus website, or are you using the same drivers you got with the laptop for Win8?

If you got to Event Viewer (Start > search: Event Viewer) Do you see anything next to Critical listed?
You might also tell us what you see under Errors. Double click each entry and read what it says under the General Tab.

I assume that when Windows freezes you are recovering by holding down the power button till the system shuts down. This is OK, because there is not much else you can do, but that would explain the critical errors.

What we are interested in is the Critical and Error listings. You can isolate these by opening Event Viewer > then click the + sign next to Critical > then note what is listed below. You can ignore the Event 41, Kernal-Power errors as we know what causes those (you!).
Then click the + sign next to Error and note (or post) what you see there.

Maybe that will yield some clues.
