Laptop freezes a lot

Hey, Ive been downloading some more drivers on the asus website, I believe it was the Intel storage manager or something. I rebooted and I've been going without a single freeze for a couple of hours now, so I believe it's fixed! Thanks a lot for your help mate!

Good stuff mate keep us posted just in case.

By the by if you want some more out of the machine try this it speeds things up a bit only you do lose some of the "bling" like transparency if you chose not to have it.
Optimize Windows 7

Thanks for the link, i'll look into it!

Okay, so when I checked "Turn off windows write-cache buffer flushing on the device" in the hard drive properties, it started freezing again. Now, I was using the laptop for about 6 hours without any freeze. Then I installed some directx drivers, checked "Turn off windows write-cache buffer flushing on the device" and set my power management to high performance instead of power saver which it was on. The freezes are way less frequent though and they only seem to occur when im playing some game.
The error in the system event log is now an "iaStor" error with ID 9. The description: "The device, \Device\Ide\iaStor0, did not respond within the timeout period."
Hope you can help :)

Ok Jasper that iaStor is an Intel item / driver and from this it seems like the problem.

But when you say you did a clean install what media did you use? I have seen other threads that quote changing the BIOS to ACHI for the SATA so do you know what yours is set for?

No keep it at that Jasper am going to have to look see again and post back if I cannot find anything I will get some help.

I admit, I have not read the whole thread, but might I suggest to hold down the Windows key (the one with the flag) and press R. in the dialogue box type services.msc, and press OK. Scroll down to Intel Rapid Storage Technology, highlight it and right click and select properties. In the drop down box set it to Automatic (delayed) and press OK.

I also noticed you went without a freeze until you '"Turn off windows write-cache buffer flushing on the device"'. Why not turn it back on and see if that helps your freezing problem.

Intel Rapid storage is Intel's Raid application, but it is the only way I know of to get IaStor which is Intel's AHCI driver. Once installed, you don't really need it, only the AHCI driver, otherwise you will be using, MSAHCI, Microsoft's AHCI driver. MASHCI is not bad to use, but you usually get a little better performance using Intel's. Having IRST does not mean you have to use raid and does very little that I know of unless you do. I install it to get iastor. If you installed IRST, there are 2 ways to find it. The easiest is go to control panel (catagory view) uninstall a program and it should be listed there. The other way is Device manager, expand IDE ATA/ATAPI controllers. At the bottom you will either see your chipset AHCI drivers listed or MSAHCI listed. There may be a lot of other stuff listed but that is what you are looking for. This is what mine looks like. The Intel 7 serise/C216 ahci controller is the ahci controller, otherwise it would be MSAHCI if you are in AHCI mode.


In control panel, uninstall programs this is what you would see if it is installed.



But, you should not be having freezes whether it is installed or not.
