Marciton and wolfydog,

I was just thinking. Do you guys use any bootloaders or bios patches for Windows 7?

I am running my Windows 7 Ultimate 32bit RTM without any bootloaders or bios patches and everything works.

Just a thought.

Lexxion

lexxion please help!

during step 3

Second command you do is:

cacls c:\windows\system32\drivers\vgapnp.sys /G peter:F


i recieve the following error: invalid parameter "/g"

i am using icacls because cacls doesnt work

Did you substitute 'peter' with your username?

yes i did. still not working

If you use 'cacls' command what error do you get?

Did this work ok?

takeown /f c:\windows\system32\drivers\vgapnp.sys

Try pasting the 'cacls' command line from my tutorial and replace the username

It might be case sensitive (the /G )

takeown suceeds. using cacls returns "no mapping between account names and security ids was done."

Hmm... it looks like the 'cacls' command works ok but the message that you get is weird

Microsoft has something to say about it:

You receive a "No mapping between account names and security IDs was done" error when you edit and then save a Group Policy object in Windows XP Professional

What it means I am not really sure. You might want to scroll to the bottom of that page.

Also, does your account has admin rights? I would suggest logging in with the account that has admin rights or give the current account 'administrator' privileges and then trying again with 'cacls' command

when using Cacls i now receive error: invalid arguments. NOTE: cacls is now deprecated, please use Icalcs.

Hmm... Its hard for me to give you any solution because I did not experience any problems with using 'cacls' command with Windows 7 Ultimate 32 bit. I know 'icacls' should work the same way.

I would look on the net for the errors you are getting and try to figure out why you cannot use it.

Lexxion, thank you for your solution. It appears to have worked for me. I've got a Dell 700m that I purchased back in 2005 and I am glad that I can use Windows 7 on this machine (sans Aero).

However, I am having an issue, which may or may not be caused by the video driver. After using the laptop for anywhere between 30 minutes to an hour, the laptop will simply shut down for no apparent reason. This has happened both when my laptop was plugged in as well as when it was running on battery.

I'm not sure if there's an error log of some sort where I can determine what is causing my computer to randomly shut down. Does anyone know?

Just as an FYI, in addition to the video driver, the only other drivers that weren't automatically found by Windows 7 were by printer driver (a Samsung ML-1740) and a "mass storage controller," which was a Texas Instrument SD card reader. I was able to find the driver for the TI card reader.

I uninstalled and re-installed both the media card and video drivers, so we'll see if I continue having this problem.

However, if anyone can tell me how if there's a way to diagnose my issue so that I know what's causing the random shutdowns, I'd greatly appreciate it.

Again, thanks Lexxion for such a great workaround!

No problem JOL,

I would check your power options and make sure the laptop does not hibernate or sleep. I would put it on ALWAYS on and wait that amount of time to see if it shuts down. If problem persists try some kind of temperature monitoring utility to check temperature. I think when it gets too hot it might shut off by itself.

Just some suggestions.
