The machine comes loaded with Windows Vista, about 6 months ago I bought an SSD drive and upgraded to Windows 7 using a legitimate copy of Window 7 Professional.

All was fine, worked beautifully until after a while it started randomly shutting down. Not like "shutting down" I mean just plain 1 second on, next second off, as if someone had pulled the power. This seemed to get more frequent.

I reinstalled Win 7, again all was fine then it started again, after a couple more reinstalls (I am persistant) and the same ting happening after a few weeks eachtime, I thought it must be Win 7 on this hardare and gave up, reinstalling Win Vista, which never does it.

But then 2 of my friends got tthis laptop, and both on Win 7, neither with this issue..

So I thought it must be the SSD drive, so sent it back and got a new one.

Did it all over again, all was fine for 3 weeks then it started just shutting down again.. no warning, just off.

I disabled the auto shutdown in the advanced settings, but I don't get a dump file..

I made sure the ps isn't stopping the hard drives, in fact I have tried absolutely everything I can think off with no success...

I really need ideas and help, or its back to Vista for me

So over to you..

I dont have the Turbo Gear Software running..

I didnt bother to get the Asus Win 7 Free Upgrade offer, as I didnt want to upgrade from Vista, so I insatlled a Professional version which is running on many machines at my place of work with no issues. I dont have any of the Asus software on it, just vanilla windows with normal stuff, a few games, itunes etc etc

Both my freinds are running similar copies, both professional, one legitimate one not.

With that said it does feel like a driver issue, it certainly isn't heat as I have run checks of temps etc and it does this shut off thing irrelevant of temp.

But when it shuts down there is no BSOD, and no dump file as far as I can tell..

The most frustrating thing is on Vista its rock solid, never an issue.

Any SATA-IDE or SATA-AHCI controllers to check in the device manager/bios settings?

PS: Welcome to Sevenforums!

Hi and tahnkyou :)

What do you mean? check?

Heres my Device Manager in teh attachments.

Anyone else have any ideas for me to try?

Hi KIAEddZ,

You're in good hands here - we'll get to the bottom of this sooner or later.

Now, my initial thoughts were that your PSU was shot. How long have you had this computer for? And was it fine before you bought the new SSD?

Thanks,
Harvey Meale

Hey Harvey :)

Well I have had it about a year, but on Vista its rock solid and never crashes and on Win 7 it does the shut off thing, so I was reluctant to think it was the PSU (which is a 1000W PSU)

I havent yet tried Vista on the SSD drive to see if its a compatability issue between the SSD and Win 7, but its a very popular SSD drive (Samsung) so again am reluctant to think its this.

Have you checked the temps on your computer? Or CPU spikes? Does the machine shut down while running a particular app?
