Windows 7 clean install Problem

Last response: in Windows 7

I'm not sure if this is hardware of software problem so I decided to put it down in here.

My computer is about 6 months old and i just clean installed W7 professional. It had xp before that

The problem is that now the pc will start up fine but after a few minutes (2 at most) it just turns itself off. It goes through the logging off then saving computer settings then shutting down as if i turned it off.

So far I've tried starting it up in safe mode and the same thing happens, it will do the same thing if its been off all night so I'm inclined to rule out over heating as the cause. The ambiant temperature is also about 20oC so its not hot at all on start up.

I've also tryed restoring the system to a previous date but the computer just turns itself off before it can be finished.

incase it helps here are a few more details:

No error reports

GIGABYTE GA-G41M-ES2L LGA 775 Intel G41 Micro ATX Intel Motherboard


GTX 260

550w Kingwin Psu

If there is any more information I can give you then please say!

Is this a genuine Microsoft Windows 7 disk? if so is it OEM or retail/upgrade?
There is nothing in what you have provided to give any clue to the problem other then a faulty instalation, or possibly the disk itself.
Did it work at all after the first install, or has it been like this from the start.

Genuine Microsoft Windows 7 Retail. Everything has worked fine except for this. I'm thinking its the power except for the fact that it does not instantly turn off but turn off as though i made it.

It still may be overheating.
Have you opened the case and made sure that your cpu fan is secured.

I had a bracket break on my cpu fan once and then it would shutdown after about 2 minutes. One of my neighbors slamed their door, resulting in the bracket breaking.

I would think reverting back to your XP installation would help you eliminate any potential hardware problems. Alternately, make a bootable Linux CD (Ubuntu for example) and boot from that... no reason to do the install... that LIVE "installation" will help you verify your hardware is in good working order without having to overwrite your existing Windows install.

HI Enthusiest gamer ,

When you do your clean install did the HD are reformat. What format size did you choose ntf ?
You can remove the partition during installation and put it back again that way you will be sure hd is clean and freshly reformat or I think during the installation process you can specify to reformat the HD .
In your post you said you don't install or remove other physical component. I will be really surprise if the power consumption should be altered by a different OS ?
The last think I could see is in the bios of : what mode did you used too run your disk achi ide raid ... May there is something there.
Thanks and sorry english not my first langage

Well i popped in the old Ubuntu live CD and it crashed as soon as it got to the desktop part. Thinking its the PSU i took the gtx 260 out and had it run on integrated, which should mean less power consumption, right? Same result. Maybe its the Mobo i dont know...It worked fine up until i installed W7

Enthusiest Gamer,

Prior to migrating to Windows 7 from Windows XP did you run the Windows 7 Upgrade Advisor?
To determine if your current computer configuration will be compatible with Windows 7 please go to the following link:

Another resource to verify compatibility is available at the Microsoft Windows 7 Compatibility Center located at the following link:

Another question, have you recently upgraded any hardware by chance?

Also, Microsoft does have an official Windows 7 Support Forum located here . It is supported by product specialists as well as engineers and support teams. You may want to also check the threads available there for additional assistance and feedback.
