Restarting Win 7 unexpectedly after 1-2 hour

[dzgraphix]

Hello there,

I'm using Windows 7 Ultimate 32 bit from November 2009. It was running smoothly and I like this OS very much. But from yesterday it's restarting unexpectedly after 1 or 2 hour. No bug report, no Blue Screen, no HDD or driver or device problem. I've checked everything and it seems everything is working well. It's very irritating when I'm working and restart the PC unexpectedly. I tried to find out the problem but failed. So I thought here must be someone who would be able to find any solution.

My PC configuration is -

intel core 2 duo 2.66 GHz
RAM 3 GB DDR2
Intel 31 PR motherboard
Built in sound card and graphics card
2 HDD a) 320 GB Samsung b) 80 GB Samsung

Oh, I'm using Windows Vista also in same PC and currently using this and there is no problem with Vista. It's working well.

I've checked all HDD by Kaspersky Internet Security and Malwarebytes; two of them couldn't found any virus or malware or whatever harmful for PC.

means that you have the beta build and not the official release. if you think that its full. then next time buy in store. dont use torrents..

It sounds like you are using the RC version of Windows 7 which has expired. You need to upgrade to the retail version. The RC version will shut down every two hours until June, when it will cease to function. Back up your data now and upgrade to the retail version. Hope this helps...

If you don't want to upgrade, go to your BIOS settings and set the date back to Year 2009, and prohibit from entering March 1st, 2010. Remember, you won't be able to use Windows Update anymore if you do this.
