Windows 7 keeps freezing

Hi,
I have a problem with my windows 7. It keeps crashing at random times.
I had 3 crashes yesterday and 2 today so far.

I tried to search for dump files to check the problem but couldn't find any, there is no minidump folder either, so what is the deal here?

If I go to the "view event logs", this is what I am getting:

Critical 09/08/2009 11:08:22 Kernel-Power 41 (63)

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Code:

I am using this version Win7.7600.16385.090713-1255.X86FRE.

And if you are wondering if this is a hardware problem then no cause on XP my laptop works fine.

And it is not that the heating up of my CPU cause while I was checking the temperature which was 46c using speedfan.exe the screen froze, I can still hear the HDD working as well as the fan.

Another problem which is a minor one is the sleep mode, once the laptop goes to the sleep mode, I can't log on to windows again, I have to force shut down by keep pressing on my power button and if I switch it on again it won't boot, so I will have to unplug my AC cable and plug it in again, then I will have a somehow slow boot but eventually it will work.

The freezing problem happens sometimes after 30 mins and sometimes after several hours, plz help me

I have 2gb or ram and now I have 7gb of free space. I set it to capture 128kb dump files and specified the target folder.


I ran the tool from microsoft and it showed that my system is compatible except the sd card slot, but once I installed win7 I updated the driver and everything seems to be fine.

The secure able showed this:


I can't do much about the third feature as my processor doesn't support it, the second one is turned off by my mobo, I can only install bios updates from toshiba's website.
I went through my bios, nothing there to support the second feature.

My laptop is Equium A110-252 and it is designed for Xp but it has a "windows vista capable" logo, besides it has all the required updates for vista on their website.

EDIT:
I managed to fix the second feature

Use this tool -Dump configurator Windows Platforms Tools to diagnose issue with creating dump files

Update:
The problem was google chrome, uninstalled and now no more freezing

I know mate, I was shocked myself.
After one week of experimenting, it came down to two things, adobe flash player and google chrome.
I used Firefox 3.5 + adobe flash player and nothing happened till this day, it's been more than 3 days without freezing :)

p.s. The sleeping problem was because of the copy of win7 I installed, I guess it was corrupted or missing some files, and now no more sleeping problems.
Awaking my laptop takes seconds, I am so glad it worked out finally as I love win7.
