Random freezes with windows 7 - 64 bit

Memory timings did not fix it for me or some of my customers, although it has on some other systems. So yes in some cases your advise should be heeded but in others it has already been tried.

--> Hope this helps! Please voteor mark as correct answer if it does :) <--

Everybody has different solutions and theories about what causes the problem. I do also read and try to figure out the problem I´ve had no success so far.

The problem is that there is no trigger to this. Microsoft support talk about do a safe boot and see what driver or program is causing this. But I can´t find such a thing. I can use the computer have MSN on, surfing the news site, Facebook, you tube and so on without any trouble and then a minute, an hour or a day later the computer freezing, without any change in activity, the same sites, the same programs. Sometimes I can boot the computer and only open up Media player and play some music. I don´t use any other application. The music plays for a minute to several hours and nothing happen and then suddenly the computer freezes.

Sometimes I can have 7 computer freezes in an hour and the after last reboot the computer works fine the rest of the day. And now the computer starts to rebooting al of a sudden.  

And I have not had a single blue screen, the computer freezes and i can´t do anything but reboot, can´t use any keyboard commands.

This is really annoying and in the lack of better words: WTF?!?!?!?!? :/

That's because based on where the written memory is stored on the memory chip it will crash the system randomly. Hence all the chaotic confusion of various systems and complete randomness. The one thing that can NOT by any means be determined is where in the ram chip the code is going to end up. Its the speed (frequency), voltage and timings of the memory chips in relation to how Windows 7 does (or does not) correctly handle elevated memory speeds that is the problem. I feel like I am beating my head against a wall as to why PPL DO NOT LISTEN TO MY ADVICE THAT ITS THE FREAKIN MEMORY TIMINGS!!!!! Bump that s h it down and try it what have you ppl have got to loose? I have now posted about 12 posts in various threads thatSPECIFICALLY deal with this issue. I have had this problem since October of '09 and fixed it (although running my system in gimped memory speeds) It's STABLE so listen to my advice at your peril if u do not!

I've been having the same problems for about a week now...since installing Win 7.  I get random system lock ups where I can't do anything.  I don't get the BSOD.  I can't alt-tab to another process.  I can't ctrl-alt-del to bring up task manager.  My mouse courser will switch to the busy icon.  Sometimes I'm able to move the mouse courser but as soon as I click on anything it freezes also.  The only way to get out of it is to hard reset.  A lot of times when I do this windows won't complete reboot.  I'll get "A disk read error occured press ctrl-alt-del to restart" message.

I checked the Event Viewer for errors.  I got a bunch of warnings and these two Error/Critical events:

I got this error event (2x today):
