Dell Vostro 3500 intermittent freezing

1st time posting.
I've got a Dell Vostro 3500 that will run for a day or so, it will sit for a weekend, and it's fine. Then it will just freeze.
I spoke will Dell and went through all the hardware tests which it passed.
Then I re-installed Windows 7 Professional. And I installed Office 2007.
It sat on but unused for the weekend. I came in and was happy that it was still running. Later that day it froze again under no load. So I installed Speedfan with the suspicion that it might be overheating and if it did freeze I'd get the temperature readings from when it did.
This morning, with Speedfan still running I opened Word and closed it, no problem. Then I opened Outlook and before I could start to configure it the machine froze again.
So I checked the even logs, nothing in Applications and nothing in System.
We've got about 30 of these Vostros at work here and nothing like this has ever happened with them. I am at a loss on what to do next.
Maybe the power supply is sending a jolt through the system and causing it but I have no way to monitor that.
Any suggestions will be gratefully welcome. Thank you.

Monday morning: did not wake up from it's weekend nap. Fan was blowing but the screen was black. Powered off then on and checked event viewer and no error messages for system or application. However the last entry in application was: "The description for Event ID 0 from source gupdate cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on your local computer." But the previous event stated that the service was started. And it was the exact same time stamp.
I am truly at a loss.

Disabled turning off the HDD yesterday. So now if it's on it's running - no sleep, no hibernation, just turn off display. It sat overnight and was fine this morning.
Will continue testing but disappointed in the lack of interest from this community.

Screen was black this morning, pressed "Enter" and there was my desktop. Left it and went back to work. Then I noticed that the clock hadn't changed, frozen.
Application Event log: ERROR "Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected."
Nothing in System event log,
