Windows 7: Random system lockups

Random system lockups

Over the last two days I have had four system lockups, not BSODs.

I have been using the system normally and then the screen goes a single solid colour, seems to be related to what is open, so went green one time when I had Freecell open although this was not the active window, and the disk light comes on.

I am unable to access the system through the keyboard and I lose access to the drives, etc. from another machine. So far I have left it for 15 minutes before having to press the power button to close it down.

I've checked all the logs in eventvwr and there are no error messages relevant to the time of the lockup. although on two of the four occassions there are error messages for the CDROM, but they are at least half an hour in advance of the failure.

I've scanned for viruses with no result and checked the disks with no errors. CPU and MB temperatures are slighly up, but well within limits and consistent with the room being hot.

The system has not been updated recently and there have been no hardware changes for months and no dump is being produced as techically it is still running.

I'm running Windows 7, IE9 and McAfee antivirus and firewall 10.5.240, the graphics is an onboard Nvidia 8200, all are fully patched. The machine is an AMD 9950 quad core with 8Gb memory. The system is not overclocked.

I'm not sure what info to provide, so if anybody has an idea what this might be or wants further info, please let me know.

Thanks in advance.
