My home pc freezes when doing energy or water tasks. Seems to get to a point in the task and it freezes, then on reboot will freeze again at around the same point.

Then I had to swap out my screen for a lower res one and it seems to be back. Either that or windows update did something. I'm running diskeeper and shadowprotect. Any ideas? |

Suggestions:
Check your Event Viewer system log for "Bad Spot" entries. If you have any, this would indicate a problem with your hard drive. http://maximumpcguides.com/windows-7/how-to-c...logs-in-the-event-viewer/ From a command prompt run DOS command CHKDSK to check the file structure of your OS. http://www.windows7hacker.com/index.php/2010/...dsk-command-in-windows-7/ Also check the memory, here's one tool: http://www.memtest.org/ Windows 7 includes a memory checker: http://www.tomstricks.com/how-to-test-your-ra...nostic-tool-in-windows-7/ |

We'd be most interested to know the [exact] type of messaging found and the final root cause finding, so it can be documented in the FAQs. Concur that if the fail is always same spot and the system is/has not been doing anything else that RAM or HD sectors are suspect.

Also forgot to mention, probably a good idea to reseat any memory DIMM sticks. Slight heat creep can make at least one side move up thus causing potential problems. There are clips on sides of the DIMM in some instance may not be fully upright in a secured manner.

OK here's what I've found out so far.
Took pute to technician to investigate event logs re ntfs corruption and communication with device errors. He tested the drives, no errors and told me that the errors were not the result of hardware failure/s. I ran checkdisk a couple of times, no problems found. So I test a work unit in isolation (clean energy) and it causes the computer to crash in almost exactly the same spot (give or take a couple of seconds). When i disable WCG the ntfs errors stop. However the device communication errors remain. So then I disabled diskeeper and those errors disappear too. I have a suspicion that diskeeper doesn't agree with shadow protect and is causing the communication errors. And when this happens WCG throws the ntfs errors. I will test how WCG behaves with diskeeper disabled and report back.. |

Clean energy is very disk intensive at certain points. It's possible that the combination of that project and diskeeper is overwhelming the capacity causing the freeze.

Kinda sounds like a diskeeper problem to me. I have never had any issues with Shadowprotect...of any kind and I run a lot of both Boinc and Shadowprotect.
