Gentlemen,

This machine was built about a month ago, burned in using one of the BOINC applications for about 10 days, and generally showed good operational reliability.  The computer was installed at the customer location, the BOINC applications uninstalled, and generally showed good operational reliability.  

Note that the computer has a 500GB hybrid hard drive, Seagate Momentus XT.  Video card is PowerColor Radeon HD 5750.  Serial card (which came with unsigned 64 bit drivers, but WindowsUpdate replaced them with signed ones)

As the symptom and sequence is being reported to me, after the computer is not being used for a period of time, the screen will go blank (black), is allowed to remain unused from 15 minutes to about a day, then when the mouse is moved, the Windows desktop appears, the moving mouse can be seen, but clicking on an application will not have an effect.  The hard drive activity light will flash regularly (about 1 per second).  


What I've done so far:

Power options are set to "High Performance".  
Turn off display after: 30 minutes.  (have changed this to 0 now)
Minimum processor state: 0% (this was set to 5% while the machine was being burned in, but all cores on the processor were running at 100% sustained)
PCI Express link state power management = Off
USB Selective Suspend = Off
Hibernate = Never
Allow Hybrid Sleep = Off
Sleep After = Never
Slideshow = available
Turn off hard disk after = 20 minutes (just changed this to Never).


Have reviewed the event log, and no interesting error messages were being reported, other than a long string of identical error messages relating to "schannel".  


My question: How can I learn more about how or why the machine gets into this comatose state of being technically alive but unresponsive, and how to solve it.  


Thank you in advance for your help.

My bet is it's a problem with the hard drive , I was looking into buying a couple of these drives(raid0) but found to many negatives. Sure they are fast but they have a high failure rate, and a bug in the firmware that has issues with power management and can cause lockups whens they system is idle. Hss it locked up since changing the Turn off HDD to never? Seagate was suppose to be looking it to an update the fix the issue so you may want to check their site for a firmware update.

you can test the issue by installing another disk
another way of diagnosing is disconnecting all devices not needed :
extra disks, all cd drives, disable sound in bios...

Gentlemen,


Good ideas, thank you!


No news yet on whether the machine has locked up since yesterday.  Will send a message to the customer and report findings.


I checked the Seagate site here:
http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207931&NewLang=en
There is no indication of any firmware updates on this page for the ST95005620AS drive.  Is there another page you were thinking of or might suggest?

No surprise, but I'd rather not run as fast as I could and embrace replacing the hard drive like I haven't seen my spousal unit in 5 years.  The source disk is 500GB; but squishing and cloning to a smaller drive would finish in a reasonable length of time.  I haven't tried to create a bootable drive in the larger-to-smaller direction.  Thoughts on doability?

I recd a report from the customer today, saying that the computer has not become frozen again since the last service and the above three "done so far" changes were made.

Requested continued periodic reports of new news and no news.

Ironic, perhaps.

I have an iPhone, which notifies me with a Mrrp! Whenever a message is recieved.  Even on Sunday.

Since this problem was intermittent, more grace time was appropriate to see if the last changes had a durable effect or not.

I have been in contact with the customer, and the problem has not resurfaced.

Thanks for the human follow through.

The three "done so far" changes, which relate to not transitioning to different power conservation states, were effective and durable.

Thank you.
