Viktors - I have emailed the info across to you as requested.
----------------------------------------mycrofth - I need your help on this one as I am not sure how to monitor the system on-line, short of sitting and staring at the screen every time I estimate a WU to finish. I did catch one - at 17:12 GMT+2, the points changed from 67399 to 67576. Unfortunately the stats are cumulative for the day, so I cannot identify individual postings of data / points. My observation is based on the data I have in MY GRID, which show that the daily average for the ROBERT standby device are dropping daily and yet this machine does nothing else but crunch data. My gut feeling (but then again the gut is what links the "loud mouth" with the orifice at the other end - so it is half way between BS and real .... ), says to me that there are errors in the data I am sending back (caused by the memory problem I was experiencing two months ago) and the data is being rejected and therefore no score being applied. . . .. but like I said - gut feeling! As far as I am bothered by 'not rebooting'. You DO occasionally reboot this 24/7 system, don't you? After all, Windows is notorious for strange memory leaks, etc., caused by all those different device drivers and programs from different manufacturers. is concerned.... I have NO REASON TO DOUBT YOU ON THIS!!..... but rebooting a machine that does nothing else then crunch data ... hmmm I will try it - only the unpredictable is foreseeable when it comes to microsoft. sorry for not getting back to you earlier, the winds were up this weekend, so it was time to do some:  back on-line now.

Hello, RobSab.
Now that you have sent in a 'Contact Us' report, we can expect that any results being rejected because of errors will be spotted by a machine-specific query in the database. So we can prop our feet up on the desk and think. My main reason for occasionally rebooting is something of a compulsive tic. The software in a modern PC comes from all over and does not fit together perfectly. I think that it was in February that I tried to update Windows on the second Tuesday and could not, until I remembered that I had not rebooted for some days. So I rebooted and then I updated my Windows XP system with no problems. That is the last time that I had a problem that a reboot solved. Still, I expect such things to happen 2, maybe 3, times a year. After all, at least once a week my anti-virus and anti-spyware programs are updated on the fly. So my system is not really static. Mysterious slow-down in points awarded. Hmmm... Well, errors invalidating results or causing hidden reloads of Rosetta are one possibility. Another is a temperature-mandated slowdown. A third possibility is interfering software, either legitimate (daily scheduled scans for malware, network backups, Spinrite checking your hard disk drive, etc.) or illegitimate (malware running on your system, reducing the CPU utilization of Rosetta). I think you would have found any software problem. So right now, I am content to wait and hear what the server check turns up. It's a nice day here in South Carolina, with just a brief shower at noon to keep everything green and growing and not too hot. mycrofth |

Thanks mycrofth. Your posts always inspire me to get out of the box and take a look from the outside - in!
Did a check list on the issues you raised, just to make sure that they are being addressed. This is the outcome: Software: XP home edition with SP2 and current updates (auto option on) Applications: Symantec firewall and antivirus – updated automatically Spybot – which I run once a week manually as Nortons does not seem to catch spyware well. This application is recommended by Microsoft. MS Office – fully updated (the machine is a standby computer, so everything is ready for use, but the machine is not in use – i.e. runs wcg agent and nothing else) Hidden reloads of the Rosetta – I have no idea how I can track that. Hopefully the monitoring of my results by wcg will give some indication if this is taking place as information on what my device downloaded and what it returned must be stored somewhere. Temperature – I run speed fan every now and then to check up on the temps. When I initially started the agent, the processor (AMD64 1,8 Gig) was getting hot. Installed a thermo regulated fan with a new heatsink on the processor and upgraded the VIA chip set heatsink to a larger one. Now the temps are as follows: Processor 48 degrees C Chip set 31 degrees C Hard disc 40 degrees C These are all within the nominal working temperature range, so they do look ok. btw they are very stable +- 1 degree variance day-to-day Regular routine processes: scans for viruses and spyware – all set to manual Backups – I am not backing the system up as it is in standby mode. No changes as no work going on here apart from wcg agent Spinrite – I don’t have any knowledge on this. Illegitimate stuff like malware – I do not know how to check this. I had assumed that Symantec and Spybot would handle this. I hope they are ???? I will wait for feedback from the server checkup – this should be revealing. What is interesting is that the agent still ranks the PC high (processor at 180, overall at 145 – has not changed a bit)… and yet the daily points average has dropped over the last two weeks. Not only has it dropped, but is unstable (92 one day and 629 on another. Previously it used to average between 500 and 700 a day) I must admit, that in the back of mind I am asking myself if this “problem” is a system wide problem, then can it be what is causing the grid progress rate to slow down….. But let us get the results of this specific issued first before our imaginations get the better of us. hope your weather holds out like that for the summer! |

Viktors has been spot on identifying the problem. It seems that my standby PC's processor has a floating point error. This does not efferct standard microsoft applications that are usually run on it, however it does effect the agent.
As a result of this problem, data is being sent back to the grid after crunching, however it is recorded as crashed data and therefore unusable (I presume) Aparently I need to replace the procesor - and AMD64 1,8G. I cannot spend that money on a new processor at present, so I will be forced to power the PC down as it is really not being very efficient crunching 24/7 for 90 - 250 points a day (sporadcally more). Sorry guys .... I will have a go at swapping my PCs out and using the standby for my everyday work and letting my main PC do the main crunching, however this will take a while before I reconfigure the equipment. meanwhile - thanks for all of your assistence and guidence. It is very good to know that there are noble people out their involved in this project that are willing to give up their personal time to help others. Thankyou. |

How misleading can things be.
This is a follow up to the problem I have been having with a PC (details and summary in previous two posts).
 2. Bought new memory (2 x 256 DDR PC2100) as they are cheap, but got some kingston and .... problem came back !! 3. Got onto the motherboard manufacturer's web site - downloaded new version of BIOS ..... same problem!!! Googled the problem .... and someone recommended taking out one memory stick ... problem went away - PC runs stable wth one memory bank only. Chcecked the connectors, tried one stick in every bank. Tried a different stick - single sticks in all slots work fine  ... so I am running with 256meg and crunching away..... very confused. My intuition tells me that the power line on the motherboard to the memory is playing up - on load..... but who's the wiser?. Not me. I am going to crunch on with 256meg . . around 450 points a day .... will have to work. Shame though as this is a AMD processor and was providing up to 800 points a day. I hope this help someone, somewhere resolve a similar problem... |

Problems With Mouse?????? You might want to update your virus scanner, Check in with Windows Update, and read this..
----------------------------------------Plug and Play pandemonium I've read the exploit being used is also found in some XP systems.  There is a link in the story that will take you to the MS Security bullitin.I've also read the it can affect the mouse behaviour or kill the critter all together. |

I am also assuming that there are not two different computers for member RobSab with the identical device name. Duplicate devices can cause weird things to happen.
----------------------------------------It can be checked in the device manager in "My Grid". Make sure the picklist is set to all devices installed/registered anytime (all devices). That will pick up the names of any old ones you may have forgotten about.

I have one user RobSab, two device profiles ( I only use one - the other is dormant) and three devices with different names. I have pinpointed the issue to one PC now - the issue is one of the motherboard only working with one bank of memory. The thread title is somewhat misleading as that is what hte initial problem showed up as. [Edit 1 times, last edit by Former Member at Aug 17, 2005 8:24:18 PM] |

The thread tytle is somewhat misleading as that is what hte initial problem showed up as. There's an easy solution to that one.  Edit message 1, the first message in the top of the thread on the first page. You, as controller of the thread, can change the title to whatever you want if you see new conditions you need to help you with your problem. I have pinpointed the issue to one PC now - the issue is one of the motherboard only working with one bank of memory. Could there be 2 different brands of memory that will not coexist, perhaps?What happens if one bank is removed, as a test? ... or put it back and remove the other? That would just show that one bank works, and whether the spontaneous interruption problem goes away. Has the memory been tested with memtest86? I really suppose I should read some more in this thread before coming up with more questions...
