newprouser Posted March 17, 2010 Share Posted March 17, 2010 I'm using a windows 7 Ultimate, x86 which stops working randomly without any reason.since the problem always occured when i was away from the desktop i'm not able to tellwhat exactly happened . I just leave windows is running, and return back to find thatthe monitor has gone into power saving mode and i found that the CPU was still poweredon but there was no HDD usage at all.There is no response to any keyboard or mouse activity.Initially i felt it could have been because the PC had gone into sleep because of power options, but then the CPU is still on.Upon on pressing power switch it INSTANTLY shuts down.--I doubt this could be due to 3rd party software incompatibility, because i haven't installedanything new in the past few days.

Tripredacus Posted March 17, 2010 Share Posted March 17, 2010 Most problems with Windows are usually present longer than you'd expect. Things do not typically "just happen" out of nowhere. Your first place to look for clues would be in the Event Viewer. Link to comment Share on other sites More sharing options...

cluberti Posted March 17, 2010 Share Posted March 17, 2010 After it shuts down, if you power it back on does it give you the "recovery" menu (start windows normally, safe mode, etc. options), or does Windows boot normally? If it's the latter, it sounds more like the system is failing to go into a power-saving state properly (probably hibernation failure, as is common with BIOS power-saving issues). Running "powercfg -h off" might change things, and is worth a try if this is the case. Link to comment Share on other sites More sharing options...

cluberti Posted March 17, 2010 Share Posted March 17, 2010 OK, so it is a failure to sleep, although the immediate shutdown is the wildcard. Assuming you have the latest motherboard BIOS for your system, and it implements the S1 and S3 states properly, it might be best to test to get a trace of this and see what's happening, as it seems something (driver, perhaps) is causing the failure to sleep.

newprouser Posted March 18, 2010 Author Share Posted March 18, 2010 (edited) I ran the trace for hibernate mode, and the trace dump is about 81 Mb (~20 compressed) ,do you want me to host it somewhere and pm the link ?---btw i forgot to mention that sometimes i've had issues when resuming fromstandby - the monitor would be on , but will only display an entirely blackscreen. so i'd usually put it to standby again and resume it, it would befine.so your guess of a driver issue seems highly probable.

newprouser Posted March 19, 2010 Author Share Posted March 19, 2010 (edited) Bug trace:http://www.mediafire.com/?jgnij2d2l4m---Got a shiny new BSOD today :'(BAD_POOL_CALLERSTOP: 0x0000000C2 (0x00000007,0x00001097,0x8AFOBB64,0x852DD730) Edited March 19, 2010 by newprouser Link to comment Share on other sites More sharing options...
cluberti Posted March 19, 2010 Share Posted March 19, 2010 Bad Pool Caller would be a driver issue, so more fuel on the fire. If you want to compress and post the .dmp file it created, that'd be good too. Link to comment Share on other sites More sharing options...
newprouser Posted March 19, 2010 Author Share Posted March 19, 2010 well for some reason i had previously set a full memory dump, so its a ~2 GB dump now could you tell me what i've to do to analyze it ? i do that and post the results...--meanwhile should i change dump setting to minimal or kernel dump , just in casethe BSOD happens again i could post the kind of dump which you want.

Tripredacus Posted March 19, 2010 Share Posted March 19, 2010 You can try analyze it yourself using the Debugger tools for Windows. You also need to get the symbols for your OS. Even then it can be confusing if you don't know what you are looking at. http://www.microsoft.com/whdc/devtools/debugging/default.mspxIf you can upload the dump file, there are a couple users here that can read it for you.
