Windows 7: Blue Screen or Computer Freezes

14 Aug 2012   #1

Windows 7 Home Preminum 64bit
Blue Screen or Computer Freezes

Hi everyone,

I hope someone here can help me out because i'm getting stuck trying to debug this issue.

Blue Screen Information:
A process or thread crucial to system operation has unexpectedly exited or been terminated.
Technical information:
*** STOP: 0x000000F4 (0x0000000000000003, 0xFFFFFA80190D3B30, 0xFFFFFA80190D3E10, 0xFFFFF800039D4510)

I have read that the dump log file should be stored in Windows/Minidumps/ folder or directly under the windows folder called MEMORY.DMP but there have never been any such file created in all my crashes even though i have changed the settings from kernal dump to minidump and back and forth.

The computer gets blue screen or hangs within 0-60 minutes.
The problem has occured when i am webborwsing, watching video or gaming.

When the computer hangs, the orange load button on the computer is lit up constantly suggesting the hardrive is working nonestop.
I did some monitoring of when a freeze occured, it seems that there is a spike in activity CPU and HD then it goes dead and shortly thereafter the HD load goes to 100% all the time, dipping down brefily to 98% really fast then back up again.
After blue screen occurs, the computer has a tendancy to set my set my bios setting incorrectly. Trying to select my sotrage drive to boot before my SSD main drive. This result in a "reboot and select proper boot device or insert boot media in selected boot device and press any key" message at startup and i have to enter bios and fix this by setting SSD disk to boot before my storage disk.

What i have tried:
* Opened up the computer to see if some cords where disconnected or loosely connected, reconnected and disconnected some of them.
* Checked all FANs was working and spinning.
* Disconnected DVD drive & Burner and reboot.
* Disconnected & Removed my storage HD.
* Ran memetst86+ overnight on RAM, passed 5 times without any errors.
* Ran chkdsk on my SSD disk with windows 7 installed.
* Tried backup from a previous dates 2 times.
* Done recovery 2 times, wiping any information on the SDD disk with windows and resetting to factory defaults.
* Plugged power cords directly into the walloutput, instead of going through extention coord with multiple connectors.
* Monitored any oveheating issues with speedFan when problem occured, everything was stable at around 30-60*C
* Updated Graphics drivers.
* Checked the event viewer, but cannot see any errors, warnings etc when the crash occurs. Can only see a Critical: Event ID: 41 Task category: (63) but all event data is 0. The error just indicates: The system has rebooted without cleanly shutting down first.

Windows 7 Home Preminum 64bit

Hi again,
After countless more hours of debugging I seem to have things up and running stable now again.
What i did was install windows 7 on a new SSD disk which i wasn't using, tested using only that disk installed and everything worked fine, got no freeze or bluescreens.
I then added my storage drive, everything still working fine.
I'm planning to try to use the old SSD disk as storage now instead and see if it works, if not i'll just throw the disk away.
So i've removed all partitions from the old SSD disk, formated it and updated the firmware as suggested, hopfully it will work and not cause any more problems.
So to conculed it seems that there was somthing wrong with the SSD disk, i'm not sure what at this point could be the old firmware that was bugged or became incompatable.
So if you have problem like i posted above i suggest you:
a) Try to update your harddrive firmware.
b) if a doesn't solve anything, try removing the windows disk and install a clean windows on another disk and try running with that disk only.

As an extra note, i noticed that my bios was set up to run the disks in RAID mode when i was fiddeling with the firmware updates.
This seems to be the default setting, since i haven't got my disks RAID configured i decided to switch to AHCI instead which seems more reasonable. I'm not sure if this was contributing to my freezes and blue screens somehow as well.

Hope this helps anyone else out there.
