My Windows 7 computer since about a month or so started freezing/rebooting. I have it since 6 months, and before was running fine: I believe could be some Windows or maybe video card update.
When it freezes the screen is black but because I have the monitor suspended after 30 min. So far it always happens when I'm away - it never froze when I am using the computer.
I checked event and saw the error: Kernel-Power ID 41 (63).
The other info is:
EventData

BugcheckCode 234
BugcheckParameter1 0xfffffa800c7ef040
BugcheckParameter2 0x0
BugcheckParameter3 0x0
BugcheckParameter4 0x0
SleepInProgress false
PowerButtonTimestamp 0

Does anyone know what it could be in specific ? thanks

ignore the power error 41, you will get one logged after any power failure or bugcheck you get.
it just means the machine restarted before it completed all of windows shutdown routines. it is logged on the boot after the failure.

bughceck code 234 = 0xea = Bug Check 0xEA: THREAD_STUCK_IN_DEVICE_DRIVER

tends to happen a lot with graphics drivers.
anything that messes up the graphics drivers timing can cause it.
things like, motherboard audio conflict with the GPU HDMI sound support.
- old network drivers can mess up nvidia cards to the point they hang.
- old bios versions
generally, you update the BIOS and motherboard drivers to the current versions. or go into BIOS and change any setting and change it back if it is already current...

For that error code, yes. You can try checking for a BIOS and driver update for the motherboard and video card, you can also try a clean new Windows setup to rule out any software issues if you want to take the time for that before testing the card in another system.

Well for now I'm doing something that SEEMS to work: I disabled PC auto-suspend (it's always on all the time since I work so not a big deal). I also replaced the monitor suspend with a screensaver, and it never froze since then. Weird, but seems to work!

generally, you update the BIOS and motherboard drivers to the current versions. or go into BIOS and change any setting and change it back if it is already current. Then you save the settings and reboot. this forces the BIOS to rescan the hardware and might resolve certain hardware conflicts.

overclocking drivers for the GPU or CPU, power fluctuations, certain hardware devices that share the PCI/e bus. lots of reasons for this error.
sometimes likely causes can be detected from the memory.dmp file or the minidumps. the fix is generally the same, update the BIOS, and motherboard drivers, remove overclocking drivers. The memory dumps can help pinpoint old drivers that should be updated.
