PC crashes when entering sleep mode, claims a BSOD failure
Hi.
My PC used to be able to enter and leave sleep mode without any problems, then about a couple of months ago it started failing every time, whether I command it to sleep or it sleeps due to power options. I haven't made any manual changes to hardware or software that could have caused it, but there have obviously been plenty of Windows updates in that time.
When the PC tries to go to sleep, there is no visible BSOD. It seems to take the usual steps (i.e. warns me about software preventing it from sleeping, then shuts them down) before the screen goes black, but from that point it takes about 10 minutes (during which the hard drive activity light flashes most of the time) before it finally powers off.
When I power the PC back on, instead of it resuming Windows, I get the early boot menu telling me that the system didn't shut down correctly and asking me to choose a normal/safe boot. Once Windows has loaded, I get a "Windows has recovered from an unexpected shutdown" message similar to the following:
Hitting the "Check for a solution" button gives me nothing of use (it actually tells me nothing at all, usually, not even confirming that it's managed to check anything at all). I've looked at the minidump but I don't know enough to know what I'm looking at or know whether it's of use.Code:Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 2057 Additional information about the problem: BCCode: 9f BCP1: 0000000000000003 BCP2: FFFFFA800557D4D0 BCP3: FFFFF80000B9A518 BCP4: FFFFFA800D452600 OS Version: 6_1_7601 Service Pack: 1_0 Product: 768_1
Any help would be much appreciated. Thanks in advance.
Neil.
