BSOD on restart, boot and during Skype video call
Hi
I've had 3 BSODs since the end of January - 2 of them yesterday. The first happened during restart after the system became unstable and would not load any Firefox pages or allow me to close it or stop any processes. I wasn't in the room at the time.
The second happened on boot and whilst I was out of the room, so not sure how far it got before happening.
The third happened a couple of minutes into a video Skype call yesterday. After reboot I was able to resume the Skype call, (although with just video on my side of the call (not receiving video) - we didn't try video on both sides)
System Details:
Model: Dell XPS L702x
OS: Windows 7 Home Premium 64 bit
Processor: Intel Core i5-2410M CPU @ 2.30GHz
Memory : 6GB (1X4GB + 1X2GB) 1333MHz DDR3 Dual Channel
Hard Drive : 500GB Serial ATA (7200RPM)
Windows 7 x64, originally installed on the system, OEM.
System is about 10 months old and so is the OS (no reinstall)
The laptop is always hooked up to a Samsung SyncMaster B2230 external monitor and a Buffalo Ministation external drive.
The first BSOD happened a day after allowing a McAfee technician to remotely reinstall McAfee Internet Security and 4 days after installing Photoshop CS5.
I don't know whether this is related or not, but I regularly get a problem where there is a time-lag when I am typing or before I can click on a Firefox link (though this may be Firefox). There's also a problem with McAfee intermittently using up to 84% of the CPU, so I dunno if that has something to do with it...
I've also had a few system freezes accompanied by a rhythmic squeak that sounded like it could be coming from the hard drive. IIRC there was one BSOD that happened during one of these times, though I don't think the dump file for that one is available. This hasn't happened for a few months and seemed to happen when playing music via Windows Media Player. I ran chkdsk and it didn't find any problems.
Any help would be gratefully received because I don't have a clue to fix this
