Hi,
I have been having issues with my laptop for a while and have exhausted all attempts to fix the problem. I was hoping that some of you could either help me out or point me in the right direction
I would post my computer specification but when I run the 'dxdiag' run command the System Model, Manufacturer, Bios & Processor all show N/A. I do know that the laptop is a Lenovo Z585, has 8gb of RAM and a AMD Radeon HD 7660G + 7600M Dual Graphics Card.
I originally had issues a month or so back (the laptop all of a sudden started to crash very frequently). I sent the laptop back as it was under warranty and they replaced the RAM, motherboard and performed a BIOS update.
I received the laptop back at the start of December. All seemed to be fixed, until I upgraded to Windows 8.1 (was running Windows 8).
After upgrading the computer started to frequently crash. I looked at the crash dumps, found a couple of drivers at fault (was an out of date wireless network and graphics driver causing the issue). I updated these and the problem stopped.
However, after a week or so the laptop has started to crash again. The laptop consistently crashes twice a day (with around 8-10 hours of use a day), but these crashes come at varying intervals - sometimes 30 minutes apart, sometimes 5-6 hours.
I have updated all of the drivers that I can to the latest versions, ran memtest and it came back with 0 errors. I also checked the hard disks and these also came back with no errors. I also have no antivirus installed.
Unfortunately 90% of the time when the computer crashes it randomly restarts. The screen goes black and just restarts. This means that I only have a couple of crash dumps as it has only actually crashed with a BSOD twice in the last week.
Most of the crash dumps seem to occur when I have set the power plan to 'high performance' and am playing a game, but this does not happen all the time so I don't think I can attribute the problem to this.
I am not over clocking the system in any way and have barely changed the default settings.
The couple of crash dumps I do have show the driver that failed to be usbhub.sys and ntkrnlmp.exe (the second one has shown up a lot in the previous BSOD that I was getting). I'd be more than happy to upload/post the crash dump files if somebody would be kind enough to let me know how.
I'm new to the forum so have tried to be a descriptive as possible and included everything that could be useful.
Any help would be greatly appreciated
