2 or 3 times (less frequently than BSODs) the PC freezes / locks / stops. Nothing happens, the mouse laser goes out. Has to be powered down and rebooted.
Apart form the NIC and USB3 drivers, all were loaded by Windows itself.
The most recent install went BSOD during the actual install "Finalising Installation" phase, long before I'd had chance to do any localisation. The dumps, as far as I can see, point to any specific faulting item.
This installation BSOD made me think of hardware issues - despite the PC running XP Pro fine for 7 months.
Basic System Spec:
CPU: 2.80 gigahertz Intel Core i5 760
Motherboard: Gigabyte Technology Co., Ltd. P55-USB3
Memory: 4 Gbytes - 2 x 2Gbytes Hyperam DIMMs
Graphics Card: NVIDIA GeForce GT 430
Sound Card: Integrated
Hard Drive: 1 Tb Seagate ST31000528AS (partitioned C: 150Gb / D: rest)
I've twice run MEMTEST86 overnight - no problems found.
I've twice run Hiren's HDD Scan - no problems found.
I've reset the BIOS to Optimized Defaults - still BSODs.
I've swapped the memory modules round - still BSODs.
I've run on one of the two memory modules - still BSODs.
I've changed the BIOS Performance Enhance option from Turbo to Standard - still BSODs.
I've also reset the BIOS to 'optimized defaults'.
I'm beginning to run out of ideas as to what it might be.
A friend wondered if it was a 'bad' copy of Windows - it's the full retail version purchased from Amazon UK.
I've posted all details and diagnostics on the Windows 7 Forum, though nothing back as yet.
Any help/thoughts would be most appreciated.
