Since June, I have had intermittent BSOD's. I kept a record of them
8 July - VISTA_DRIVER_FAULT
10 July - CODE_CORRUPTION
12 July - CODE_CORRUPTION
26 August - IRQ_NOT_LESS_OR_EQUAL
26 August - MEMORY_CORRUPTION (2)
26 August - SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION
11 October - SYSTEM_THREAD_NOT_HANDLED
12 October - MEMORY_MANAGEMENT
17 October - PAGE_FAULT_IN_NONPAGED_AREA
27 October - KERNEL_DATA_IMAGE_ERROR
27 October - UNMOUNTABLE_BOOT_DEVICE
(The last two didn't create a minidump for some reason)
Things done so far, to no avail:
Memory modules taken out, one by one - alas, TuffTest, MemTest, Windows Memory Diagnostic say no errors.
New psu - didn't solve errors
Updating drivers - didn't solve anything
Updating Windows - didn't solve anything
Two OS reinstallations due to crashes and Vista Repairs not working, didnt solve anything
What is very odd is this:
I did a TuffTest disk test (Seek Test and Surface Analysis) on his machine and it came up with F004 errors - Sector not found. Then I put the disk in my test machine, same errors. Then I tried it in his machine again with 1 memory module at a time, same errors. However, after testing the disk test again, putting the 2 modules back, the test was error-free!!
Also, in the Event Log, about once an hour, I get "some processor performance power features have been disabled due to a known bad firmware problem. Please contact the manufacturer." I did this last Friday, and still no answer!!
My mate and I (he works with computers as well) both think it's now a motherboard problem, but as it's intermittent, we're struggling!!
