BSOD on Toshiba laptop with 8 Gb but not with 4 Gb
Hi everyone,
I have a Toshiba laptop L850-138 with Win 7 Home Premium SP1 64 bits.
Around 6 months ago I replaced the original Samsung memory for a 2x 4Gb Corsair kit with same specs.
No problems until this last month when I'm getting several random BSODs, 99% caused by ntoskrnl.exe.
When I get a BSOD I'm unable to boot again until I take off one RAM module. With 4GB works fine.
But sometimes I put again both modules and runs stable for several days... until I get a BSOD again.
I have changed of place both modules, cleaning contacts, etc.
I have updated BIOS, drivers, programs. I have run SFC, Windows Memory Diagnostic, etc.
I have uninstalled Avira and replaced by MSE. I have scanned with MBAM, SuperAntispyware, anti-rootkits, etc.
I have run memtest86+ (not much passes but no errors found).
The only thing I have not tried yet is reinstalling the system but I would like to find the problem before.
Any idea?
Thanking in advance.
