So I am still trying to troubleshoot this issue for my sister. Running memtest threw up a multitude of errors for the RAM so I went through the company (OCZ) and they agreed to replace it. Finally got the replacement RAM and installed. No joy. Same problems of random crashes (no longer pixelated should point out). Ran Windows Memory Diagnostic this time and once again there are errors with the RAM. I have had faulty RAM before but never have I had a replacement stick not work. This led me to ponder if perhaps something more was going on.
Does anyone elseknow what could possible be wrong? Faulty ram bays (I have tried the RAM in both)? Faulty memory controller (not sure where this is these days but would assume it is on chip now?)? Should my next step be to replace the RAM with a totally different brand and hope?
Really scratching my head on this one and my sister is getting increasingly agitated about the lack of The Sims she is playing at the moment.
EDIT: I should mention it is a Gigabyte GA-P55-USL3 Rev 2 flash with latest BIOS
