Could it be Memtest86+ 4.10 that is corrupted? Reason being it locked up after running for 25 minutes. There were no patterns being written to memory, and no errors on the screen. The '+' was flashing but that's all. So I did a warm reboot, and started Memtest86+ again, and this time it did not even fully load into memory and start running. I just had an incomplete Memtest86+ screen sitting there doing nothing. Should have took a picture - sorry. Next time rebooted it ran fine. Something really weird is going on here. I'm now running my version of Memtest86+ (4.00) that I downloaded and md5sum checked myself. This is the version of Memtest86+ I originally used to check the memory in 2006 when the memory was purchased. These recent memory tests were done with the Memtest86+ from the UBCD, as I could not find the CD I burnt. Dug it out now :) Regards, Keith
