Laptop - Possible memory issue?

[NeverWinter]

Recently changed from Vista x86 to Ultimate 64, now i'm getting random BSOD.

Laptop is M1530 with 4gig Ram.

Ran memtest on each stick seperately with no errors, as soon as memtest starts (10% through first test) it closes down and reboots laptop. Any ideas?

Yeah, seperately and in either slot - No errors
Together, it crashes. I switched slots to see if that made a difference and it didn't/

Any ideas or should I just get in touch will Dells tech?
