Has anyone really found a bad memory module in their system, or is it time for a new laptop?

The saga continues. Two new updates. First, yesterday while the laptop was idling, I received a BSOD I've never seen before: driver_overran_stack_buffer. Hmm. According to Microsoft: "A driver overran a stack-based buffer (or local variable) in a way that would have overwritten the function's return address and jumped back to an arbitrary address when the function returned. This is the classic "buffer overrun" hacking attack. The system has been brought down to prevent a malicious user from gaining complete control of it." Double hmm. Full virus scan found nothing. Of course, all of the other references indicate bad drivers, which I have had a terrible time with Microsoft replacing drivers. Over the weekend, I'll run a deep scan booting off a USB drive. We'll see if anything else pops up. ---------------- Second weird issue - RAM. Since I've had this laptop, I have had 64GB in it. I purchased two Crucial SO-DIMMs. When I pull up the BIOS, it sees 64GB. When I check task manager, it says 64GB. But the label on each module says 16GB. I sent the picture to Crucial. They confirmed 16GB. Suggested maybe a labeling issue with the vendor. Dude, it's YOUR label on the SO-DIMM :). Support did not understand. I'm in touch with Micron to determine the true density of the chips which I'm pretty sure are sized for 32GB. The entire point of the RAM exercise is if I replace the RAM, I need to make sure I order the correct part. I got these from Amazon which is totally useless from a customer support perspective. I'll go to NewEgg next time.

As an aside, does anyone have a recommendation for a good virus/malware (I guess they are the same these days). I'm specifically looking for something I can boot off a USB that is an excellent scanner.

I may have in my desktop. I'd been getting crashes that my crash analysis tool suggested were probably memory related over the last year and which got markedly worse recently, memtest86 ran clear overnight. Friday morning I down-clocked my ram from DDR3-2400 to DDR3-1600 and have been crash free over the weekend; long enough to suggest the issue is solved. That said I'm sure sure it's an inherent memory problem; my CPU is watercooled so there's not a ton of airflow around the ram; and since early this year I've been using an aircooled GPU again (and more recently a hotter/faster one). My ram is hot to the touch, so it's possible I'm just seeing an overheating issue that memtest86 by leaving the rest of the system at idle didn't trigger. I'm probably going to order a ram cooler later this week and see if that lets me restore to full speed operation.

Well after suffering a weekend and a few days of BSODs, I have new ram installed. If it hasn't crashed in 8 hours, Crucial is getting their ram back.
