I recently decided to upgrade the memory on my 8440P EliteBook. After reading through required RAM specs, I bought one of these: http://www.ebuyer.com/737970-kingston-4gb-1333mhz-204-pin-cl9-ddr3-sodimm-non-ecc-unbuffered-1-5v-me...
Once the new RAM is installed in the expansion slot, Windows fails to boot and just hangs at the "Starting Windows" screen. I then attempted a memory test using the BIOS system diagnostic tool, but the laptop either hangs at around 35% (I left it there for almost two hours), restarts, or shuts down altogether. I thought I'd give the system repair tool a try, but that also just caused the laptop to restart. Interestingly enough, when I check the "System Information" tab in system diagnostics, both RAM sticks are detected with all information present and correct.
I contacted eBuyer, they sent a replacement out, but I'm having the same problem again. So, I thought I'd try installing the new RAM in the internal slot instead (under the keyboard), but now I get a BSOD during the "Starting Windows" screen, giving me the error code, "IRQL_NOT_LESS_OR_EQUAL".
I've been reading up on a few tech forums. One of them suggested running something called "Memtest" on startup via CD, which I did try, but the laptop just restarts itself during the first pass of the memory test (and obviously just loops over and over until I remove the CD).
I'm beginning to lose all hope! Any help/tips/suggestions would greatly appreciated.

See this related post. You have to use very specific memory in that model or it won't work.

Many thanks for your reply. I have just read through the thread you linked to. Am I right in saying this is the memory you recommend for this laptop: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231342
