Strange boot issues

[Buildncastles]

Okay, I've been having some interesting boot issues with my current Windows 7 machine. If I restart my machine it can boot up fine. If I turn the machine off for a certain amount of time (4+ hours) it has issues booting up again. I get bsods like crazy claiming that it's the memory.

When this happens (turning on the computer after 4+ hours) I'll run Memtest86+ for around 2-3 hours. There will be no errors. I will then restart and boot the machine up and BAM windows will load with no issues.

It's as if my memory needs to be "warmed up" and it can't boot from a cold boot. Does anyone have any idea what the issue could be? Is it simply the memory?

from the sound of it you could be dead on, but to verify this, is your computer in an abnormally cold room such as a basement?

No, it's not in a cold room. Normal room temperature in my living room.

Do you know of anything that you did (software or hardware) that could have caused this to happen,

EG: installing old ram, possibly bought from a friend, months back.
or installing a program/editing BIOS to make it go faster.

Those things usually can cause unrelated errors, or in this case, possibly directly related.

EDIT:

I have heard of a lot of memory problems with Windows 7, an all cases seem slightly different, this could just be a new strain. But we should chalk it up as that an leave it, lets try to get to the bottom for future problems.

I've had many previous issues with the RAM I have in the machine. I had to adjust the timings on it to 8-8-8-21 because it was "auto" setting the wrong ones. I also have it set to 2t command rate, would this cause the "slowness" of the boot or the need to "warm up"?

I know I should probably RMA the RAM but ever since I've adjusted the timings and such the system has worked well. And when I run Memtest86+ I never receive any errors so it's kinda tough to blame it all on the RAM.

Try popping in your Windows installation disc, going to the command prompt (if you get automatic recovery, hit cancel, and then click Advanced), and type fixboot. See if that works for you.

Or if that doesn't do it you could always just try the actual boot-up recovery anyways, I mean it is a bit time demanding and i'll be the first to admit It sometimes doesn't work, but it can't hurt if windows identified the problem itself (which to me always seems surprising, my PC has no clue its turning off)
