Multiple BSODs and Crashes, Memory Management and Page Fault

So, for a long time now, probably going on over a year, I've been wrestling with my computer. I should get a new one, and just start from zero, but I can't afford that right now, so I'm hoping that I may be able to get some help here.

Essentially, my computer crashes a lot, sometimes randomly and sometimes with noticeable patterns. It's sometimes a BSOD (usually Memory Management, sometimes Page Fault, and I got a Driver IRQL a long time ago), and sometimes it's just a flat hang with a stuttering sound repeating until I do a hard reset.

Something I've noticed lately is it crashes more often when I have flash player up for some reason or another, but especially for streaming videos. There's also been a couple of times where first firefox and/or the flash plugin will crash, then the PC will run for a bit, but if I try to bring firefox back up it will hang or BSOD. I've gotten crashes for other reasons, though.

In addition, sometimes when I start the PC up, it won't post, saying a BIOS checksum failed and that it can't detect a keyboard. That's usually solved by restarting it once or twice more.

I've had other various errors in the past, but that's the majority of it, and what's been happening recently.

The following is the steps I've taken so far:
1. Run Memtest86+, overnight and for hours at a time, no errors.
2. Run various hard drive checking utilities, no errors.
3. Run chkdsk on both hard drives, I've gotten the occasional bad sector but hasn't changed crashes afterward.
4. Reinstalled Windows, both repair and clean. I've also done sfc /scannow afterward and everything was fine.
5. Removed Daemontools, Avast (replaced with MSE), and several other bad programs.
6. Run CCleaner and various registry fixing tools. I've had registry errors but cleaning them hasn't helped.
7. Run Full virus and malware scans, both originally with Avast, then with MSE, and also Malwarebytes, no viruses.
8. Replaced the Motherboard, Graphics Card, and CPU (at various points since the problems first started, not always as an attempt to specifically fix it, but worth mentioning).
9. Updated the BIOS on the replaced motherboard, and replaced its battery.
10. Reinstalled Flash and kept it updated, just in case. No luck.
11. Similarly, I've kept all my drivers up to date, and use Windows Update regularly.

I'm at my wit's end trying to find a way to make my PC stable. Any help or insight would be appreciated.

Logs attached per the forum instruction, but that only has the last one, due to the aforementioned reinstall and cleans. If I get a new BSOD I'll update it.

just analysed the .dmp files and what really concerned me was this bit at the endof the dump file:

IMAGE_NAME: memory_corruption

this and a few other things in there indicated possible corruppted memory, if this is the case I would reccomend backing up all files IMMEDIATELY and then, just to confirm what is happening, run memtest and get back to me with results

Memtest86+ - Advanced Memory Diagnostic Tool

I've run memtest before, with no luck, but tomorrow I'll give it another shot and let you know (can't right now because it's doing another checkdsk just because I realized I hadn't in a while).

So, I ran Memtest and for the first time I actually did get an error, happened on the second pass. I imagine my next step is to test one stick at a time, right? And if I can narrow it down to only one giving errors, try a different memory slot for that one? (Though i've switched slots before, so I doubt it's a bad slot)

Whatever the case, I'll do them one at a time tomorrow. Any other steps I should take in the meantime?

EDIT: I meant to add, I also nearly always get a bluescreen when I try to come back up from hibernate; is that something that might be connected to the same issue?

I don't really know if the hibernate issue is connected, but test all your sticks of memory and see if there is one that is playing up.

So I've gotten one of the sticks through eight passes with no problems, which actually worries me a little because I still had the BOIS checksum error problem, and had to reset a few times before I could even get into memcheck in the first place. The second stick's going now, and didn't have that issue, but that doesn't mean much since it's entirely random. But I guess we'll see what happens.

you mentioned a BIOS Checksum error, here is an article about them

Heh, I've actually read that exact article. My cmos battery is fairly new, so what I've been thinking is maybe when I flashed the BIOS when I got the motherboard something went slightly wrong (I had to flash it for my CPU to be compatible). But I don't want to redo that if I don't have to, given what can go wrong and all.

So, running the RAM sticks separately, I got no errors over 8 passes on both of them. I'll have to send them through it agian, since the error with both means one or the other has to be bad. Or theoretically something on the Mobo, but that'd also show up with either one.
