Hello. This is my first post, so please have mercy on the newbie. 
I've been getting frequent (several times a day), intermittent BSODs with the following error numbers:
0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF80003222FB2, 0xFFFFF880030F8938, 0xFFFFF880030F8190)
...and no associated file name or error text (such as THIS_IS_YOUR_ERROR_TEXT).
I have recently scanned my RAM, and it had no errors. I've been using my hard drive for a long time with no errors until I installed Windows 7. I checked it for bad sectors about 6 months ago, and checked its SMART status days ago. My motherboard is new, and I just recently (after installing the new MB) installed Windows 7 on my hard drive, loaded drivers from the vendors' websites, got all Windows updates--security, plus a few others, including services packs, installed the various programs I tend to use, and installed Steam and my other games. I started getting the errors/BSODs shortly after installing Windows, and before all the updates had been completed. I've been trying different solutions suggested on the Web, and upon *thinking* I'd solved the problem each time, I'd install more software, and eventually get another BSOD. Each time, except from the times I've used verifier.exe to check drivers, the error code has been the same. The times I've used verifier.exe, the error code has been 0xC9.
I've used BlueScreenView to look at the errors, and found that when verifier is not used, the two suspect files are cng.sys and nvhda64.sys. When I've used verifier, the suspect files are nmserial.sys and ntoskrnl.sys--which makes me think that the verifier has been finding mostly non-problematic drivers and crashing on them, rather than finding the cause of the 0x7E error. The nmserial.sys file is for my MosChip PCI parallel/serial port card, which I use for my old parallel laser printer. (That thing is nearly indestructible... )
I'm using a custom-built gaming PC with the following specs:
OS: Windows 7 Ultimate 64-bit
CPU: Intel Core 2 Duo E6550
Motherboard: Biostar P43-A7
RAM: 8GB DDR2 800MHz
Video Card: Zotac GeForce 560 Ti
Sound: On-board Realtek HD Audio
Hard Drives:
500GB - Ubuntu Linux 11.04 with GRUB2 boot loader (primary)
750GB - Windows 7
1TB - PERSONAL (my important data)
1TB - PERSONAL2 (backup of PERSONAL)
Keyboard: Microsoft Comfort Curve 1.0 (with software from Windows Update)
Mouse: Logitech G9x (with software from Logitech)
It's worth noting that the video card, motherboard, and 4GB of the RAM are new.
I have a lot of experience with computer repair, but I've rarely ever come across something this stubborn, so I'd greatly appreciate your help! I'm also pretty new to Windows 7.
Thanks!

P.S. The problem happens most commonly when I come back to the PC after several hours of it sleeping, wake it with the keyboard, or mouse, then try to make it do something. It's BSOD'd after checking a box on the Assassin's Creed: Brotherhood download manager (but before clicking anything else), pausing Defraggler and telling it to resume (one after the other, to get it moving again), and from doing several other tasks that I don't remember right now. It also happens at random times when the PC hasn't been sleeping. Also, the whole PC slows to a crawl whenever I'm trying to do any kind of file transfers to/from the HD, and using a web browser or anything else at the same time. I'm using Firefox 4. In Linux, these problems don't seem to exist. Perfmon tells me that my PC has a lot of interrupts/sec., so I'm wondering if that's part of the problem. I've set the power management in Windows so that it doesn't turn off the HDs, but it seems to be doing it anyway.
