Ok guys, I'm about ready to tear out what little hair I have left. I need help.
Here's what happened:
I was playing the Starcraft 2 beta on Windows 7 64 bit home premium, decided I had enough, quit out of the program, about this same time my cable internet connection died (that was bright house's fault) and my computer started to freeze up. Ok fine, its a beta, freezing happens. I restart. Blue screen.
Over the next few restarts I get a few blue screens including pagefile in a non-pagefile area and memory manager errors. Safe mode works off and on as I disable start-up programs and try to transfer files to my other internal hdd.
I try to fix it by limiting start-up programs, uninstalling AVG, and re-installing drivers which all had mysteriously failed including network drivers - no internet even when it starts working again. Win7 also starts saying that it may not be authentic and needs to confirm its authenticity. (it is authentic, i have legit dvds from MS) Computer not stable at all. I get everything I need backed up and decide windows 7 needs to be re-installed.
I do a quick format in NTFS with my external docking bay attached to laptop, try to re-install windows and get BOOTMGR not found errors every time. I can boot off of dvd but if I don't hit a button soon enough the BOOTMGR not found error pops up and I have to ctrl alt del and try again.
I run memory check, no problems, i run bootrec /fixboot and that doesn't do anything. Same error. I try installing win7 again and it gets to expanding windows files and doesn't even get to 1% and says files not found. Oh crap.
Ok, I pull hdd, do a full reformat overnight, clear cmos, reset everything back to default in my mobo except I turn back on usb devices. try installing again and it gets to 2% expanding and same error. (error code 0x80070570)
Nuts. I try bootrec /fixboot and bootrec /fixmbr (in that order, is that right?) Still get BOOTMGR not found.
Now the win7 installation menu takes literally minutes to even appear when I access it where it used to be instant. Still will not install. I tried to copy files to USB to do a bootable USB but was never able to get it to work.

It was running fine since I built it in October 2009, completely stable with a 3.6ghz overclock temps in the high 30's up to 43ish at idle and no more than mid 70's during stress tests.
I spent a bit of money on this and now its an oversized and loud paperweight. I've done all kinds of google searches, tried almost everything. I'm not a noob I'm usually the one fixing computers but this has me stumped. Please help. If you need more info, please ask!
Mushkin is a good company and I hear their RAM is very good. I'm using G.SKILL myself, which is also very reliable RAM. My board only supports DDR2. You probably already know this, but just make sure the RAM is compatible with your mobo.
Memtest should be able to tell you which DIMM stick it was. At least from what I remember, but it's been a long time since I used Memtest. Can you run Memtest on each stick individually? At least that way you could narrow it down and not have to replace them all.
