I've built myself a pretty nice machine which has been working well for about a year, but as of yesterday I'm only able to freely operate it from a Knoppix live CD.
First, the heart of the issue:
On both cold and warm bootup attempts, the PC with load and post bios without a problem. Can enter BIOS settings no problem, can enter RAID controller settings no problem. When it comes time to load the bootloader and pop into Windows, the PC will just stay on a black screen with a blinking curser. No activity, no way to enter safe mode, no response to any input. If I attempt to boot from a CD, I can enter the preinstall environment without an issue, but for the moast part, anything I do within that PE is useless as I can still not boot after restarting, with one exception I'll note below.
I can modify my windows 7 installation and even fully install windows 7 onto my RAID0. When I install a new OS onto the primary drive(s), the PC acts normally for a few hours and I don't seem to have the same problem. Then, it'll randomly lock up once and I'm back to square one. I've run 9 passes on a memtest without issue, the video card is clearly working, the BIOS is working, the processor is clearly working and the hard drives are not the problem. I know this for two reasons- the first being that as of yesterday the primary drives are two brand new Crucial SSDs in RAID 0 which pass chkdsk, and the second is that is have another windows 7 installed on two WD caviar black drives in a second RAID 0 (which I have been using for the past year) which also do not boot when set to primary. I have a soundblaster X-fi card (it's a piece of crap but I like it better then Realtek) which I figured to just yank out of the system, to no avail. As a PC tech I usually use LIVE PE CDs on a misbehaving PC to see if the problem is indeed hardware based, and so right now I'm typing this up from a Knoppix live OS on what seems to be fully functioning hardware. Also, something odd- one of the fans in the front of the case is a 200mm red LED intake fan. It gets its power from the Mobo, and no longer lights up as of yesterday.
I was first clued in to the fact that something was wrong with the system immediately after the strom which blew down my whole dam neighborhood last week. I'm in Queens NY and we had a crippeling storm I'm sure you've heard of. When I returned home that day I found my PC totally frozen with popping sounds coming from the speakers. After a restart, there was a small HDD issue (this was on the WD caviar black RAID 0) which was fixed with a chkdsk. The system has been periodically locking up since then, but for the most part has been fully functional. The PC would always still boot into windows. Now I know as well as most of you do that as soon as some HDDs have a small problem it can just balloon into something worse, so I sent out for these two SSDs to run my OS from. This seems to have greatly exacerbated the issue, after their introduction into the system and the OS install on them, the freeze ups left me with this horrid problem. The system was able to make it past two BSODs before it would no longer boot: stop message was 0X0000004A, and they were not back to back crashes.
I removed the Soundblaster from a PCI slot on the machine and popped in a BIOS card, restarted and waited for the BIOS code during the freeze. The code came back as 00, which on an award BIOS simply means that BIOS has done its POST sucessfully and is waiting for the bootloader; big freaking help. As stated before I was able to run windows's memory test from my Windows 7 CD 9 passes through without an issue. During my TWO fresh Windows 7 installations on the new drives I loaded all most recent hardware drivers, including (what should be) the most recent RAID drivers. I can boot into the windows 7 RC with a fully responsive command prompt, and even run their startup repair tool. It is worth mentioning that a few times last night, it locked up and froze three times in that PE during attempts to repair the startup sequence. This morning it completed without an issue so I think the freezes were incidental. I've disconnected the DVD-ROM drive, some case fans and two of the 5 hard disks to see if the PSU wasn't doing the job- it seems to be fine. I'm using a few different SATA cables to connect the drives, so I switched them around and replaced the different one on the primary RAID disks. I fully reset the BIOS and had to re-enter my jumperless configuration for my RAM. Almost even replaced the CMOS battery before I thought that my system time would be all screwy if that had gone bad. It only seems to boot fine after it creates the temporary partition during an OS install, and then for a few hours after that until it decides to freeze again and bring me back to square one.

I know this is long but it's quite involved. You great techs of the internet, someone please give me some ideas I may not have tried! I thank you all in advance for any ideas, and will of course let you know of a resolution.
