One year later, I still have problems with the 975X PUE

Question

A year ago, I bought the 975X PUE board and turned out to be one of the biggest mistakes I've ever made when purchasing something computer-related.
To start with, the board didn't recognize the OCZ memory that I had bought, so I had to change it for some gSkill memory.  That, however, involved a trip to Argentina since at the time it was very hard to get DDR2 memory @ 800 Mhz here in Uruguay.  I had also complained about how the temperature monitor was unreliable and problems booting the computer.
I still have those problems, but I learned to live with it since no major problems arised.  Sure, I'd have to boot three to six times just to get it running, but hey, no big deal.
Later, I decided to go for RAID1 and surprisingly, it worked so I had no new complaints.
However, lately something new has been happening.  The computer seems to reboot randomly and without warning.  This had happened before when lightning struck nearby (I blamed it on electro magnetic something) but now it happens all the time and I can't find a solution.  I leave the computer on during the night and in the mornings, I come to find that it has rebooted when I was sleeping.
Here's what I have:
MSI 975X PUE (7.1083006)
INTEL E6600
GSKILL 4 GB DDR2 800 Mhz RAM
WD 320 GB 7200 RPM
2x WD 500 GB 7200 RPM (RAID1)
NVIDIA 8800 GTS
Windows Vista 32 bit
PSU Biswal 780W 30A +12V
I've looked over the latest firmware thread that used to be a sticky on here and noticed that everything else seems to be beta.  MSI never released something better for this board?  Here's that thread: https://forum-en.msi.com/index.php?topic=99818.0
The only thing that I could think of for these random reboots is that maybe the unreliable temperature sensors fool the computer and make it seem like the CPU is a lot hotter than it actually is.  I've fired up Everest and right now, with only Firefox and a couple of IM clients running, CPUs are at 50 and 54 degrees celcius.  Taking into account that the case is open and I'm in an air conditioned room set to 24 degrees celcius and that there's a mini Typhoon on top of the E6600 as well as a couple of fans in the case, these CPU temperatures are nearly impossible.
What's going on with this?  Can anyone help me out?

Ok, lets say my PSU is degraded. That solves my spontaneous rebooting issue.  How about everything else?
I still have to boot my PC 3-6 times to get it to start.  Temperature monitor still sucks as well.
Is 7.1 the latest official firmware for this high-priced mobo?
Daiver the biswall brand is a very cheap one, I think you should buy a trusted PSU. In Argentina you can find many brands, like Topower and Power Cooler, that are good PSUs and at a fair price.
The latest bios for this mother is 7.7, but some users find it not so good as 7.6. I use 7.6 and works perfect.
