Still getting surges/browns with UPS

I think it's just warning you that it's happened, but the UPS corrected for it.
He said Intel sensor software, so I'd assume that is happening past that. What kind of PSU are you using? Actually, I don't know what the acceptable fluctuations are for the 3.3... but the UPS is cleaning the power that comes through, so its not the outside power that is causing this problem.
Yeah 3.3 volts would be from the PSU itself. So it's either not supplying enough (most likely and the cause for random reboots and stuff) or too much (unlikely cause you'd have fried bits by now).
Install Motherboard Monitor and start it's logging. Check to see if the 3.3+ volt (or any of them) have gone off what they're supposed to. Chances are it's a faulty PSU.

my 3.3 runs at 3.42 but hasn't caused any problems yet *shrug* much as my 5 runs at 4.95, and my 12 runs at 12.17. All those are within acceptable rates, or so I've heard.
Yeah, as others have stated, it's the PSU that's causing those types of problems, but missing the mark by a whole volt is quite a lot. Is that software the soft that came with your motherboard? Try sitting at the BIOS screen and watching the voltages from there for a while. They probably won't fluctuate as much since there isn't anything going on with the machine, though.
I think you misplaced a decimal point somewhere. These variations are all less than 0.2v. The 3.3v line is over by almost 4%, which I think is a bit marginal, but it should be within tolerance.
edit: nm, I guess you were talking about the fluctuations mentioned earlier. It sounds like they're going over rather than under, or the OS shouldn't have survived to log the second reading...
Ehh... it depends if its the PSU that is at fault. If not, then buying a PSU would be kind of... wasteful. I'd try to borrow a PSU, or get one from a place with an easy-to-abuse return policy. If you still have issues, it may well be the mainboard. Which is why I asked if it was under warranty.
You could of course have really shittiy power comming into your house. You'd be surprised how bad it can be sometimes. You just never noticed it before because alot of equipment is designed to deal with very large power variations.
