Is my iMac RAM incompatible?

I installed new RAM for my 2007-era iMac last week, and for a few days everything went swimmingly. Then the loud beeping started...
I previously had two 1GB RAM chips in the memory slots, and I bought two 2GB chips. So I doubled my RAM from 2GB to 4GB. Easy as pie to switch out, and when I booted up with the new RAM, it started as normal and showed that my RAM had indeed doubled to 4GB. Multitasking was indeed snappier and performance was much better.
That lasted a few days, and then suddenly, this morning, it stopped being good. Firefox froze up, and then every other program, and even Force Quit didn't work. So I rebooted and got the loud beeps, which (I already checked this out) means that the RAM is bad or simply not working for some reason. It will boot up, but freezes after a short time.
I checked the Apple website for the correct type of RAM I needed to upgrade, and when I bought it, the chips had all the specifications I needed: (PC-2 SDRAM 667Mhz, etc.) They were from a brand I haven't heard of before, and the cheapest option, but I didn't think this would be a problem. Is there bad RAM out there?
The bigger question is: why would the RAM suddenly "go bad"? I can understand if the RAM chips I bought were the wrong ones, incompatible with the iMac, but for two full days the computer worked fine. Better than fine. The only thing I can think of (and I can't actually check because I'm at work) is that I was downloading a few large files overnight and my harddrive might be close to full...could this be related? (BTW, it's obviously not a young computer, and has seen almost daily use for the past for almost five years, so it may in its twilight years. That is, about to die, and this could be a symptom.)
Should I just admit defeat and put those 1GB chips back in?
Any advice would be greatly appreciated.
