Ram spikes, freezes Win7

Recently my computer has begun freezing randomly. Happens fairly quickly, without warning.
Using Rainmeter, one of the charts I have on it shows RAM usage. Whenever this happens, I notice that the RAM has spiked to 90+ percent (8 gigs, usually at about 30% max). The odd thing is, it builds relatively slowly (maybe 5% or so a second), ramping up until it hits a critical point, then stays there for a while before it actually freezes the comp, which seems to happen whenever I do anything major that would involve reading/writing to the ram (typically closing Firefox is the last thing I can do before it goes altogether).

Computer does not totally freeze, the Rainmeter graph continues to run, but the mouse/keyboard become unresponsive leaving me with no control over the computer.


Any suggestions? I'm not sure if it's entirely reasonable to figure out what exactly is happening but if anybody knows of a potential solution that doesn't involve reinstalling windows I'd be grateful.
