I had the same problem after upgrading from 2x 1Gb to 2x 2Gb to make Gb. apparently the RAMs sold to me weren't knew and I was not aware. freezing and restarting for about 5 times in 24 hours I carefully removed the RAMs, took my body spray (in place of methylated spirit or any ethanol) and soft toothbrush. I gently 'washed' the RAMs with it and placed them back about 10mins later More than a week and no freeze again!
