Occasionally, my screen becomes 'pixelated' in random areas (the image gets distorted as if it was magnified and then pixelated). My Shockwave Flash started crashes constantly a lot under Google Chrome. zip files, after uncompressing them, I sometimes get CRC errors and checksum problems. I installed it and started having problems again: I kept using SL for a few months without any problems (did't bootcamp this time) and then OS X Lion came out. I formatted the whole system and reinstalled Snow Leopard, put back the 8GB RAM and ran the mem test again, and it passed 100% this time. I figured my RAM was faulty, so I switched back to my old 2GB memory that came with the mac, but I got the same error in the mem test. I tried repairing permissions but it seemed to be beyond repair. The Windows partition worked fine, though. One day, out of nowhere, I got a kernel panic the OS X partition stopped working. It came with SL and I immediately installed BootCamp and upgraded it's memory to two 4GB, low latency Corsair. It's a mid 2010 model with 2.4Ghz and 2GB RAM.
