Sounds like you missed the thermal pads or they did not make contact correctly to the vram chips. If it was not artifacting prior to taking the "stock cooler apart" then something went wrong when you reassembled the cooler. The 4870's run pretty warm normally, so if even one of the thermal pads was miss aligned during reassembly it could easily case the card to artifact.

windows was freezing up every minute or two, so i shutdown my pc, took the cooler apart and cleaned it, re-assembled it and the card was artifacting. i took it apart again and put it back together same results still artifacting so i dont think its not touching anything

Are you using new thermal paste?

Most likely the card is fubar'd.

If the thermal paste is conductive, be sure it only touches the gpu core, vrm, and ram chips.
I had a 4870 artifacting, thought it was over-heating. I upgraded the cooler then put heatsinks on the vrm and ram it worked fine. There is also a small chance the card is now screwed... Good luck.
