Problems

I have put together an I7/930 on a EVGA SLI 3X Mobo. (non-clisified) w/ a EVGA 470 Graphics Card. OS is Win 7 64 bit. System booted fine. Bios set up OK. no overclocking. Downloaded up-dates (not all Up-dates would load through windows) had to load graphics from divice manager, did not take first time. Pulled Card and re-seated it. Re loaded up-dates from divice manager It worked fine for a while. Enternet explorer quit working could not load, minuts later screen turned pink system froze up. I shut it all down and restarted screen came up pink again faded and froze up again. I shut it down and have not tried again. Where do I start to trouble shoot this problem???
