I've received a dozen different Blue Screen errors while attempting to install windows 7?

Originally I had windows 7 32-bit but I installed more ram so using format d: I wiped my drive and attempted to install windows 7 64-bit. At random intervals I've received: PAGE_FAULT_IN_NONPAGED_AREA, DRIVER_IRQL_NOT_LESS_OR_EQUAL, STOP: c000021a {fatal system error}, REFERENCE_BY_POINTER, SYSTEM_SERVICE_EXCEPTION, IRQL_NOT_LESS_OR_EQUAL, TDI.SYS (STOP: 0x000000BE), STOP: 0x0000001E, CACHE_MANAGER (STOP: 0x00000034), and STOP:000000F4. All of these messages occur when I try to boot from a windows disk. I'm sure if I tried it again I'd get a completely different message. This is a brand new custom built machine I was using windows 7 32-bit for weeks and it ran perfectly. Now I can't install 7 (32 or 64) I've even tried windows xp sp 3 which led to the fatal system error. I've removed my tv tuner, wireless card, one stick of ram, and unhooked my blueray player. Any suggestions?
