Having problems with my new computer can anyone help?

OK I just built a new computer got everything from newegg AMD Athlon II X2 250 Regor 3.0GHz Socket AM3 65W Dual-Core Processor...CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)....Seagate Barracuda 7200.12 ST31000528AS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive..... GIGABYTE GV-N250-1GI GeForce GTS 250 1GB 256-bit GDDR3 PCI Express 2.0 x16 ...... MSI 790X-G45 AM3 AMD 790X ATX AMD Motherboard..... Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power Supply so here is all what i got my question is we keep getting crashes and blue screens. Each time its a new blue screen with a new error. If i dont have enough power could that be why its happening? I have 430watt but i dont know if a power supply could cause these problems or something else.
