Cpu Issues?

[SuperLee]

Hello, i am totally new to this forum and totally noob to overclocking; however looking foward into doing it, but anywayz i just started to build one and decided to go for a good motherboard. Read some reviews and decided to go with a DFI, kinda bad choice for a noobie who dont know much about overclocking...but here's the main question....i think i got arctic silver onto the pins and maybe inside the cpu slot too since i tried to replace a new heatsink. so therefore, after window loads up, there is no display and after a few good minutes it would restart automactically. wat could be the issue?!
