computer build help
so my problem is, im building a computer and ive gotten everything but the case. thats coming on monday, so i installed my cpu, applied arctic silver, aftermarket cpu cooler, i installed my ram and my video card. i decided while i wait for my case, i might as well test it so far to see if it works, so i hooked up all the appropriate power supply cables, cpu fan and such, mouse and keyboard and monitor and plugged in the power cable, switched on my psu, pressed the handy power button my motherboard has integrated into it and it turned on for about a half second then off again, it does this every time i try it. anything that could cause this problem? anything i can do to troubleshoot it?
could it be because i didnt put enough arctic silver? or the psu or the ram? anything?
im using an amd phenom II 940 processor with a biostar TA790GX 128M motherboard g.skill ram, evga gts 250 video card and a rosewill psu, and yes i took anti static precautions, wristband, touching an old computer that i have on unpainted metal before touching anything on the motherboard
