First the parts. MOBO: ASRock 890FX Deluxe4 RAM: Kingston HyperX (2x2GB) 240-pin DDR3 SDRAM DDR3 1333 Memory Model KHX1333C7D3K2/4GX GPU: XFX HD=687A-ZNFC Radeon HD 6870 1GB 356-bit DDR5 PCI Express 2.1 x16 HDCP CPU: AMD Phenom II X4 955 Black Edition PSU: Seasonic x650 Gold 650W ATX12V v2.3/EPS 12V v2.91 CPU Cooler: Coolermaster V8 I'm having a boot problem. I was able to start up once and go into the BIOS no problem. I didn't change anything except the time and date. I figured it was time to install Windows 7 after that. Put in the disc, turned the system off to reboot and nothing. The case lights/fans turn on for a brief second as well as the MOBO lights and CPU cooler, then nothing. You can hear the PSU click as if it wants to power on but won't or can't. I don't have anything up to date like this setup as my other system is 6 yrs old. So swapping out parts is a no go. I tried the newer psu on the older computer and had the same results. Fans spin for a second as well as lights and then nothing. I then removed the ASRock from my new case, hooked up the psu to the cpu/mobo/gpu/no gpu and still the same result. Would it be safe to assume that the psu is bad? Or am I missing something else?
