so i have gotten some parts and built myself a new computer... but it doesn't work at all! basically when i turn it on, the parts all activate, the light on the motherboard comes on, indicating that it's working, and all the lights on my case indicated the DVD drive, internet, etc, come on... but nothing happens. the mouse wont light up, the keyboard doesnt light up or respond, and the monitor shows nothing... i've checked everything and im starting to think the motherboard itself is faulty. my ram is guaranteed compatible with the motherboard on corsair's website, the processor is on the motherboard's QVL, and the PSU can't be at fault (i think) because i tried booting up with very few components plugged in and got a similar result (plus it lights up). i already tried the clear RTC jumper, and booted up on some cardboard to check for shorts with the case, but nothing happens. so am i correct in the assumption that it's the motherboard and should i send it back to where i got it? (if you think its the processor then i still have to send it all back, they came in a bundle). any help appreciated.
