I boot up my computer and I get no beep, no USB working (no lights on keyboard / mouse), and no video. Would a faulty video card be the issue (used to have video crashes, but sound would mess up too) or is it just my motherboard is broken? how can i verify for sure?
 
test out some different cards with it, if the cards dont work try them in another system to see, if they work in another system its the mobo, if the cards dont work its the cards i had a similar issue were my mobo doesnt like the 8800GT kinda sucked
 
do you have access to another sysem to test your parts? could be motherboard or maybe somthing else.what psu are you using?
 
I'm using a OCZ GameXStream 600W PSU, I just booted it up with the card unplugged and i got the proper beep noise, along with the lights on the mouse and keyboard turning on. right now im starting to think that it is probably infact the video card. i don't got another pc i could use to test it out, thats't he only problem. Would the video card cause the computer to not post beep and not allow the mouse / keyboard to turn on? (they only briefly turn on when the card is plugged in... like less than a second)
 
If it's drawing too much power. Might even be a bad power supply. Hard to tell without being able to test the parts in another system.
 
hmm well i unplugged everything cept the mobo/cpu/hardrive and it turns on, but im wondering if the video card is the problem. I'm trying to get my hands on some random card and test it out. i want to see if it boots up with a different videocard this would confirm that its the videocard. I figure i should have enough power since its not tooo many components i have running
 
like i posted earlier your graphics card may not be bad but just incompatible with your mobo thats what my issue was the 8800 works fine in other systems and the mobo is working fine right now.
 
Could you post a full list of your system specs? We could probably help you out better from there.
 
If there is no POST beep, I would lean towards your CPU or motherboard being the guilty party. If it was RAM or GPU you would hear a series of beeps.
