NO VIDEO OUTPUT :( help~~

Hey forum! i just built a new rig. This is my 3rd build. using 955BE, 970FX mobo, OCZ reaper 1333 ram 8gb, Rosewill 600W power supply, and a PNY gtx 465.

I turn the computer on, the LED, and all disks are spinning. I just dont get any video out put.At first i thought it might be the video card but i switched the 465 with a 5570 and still no video.

Something is wrong. ram? CPU? mobo? oh gawd what should i do from this point to solve this problem?

there are no beeps of any kind. :( SOOOO SAD please help


EDIT okay now i swapped almost everything but the PSU and the Mobo from confirmed working parts....so i have a faulty MOBO?
 
Monitor? That would be my first guess.

Check connections? Have a spare monitor to test?

If it were the motherboard that was faulty, I would think it would do more than just nothing and show nothing.

Anything concerning video output I would immediately assume video card or monitor.
 
Sure you have all the power slots done on the mainboard. Both the 24pin as well as the 4/8 socket?

No on-board video, is there? (been burned by that before)

Pull out all but one RAM stick. Remove the HDD. Reset BIOS. See if that works. If not, I'd try resetting the CPU, just to make sure it might not be wonky.

Check the pins on the video cable - both ends.
 
Monitor: i am using my one of my double screens of another rig. no problems there.

About the on board graphics...uhmm i dont see one lol...

There is however....an LED message on the Mobo it says FF

this LED is called the debug LED: POST:LED

the message "FF" means: power on and first initialize CPU

uhmm what does this mean?
 
I am not 100% sure what "FF" means but I know my mobo displays the same always, so it must be a good thing. Fully functional maybe?

I dunno what your issue is. Disconnect everything non essential, and just try stuff. Seems like something I could debug within 10 mins if I was actually there to mess with it.... Shouldnt be difficult to figure out why no video is displayed.
 
i know many of you mentioned the 24 pin socket and the 4/7 socket?

i see the atx 24-pin power connector and a ATX 12V connector with 8 little blocks imilar to the 24 pin...that must be what we are talking about rtight?
 
okat update. I just took everything apart and out of the case. re attached the cpu heat sink, connected the 24 pin and atx 12V connector to mobo, connected 1 ram and 1 gpu to the mobo. turned it on. same thing...just an FF and no video output.
 
Youre gonna have to use your mobo manual to figure out what FF means. I read it is somewhat different depending on manufacturer. With that said, it most likely means everything is fine and that it completed post checks and bootup suggesting everything is fine with the mobo. For my abit motherboard, pretty sure it means "fully functional."

Do you have another computer to test stuff on? Plug the monitor into that computer. Then test the video card into that computer as well.
 
I have an EVGA 780i mobo, and FF means the POST is fine (successful boot). However, I do get this issue where the mobo says "FF" and I hear a long beep but there is nothing on the screen. Otherwise the harddrive sounds like its booting, and the LED activity light flashes as it it were OK. The way I fix this is by taking the video card out, and then pushing it back in really hard. I usually have to do this 5 or 6 times (or more) before it boots up OK. Maybe its a similar issue.
 
thank for your feedback. I just relocated all parts on to another amd mobo and it worked. So it's either my ram or the mobo.

damn it....

oh and for the mobo that's in question. i removed the black plastic bracket surrounding the CPU. does that someone not interfere how the mobo functions? because my current cpu heat sink requires to remove it and put on it's own.

here's a picture a mobo
 
Uhhh, that black plastic bracket is for heatsink mounting..... You definitely need that. How do you have the heatsink on the cpu if you removed that?
 
the sink i got came with it's own mounting bracket so i took the oem version off. it doesn't matter cause i but it back and it still didn't work.

I have confirmed all the parts are working parts on another rig, except for the mobo. When i put other cpu and gpu on this mobo it doesn't work. but when i put all the parts from the "mobo in question" to another mother board everything works fine. i guess i can safely assume that the mobo is broken? but the mobo displays FF which mean Fully functional? some people say i might have pluged the ram properly...i did. i check like 2000 times. I checked the 24 pin power and the the 4/8 pin cpu power, i checked the GPU PCI-E, I checked the cpu too switching out for another cpu, another heat sink. jesus i triple checked everything. i can safely say that the when i mount everything on this mobo, no video out put. when i mount everything on another mobo, everything works. but mobo displays it's functional;...What the F**** this is triving me crazy.

I think you pretty much answered your own question. If all components work when moved to a diff mobo, then it has to be the mobo. Weird though that it still displays FF.
 
i purchased this mobo from someone on Overclocker Network. OCN. He didn't tell me the mobo is already out of it's warranty period and MSI charge $35 and shipping to RMA each board.

I think it's fare of me to ask for either a refund on the board or $35 for the RMA since the mobo never worked when I received it.
 
Same problem here, but a little different. My friend is building a new pc, but he is using my old q9450, ram, and biostar motherboard. everthing else is brand new. The thing is that we can't get video to show up. Everything is turned on and spinning, but now video output. This motherboard was working perfectly a couple of weeks ago in my rig. What could it be?
