@ross06187 Thanks for your feed back, I'll give it a try

im running windows 7 64bit btw and have tried clearing cmos

lol

I'm currently building a pc for my gf, the system spec is as follows: intel 4670k cpu asus z87i pro itx mb kingston hyper x beast 8gb ram asus direct cuii amd 7850 gpu samsung evo 120gb ssd 1tb wd blue hdd corsair cs650m psu corsair h100i wc The system will boot up fine with on board integrated graphics every time through the io using a hdmi connection on a 32"inch tv. As soon as the graphics card is fitted to the motherboard and the connection is made from the graphics card to the tv I run into problems. The system will boot up fine occasionally normally when left for a long period of time using the graphics card?? which i find strange because it doesn't always boot. On start up the motherboard does post checks indicated on the led's on the motherboard. when the system boots fine all the checks go from red to green as they should, but the system doesn't always boot as normal. sometimes I get a red light on the last led check and the system refuses to post? when this happens I get the asus splash logo page butt hitting f2 and delete doesn't allow me to enter bios. After the bios screen disappears the screen goes blank and stays blank, the motherboard red led stays on. i thought this might be a bios problem as i checked post originally through integrated graphics, so i disconnected the graphics card and went into bios, i found advanced setting and changed auto detect to check pcie first on boot and saved setting and reconnected graphics card. still same problem. i re-steated gpu a few times to make sure i hadn't made a fitting mistake and still no joy. i thought maybe the graphics card had died on delivery, the green connection light lights up on the graphics card and the fans spin up so the cooler was working but i decided the card might be dead. we returned the graphics card and purchased another from a different store and still the same problem?? i wondered if my psu wasn't supplying sufficient power to the system due to connection error or a loose connector? so i reconnected all power cables and made sure the 24 pin and 8 pin were connected and seated correctly. still same problem splash page no start up. i know there isn't a problem with the cpu as there were no bent pins on socket and the system stated the cpu had installed correctly and had been recognised and the ram is detected and working fine as is ssd and hdd. All drivers are up to date aswell, only the bios and bios utilities haven't been driver updated because i don't want to risk bricking the system. Hears were it gets really strange i took the pc to my house and tried trouble shooting from my tv and it worked straight away on my 32"inch tv and worked on my tv downstairs?? surely the monitor shouldn't stop the motherboard boot up? both tvs at my house are same spec hdmi tvs as my girlfriends and when i try my gfs tv at her house it refuses to post. Tried using upstairs tv in her house so a different 1 from the original we tried on and same no boot again :(, i fiddled with her tv settings to see if there was a comparability issue on the one upstars and changed setting to auto scale on her tv. This made the pc start up as normal?? i though i had resolved the issue but now sometimes it works on that tv and other times i still get no post on it and the red light remains on. sorry for the long chat but though outline the trouble shooting id already tried thanks to all responses please help me if you can its driving me crazy lol

Sorted the problem now :) cleared CMOS as you suggested and is working great!! thanks :)

i'm setting a new build up on a maximus v formula z77 board, i installed my ram, cpu cooler and hard drive ect and the system posted on intel integrated graphic. i bought a gigabyte 7970 oc windforce ed and the motherboard flagged a b7 error code up. in my manual its a nvram reset fault. Does anyone have any idea as to how i can sort the problem out. New to system building so any advice would be great, dont think ive installed the graphics card incorrectly fans spin lol :) thanks
