Just put my first homebuilt system together and I'm not getting any video.
All parts are new, GPU is from just before Christmas but hasn't been used, all other parts apart from DVD drive which has been cannibalised from an old system have just arrived.
CPU - i5 - 750 CPU HS - Zalman CNPS10X RAM - Patriot Sector 5 G Series 4GB 2x2GB PC3-12800 Mobo - Gigabyte GA-P55A-UD3 PSU - OCZ ModXStream 600W Modular GPU - Sapphire Radeon 5770 1GB HDD - Samsung Spinpoint F3 1TB Case - Antec 300
I have tried the 5770 through the HDMI and through the DVI via a VGA cable through a DVI->VGA adapter and there was no video signal through either monitor used, tried another GPU, an ATI X1650SE, which worked earlier today with the same VGA via DVI->VGA adapter so I'm pretty sure it's not the GPU that's the problem. I've made sure everything is plugged in correctly, GPU has the 6-pin connected, Mobo has 8-pin CPU and 20+4 pin connected, when power is turned on all fans spin properly, HDD and DVD drive both turn on, GPU periodically speeds up then slows down and gets warmer, CPU gets warm, so I don't think it's a PSU or forgotten cable problem either. I've run through the checklist and I'm sure that everything's in the right place, yet the system still refuses to send video signal and there are no lights on the USB keyboard. Any help would be great

Did you install the motherboard with the standoffs provided with the case? Most of the time, the motherboard will refuse to power up if you don't.
Yeah I did I made sure to only use the nine that there were spaces for on the motherboard, and the mobo seems to be powering up, the CPU indicator lights at the top turn on with 1 and 2 green, the other two red/amber
Did you perform steps 6 - 8 in the checklist to rule out the RAM as the problem? You need to try each stick of RAM by itself in the first RAM slot. You also need to ensure you're using the correct RAM slots.
Check the bios to make sure you disabled on board video and enabled the video card - or you can plug video cable into board to see if you get video, this will also confirm board is working ok if you get video.
my bad no on board on the Gigabyte GA-P55A-UD3. I would still check the bios and make sure the video is there.
Hey everyone tried switching out the RAM modules and it's installing W7 as I type Guess I forgot that part *doh* Thanks a lot for your replies. If an admin could change this to Solved that'd be great.
You can mark it as "solved" by picking a best answer.
