(adsbygoogle = window.adsbygoogle || []).push({}); i have just bought a bunch of new parts and i assembled a computer
When i press the power button all the fans turn on and the LED's turn on but there is no signal going to the monitor. I am using standard VGA and i have tested for bad ram and i have tried removing as much as i could but still being able to boot the bios theoretically. Nothing shows up.

my parts:

500gb seagate HDD 7200 rpm

diamond radeon hd 6870 1gb 256-bit GDDR5 PCI express

cooler master extreme power plus RS-500-PCAR 500W

2x2gb DDR3 SDRAM desktop memory

asus lx 1156 intel h55 micro atx intel motherboard

intel core i5-760 2.8ghz

please help

Alright take out your graphics card and then plug your VGA up to the motherboard graphics... Then install the drivers for your graphics card and then when done re put in the Radeon and plug your VGA cable into the RADEON card not the motherboard..

The gfx card should work even without the drivers. Did you plug in the pci express power to the graphics card

i found out my pcu only has 1 6-pin connector so im going to get an adapter that will give me another one. But even when the video card is not in the computer there is no display. I also think my ram may be incompatible with my motherboard but im not sure

Wow I just re-read this and you realize that your power supply is WAAAAAAY too low of a wattage, you need around 750, my old 600 couldnt keep up with an AMD quad, 4GB of ram, and a 5770, all lower wattage than your parts.

Your right I didnt read that either.... I did not see what power supply you had... I would recommend getting at least a 700 watt..

so i definitely need a new power supply? and i notcied the ram is 1600mhz but my motherboard seems to only support 1333mhz or 1066mhz. Do i need new ram too?

It might be a smart decision to get 1333. Get corsair or kingston. Its a possibility that it would work right with your current ram, but it would be more stable if you got 1333.

When i use my computer, i get signal to my screen for a period of time but then the screen goes blank. It works fine when i take the graphics card out and use on-board. Could this be because of my PSU that its to small?
