New built computer, cannot get monitor to detect

January 11, 2012 at 17:19:09
Specs: none yet, AMD Phenom II X6 1035
Have a pc I recently built and cannot get it to connect to the monitor, I have tried disconnecting the video card and hooking into the motherboard port with no luck. I have disconnected everything else on the pc and tried again and cannot even get to access BIOS because monitor won't communicate with the pc.

The monitor isn't the problem.

It's difficult to help when you don't list any of your hardware or what's happening. Have you ever built a PC before? Did you benchtest your hardware before installing it in the case? Do you have a decent quality power supply? Did you mount the CPU & heatsink/fan properly? Did you use thermal paste? Do you hear any beeps at startup?

MSI 760GM-E51 AMD 760 motherboard
AMD Phenom II X6 1035T monitor
2--4GB Corsair XMS3 1333mhz RAM
1TB Seagate HD
XFX Radeon HD 5570 graphics card
450W diablotek power supply that came w/ the case

Connecting monitor through VGA
No OS installed yet

This is my first build, I did not bench test the products before build(my mistake on that one should have done that), I am pretty sure I mounted the CPU and heat sink properly(did not use thermal paste). I do hear 3 beeps when I try to turn the PC on but nothing else. I have tried more then 1 monitor so pretty sure that is not my issue. I have also disconnected everything except the keyboard, monitor, 1 stick of RAM, and hooked the monitor through the VGA port on the mother board but still cannot get it to connect?

Not an expert at this so any help is appreciated.

Look up your Beep code in your manual. Or here:
Unless your heat sink has preapplied thermal compound (like stock Intel's do) then you need to apply thermal compound or you will reach thermal shut down within seconds.
Make sure you have all of your motherboard stand offs properly mounted and all screws tightened.
Try a different monitor cable.
Did you remove the graphics card before trying the onboard graphics? It might matter if you left it installed.
Does your graphics card use an auxiliary connector? Was it attached? Was the card, all cards for that matter properly and fully inserted?
Did you check all connectors? Did you double check all case connectors to the motherboard? [The first time this can take almost as long as the rest of the build to make sure they all are connected correctly]
Your beep code is your best clue here so take it seriously.

You have to be a little bit crazy to keep you from going insane.

Benchtesting is a crucial step that should NEVER be skipped.

Based on the above info, I can make the following comments:

1. Diablotek power supplies suck
2. you MUST use thermal paste between the CPU & heatsink & it MUST be applied correctly. The only time it isn't necessary is when the heatsink comes with a thermal pad pre-installed
3. AMI BIOS, 3 beeps = memory error
