New build, have video but displays random colors

By tim ·
Hello, I am doing my first build and am having a major issue and need help. I tried starting the system up after completely the assembly. Upon pressing the power button, all fans kicked on, hard drive started spinning and everything seemed to be working. The monitor is getting video signal, however it only shows a random assortment of colors and mush. I have restarted several times, tried to do a barebones boot(cpu,1 stick of ram, and power), & cleared the CMOS. Am I missing something or do I have a bad component. Let me give you my specs:
MOBO - Asus M4A78T-E (using onboard video)
CPU - AMD Phenom II X4 810 2.6Ghz
RAM - OCZ Platinum 4GB(2x2GB) DDR3 2000 (OCZ3P20004GK)
HD - Western Digital Caviar Black WD1001FALS 1TB
PSU - Nexus NX-8060 600W
If you have any suggestions I will gladly try them as I would much rather fix a component myself than have to RMA it and wait for the replacement. Thank you!

Check unplugging the display cable to get onscreen message as "Check signal cable". If it does, then the monitor self test passes.

Since its your newly build , try connecting any other monitor to the CPU and try connecting the monitor to other CPU. If every thing passes, remove all the cables from your CPU. Perform a power drain (Pressing and holding the power button for a minute, releasing it for about 15 seconds and again holding it for 45 seconds and releasing it). If everything holds good except from ur CPU end, check the video card.

well...

I did test the monitor already. It works just fine on my other desktop on both VGA & DVI. Unfortunately I don't have another monitor to test with to see if it just doesn't like that monitor. I did a couple of power drains last night. Same thing. Also, I am not using a video card, I am using onboard graphics.

onboard graphics

hi
worth checking in BIOS to ensure onboard graphics are enabled - have you got a spare graphics card PCI-e or PCI to test graphic output,
you may also have to select 'first graphical output device' in BIOS to suit your setup

unfortunately...

I can't get to BIOS or anything. I have not had a chance to get to the BIOS or install an OS or anything. Immediately upon power on, all it displays is the random fuzzy colors. I don't see a splash screen or anything, just fuzzy random colors. Unfortunately, I don't have a spare graphics card laying around to test if it is just the onboard graphics that is bad.

Sounds like your on-board graphic card is going...

Get another card to test it out.

hi
sounds to me like its RMA time...
if the monitor works on another machine, it works...
did you already try resetting the CMOS? use the jumpers if available
If you have no other graphics cards to check it with, the only thing I can suggest is check the PC for shorts or visible damage to the mobo, oh and double the check the cable
cheers
