Display ranomly dies on a new build

May 12, 2012 at 05:29:36
Specs: Windows 7, AMD Phenom II 3.4 GHz / 8 gigs RAM
My monitor (Older Acer LCD monitor) seems to randomly switch into "Input not supported" This has happened in the bios, and while in 640x480. it is a new build.
Other symptoms include the keyboard LED (Num Lock) remaining lit after I power off the PC, and being unable to toggle its on/off state after the screen goes blank; and what sounds like a BIOS Beep when I turn off the PC. Another odd thing I've noticed is that I get my Bios splash screen twice. What could be causing this?

More info about your hardware is required.

The keyboard LED is normal, just disconnect the power cord from the socket if u want it gone.

As for shutdown beep it can be disabled in win 7.

Slashscreen is normal, disable it in BIOS.

Try to swap monitor data cable.

Specs per request:

750 watt PSU

Team Xtreem Dark Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model TXD38192M1600HC9DC-D

ASUS M4A87TD/USB3 AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

HIS IceQ H567Q1GD Radeon HD 5670 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card w/ Eyefinity

AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor HDZ965FBGMBOX

OK I have it narrowed down to my video card (Pretty sure) I tested the same monitor and cable on my working machine, and it works fine (I'm using it all right now!) When I swapped the video card for the one in the new build, the same issue of randomly displaying Input Not Supported.

ALSO, in moving around the case of the new build, I discovered that one of my wires on my 24 PIN connector was loose enough that the exposed wire came up out of the pin connector. it's the red cord. Could this have fried my video card? what could this cause?
