I forgot to add that I don't think the problem lies within the monitor, because it worked when I hooked it up to my old computer with the VGA cable.
I think my video card is receiving power. I can see the little fan on it spinning.
Hello, so this is my first computer I am trying to put together.
I put everything together and when I powered it on, my monitor (19" Samsung widescreen LCD) just says "Check Cable Signal - Analog." This is using a Link Depot DVI-to-DVI cable that did not come with the monitor.
So I decided to try the VGA cable that came with the monitor but my computer has no VGA port, so I put a DVI-to-VGA adapter on the VGA cable and linked my computer to the monitor but it said "Check Cable Signal - Digital."
My computer has 2 DVI ports and both of them do the same thing. I've double-checked to make sure everything was properly seated in their slots.
My computer consists of:
-Intel Core 2 Duo E6600 CPU
-HIPER HPU-4B580-MS ATX12V v2.2 580W Power Supply
-GIGABYTE GA-965P-DS3 Motherboard
-Kingston HyperX 2GB (2 x 1GB) DDR2 900(PC2 7200) Memory
-EVGA 256-P2-N624-AR GeForce 7900GS 256MB Video Card
-Seagate Barracuda 7200.10 ST3320620AS 320GB SATA Hard Drive
-LITE-ON 20X DVD
