(not sure that this is the right place for this so i apologize in advance)
I've been using my flat screen as a monitor using an hdmi cable. The tv works grand and I tested out the hdmi cable on my laptop with no issues, but I get nothing from my tower. I just booted it up one day and nothing came up on the screen. I didn't move it, unplug anything, pour liquid on it, yada yada. The only thing I can think of that may have done something was a power blink during a gnarly storm that abruptly shut it off. When I start it up it gives three ~2 second long beeps but I think it may have done that before the display went out, I'm not totally sure. I haven't tried a VGA cable but both walmart and target have weird new versions that I don't think would work with my TV and even if I did I don't have the money to drop $25 on a fancy cable.
It's a ProMagix E2010 and I'm just going to list off the specs from the sticker on the case.
Processor - Intel Core 2 Duo E6400
Video card - 256MB eVGA NVIDIA GeForce 7600 GS
Motherboard - Intel 965x motherboard
RAM - 1024MB Corsair Memory
And the original hard drive was switched out with a 1TB that I don't know anything about.
