As per the "read this first" thread's advice, the computer has these specs:

Asus P8Z77-V LX Motherboard
Intel Ivy Bridge I7 3770K Unlocked CPU
2tb Sata Hard Drive
16gb DDR3 1333 Memory
Nvidia Geforce GTX 680 2gb GDDR5 with HDMI
24x Dual Layer Sata DVD Writer
750 Watt Branded Power Supply
Windows 7 Home PREMIUM 64bit With Disc and License

The problem:

The computer sounds normal when turned on - no beeped error message as far as I can tell, the keyboard/mouse gain power, et cetera - but the monitor displays the same "No Signal" message you'd get if you turned it on without connecting it to ANYTHING. I tried moving the mouse/using the keyboard, checking/re-inserting the cable, still didn't work. I've now tried four monitors - two using a VGA connection and two using HDMI - and I get the same result with all of them. My TV (HDMI connection) does switch to the appropriate channel when the computer is turned on, but gives no further sign there's anything connected. The computer is new (as in, it arrived today) and has had this issue from the start. I've emailed the COMPANY in question (Freshtech Solutions UK) but have yet to get a response.

Is there some basic step I've missed, or do I have a faulty component? Thanks in advance to any replies.Well whatever it turns out to be and my suspicion is the graphics card YOU should NOT try to do anything yourself. You should rely on your warranty for the resolution to this.To do otherwise may provide an excuse to void the warranty.truenorthWith all power removed try removing and re-seating the vid card...

If that produces no joy-joy i'd sugest testing the card in another PC... Quote from: patio on July 13, 2012, 09:06:12 PM

Won't this void warranty?

I don't know...did you call the Manuf. of his PC to find out ? ?
