Problem description: My computer boots but there is no display. Nothing was giving me any indication of a problem brewing. I turned my computer off normally last night and this morning it boots, but there is no display. Attempted fixes: -Reseated the memory. -Reseated the GPU. -Cleared the CMOS. -Checked multiple displays/display configurations. My GPU is connected to my monitor (DVI) and to my TV (HDMI). Neither display is receiving a signal, in fact my TV says "No Signal" when it normally would be displaying my desktop. There is no display when the GPU is removed and my monitor is connected to my motherboard (DVI). Recent changes: I built this computer 4 years ago, on this very weekend. The only changes I've made since were In the past 30 days - I added a new HDD and replaced a case fan. My old HDD was approaching eight years old so I put a new one in and copied data from old to new. The old HDD is still in my computer. My OS is installed on a SSD that was new four years ago. I think it's worth noting that while I've been troubleshooting this morning, sometimes when I turn my computer off I have to hold the power button and other times simply pressing the power button will turn it off. It seems like sometimes it's getting to the operating system (press and hold power button for shutdown) and sometimes it's not getting to the OS (only press the power button for shutdown). -- Operating system: Windows 7 64-bit System specs: Motherboard: MSI z77a-gd55 Motherboard GPU: MSI GTX 660-TI Memory: G.Skill Ripjaw 8 GB (2x 4GB) CPU: i5 3570K SSD: Corsair Force Series GS 2.5" 360GB SATA III Internal Solid State Drive (SSD) CSSD-F360GBGS-BK Old HDD: Seagate BarraCuda 7200.12 ST31000528AS 1TB 7200 RPM New HDD WD Black 2TB Performance Desktop Hard Disk Drive - 7200 RPM PSU: CORSAIR HX Series HX750 750W ATX12V 2.3 / EPS12V Case: Antec 900 Location: USA I have Googled and read the FAQ: Yes

I'd start by visually inspect the motherboard for anything obvious like a blown cap or scorching. You don't happen to have another PSU around to try? The fact you aren't getting video from the onboard even with the GPU removed is worrying. Since you were working in the case recently it might also be worth taking the motherboard out of the case and seeing if it will boot normally when sitting on a non-conductive surface. If a screw or other debris got in there while you were swapping HDDs you might be getting a short from the case.

The fact you aren't getting video from the onboard even with the GPU removed is worrying. I don't have any other PC components available to test. Last summer I looked at my like of old parts and then recycled them.  My motherboard looks fine - no scorching or damage I can observe. I'll see about removing the board and booting outside the box, but I'm not expecting to get any better results from that. I was very careful when I was working in it. I cleaned my work surface before opening the case and all the work I did was at the front of the case sliding in the new HDD and replacing a fan on the front of the case. The only work I did near the motherboard was plugging in my HDD and even then it was a clear shot to that connection. Thanks for the suggestions.

I was fiddling around with some stuff tonight and decided to give this thing one last power on and my TV got signal from the computer. I can't detect my monitor though. I think the problem is with my DVI cable and/or my monitor. I will be borrowing a DVI Cable and a monitor tomorrow to test this hunch. This is a big relief, potentially! I was not looking forward to dropping money on a new build.

Cool - hopefully it is something as simple as a cable. It should have occurred to me to suggest another cable, too.

I think it's the monitor now. My wife's laptop has a VGA out so I connected it to the monitor with a VGA to DVI cable and it can't detect the monitor. I've been using this monitor hard since August 2009, I think I've got my money's worth out of it. Now it's time to shop for a monitor... hopefully this is less stressful than a comp build! I appreciate your help regardless. It's not like you're getting paid to help the people that post on these forums!
