HTPC HTPC kaput

So I've just opened the case up, screwed a new 840 onto the case and closed it back up.
Note, the SSD is not connected at all.

The PC then decided that the TV it is attached to is no longer a suitable device for audio
It's also not capable of outputting at 1080P (like it was this morning) instead outputting at the wonderous 1024x768.
It was recognised as a "LG-TV1" and now is a generic plug and play monitor.

So, I've checked the connections, tested with my laptop (definately not the TV/cable), reinstalled the Nvidia drivers, and I've just this second re-seated the graphics card (just to be sure).

Now it doesn't boot.
Fans spin up, fans stop. Fans spin up, fans stop. Repeat.
Thoughts? I'm suspecting the power supply myself, although entirely why it would throw a fit because I opened the case is beyond me.

The wife is home in 2 hours. I'm open to suggestions

 

Hmm, a couple of suggestions from the top of my head:

Reseat the ram
Reset the BIOS
Swap out the PSU

Try those and go from there

 

just ignore it, let her turn it on, to find it doesn't work, then blame her for breaking it :wink:

 

This sounds like wrong or no EDID. NVIDIA is doing exactly this when monitor provides no or invalid EDID, it defaults to 1024x768 no-audio (unlike Intel and AMD, which default to not recognizing the connected device at all).

Is the 4-pin CPU power connector connected ?

 

It most certainly is.

 

Great advice. My HTPC has just gone kaput too. I think my SSD has died. I'll blame the wife and get her to buy a new one

 

I've had similar things happen to me, have you left the usb key or sd card or other removal storage device connected?
I once lost a lot of hours to that as the sd card was behind the flap in my case so I didn't see it. I pretty much stripped the whole thing.

 

Update, pulled the 560Ti and the dvd drive out late last night and it doesn't do the fan stop/start thing.
I'm pinching a cable from work to go from the motherboard DVI to the TV to see if it is actually booting in that configuration.

Edit: no removable storage attached either

 

So pulled everything, put it all back in 1 piece at a time and...........it works.

I'm confused....

 

In that case it must have been a loose connection somewhere, maybe you had inadvertently knocked something when opening/closing the case up?

 

Could also be an intermittent fault.

I have a problem with my SSD. Over the last few months it stopped working completely. Then restarted again. I had to reload windows again and everything seemed fine for a month until
It happened again for good.

 

Most likely I think.....
Did track down the no sound fault to the HDMI port on my TV though.

Which is annoying ¬¬
