Hi guys, I'm desperate for some help. My pc turns on but it doesn't boot, no power on mouse, keyboard, DVD player and card reader. I built it on 2011.

This is what happened, I tried connecting my system to my hd tv using an hdmi cable. When I turned on my pc, the only thing on the display was my wallpaper and it was flickering. Icons and task bar didn't show up. Turned it off and hook it back on to my monitor, when I hit power button, pc turned on but there was no beep, no boot, no power on mouse , keyboard, DVD player, and card reader.

Need some advice.

Hi and welcome to the forums,
I'm suspecting a problem with your video card. The first thing I would do is remove and reseat the video card. If that doesn't make a difference, and if you have onboard graphics, I would try pulling the card completely and using the onboard graphics to see if that allows the PC to boot to Windows. If neither of these approaches works you've at least eliminated the video card as the source of the problem.

Thanks for the respond compnovo. I have tried some graphics card on it and still didn't work. I disassembled my system several times. Checked if the CPU has contact with the cooling fan or if has enough thermal paste. Reseated the RAMs. Lessen the load of the pc to see if its the PSU. None of this worked.

When you say stays on, you mean fans run and thats it?
Does it act like it goes into sleep mode after failed boot?

I had a corsair PSU do that though it would boot using onboard graphics.

Unfortunitly you do not have onboard to try.

If just the MOBO LED and fans are all your getting, then you aren't getting through post. You should get a beep code, if that is the case. A single beep is fine, but when you get something else, knowing what they are is helpful, such as 1 short 2 long beeps.

Obviously your PC is dead and something on the motherboard may have been damaged when you tried HD TV with it. Maybe due to wrong signal or too high/low voltage? Does your computer/card have a TV tuner or you just connected it with an HDMI cable and said que sera, sera? I'm afraid you need to take your hardware to a GOOD service point for a thorough examination. As I said, it looks like a hardware problem.

There shouldn't be a problem connecting to a tv that I am aware of.
I currently have my main and a backup pc connected via an HDMI connection.
My backup pc had a blu-ray drive and I use it to view movies on my TV.

Try this for grins and giggles.

Completely power down.
And open your psu power switch so your pc won't come on.
Press start button to drain any stored power.

Then unplug the 20-24 pin connector and make sure you reconnect firmly.
Just a shot that a connection from the psu isn't making a proper connection.
If that fails and a possible loaner PSU fails, not sure what else to say about it.

Don't want to recommend replacing something without confidence it will bring the solution.
