Computer turns on for a few seconds and then turns off

HP Recommended
Hp Envy Phoenix 810 160
Microsoft Windows 10 (64-bit)

I changed out the graphics card to a newer one.

 

The computer turns on for a few seconds before turning off and repeating the process. By changing around the ram cards I have been able to prolong the time it stays on to about 20 seconds but there is no signal going to the monitor or keyboard. There is not a significant amount of dust on the fans nor wires out of place. I think it might be a power supply issue. This has happened before. Thank you for taking time to help me.

1. EDIT: Your computer: HP ENVY Phoenix 810-160 Desktop PC Product Specifications are:

 

Product number: F3D90AA
Release date: 4-Jan-2014
Country/region sold in: United States

 

What model of graphics card did you remove?

What model of graphics card did you install?

If you remove the new graphics card, and revert to the original, does your computer work?

 

Some new graphics cards simply are not compatible with older (late-late-2013) motherboards.

 

2. If you revert to the original, and the power-supply is OK, then your computer will be OK.

If you revert to the original, and the power-supply is not OK, then your computer will not be OK.

 

3. Tell us the details.

I removed the Nvidia Geforce 640 that came with the computer and put in a Nvidia 760 I believe. I can't get the graphics card out because the switch that is supposed to release it is only partially releasing it. This is an MS-7826 (Kaili) Motherboard.

The motherboard has a "locking" tab, and a lever.

It's at the end opposite from the external video ports.

Pull the lever "away" from PCI-E slot, to release the graphic adapter.

Then, pull the graphic adapter out of the slot.

I don't have the original on me, but when I took out the graphics card the problem persisted. Even if it's broken I'd like to figure out which piece of hardware has the issue so I can use the other parts to build a new one. Thank you for helping me

1. That's not good.  Your computer's specifications include:

 

Intel HD Graphics 4600 (GT2) integrated graphics

 

Integrated video not available if a graphics card or an Intel processor ending with “P” is installed.

 

  • A processor that supports graphics is required for integrated graphics to be enabled
  • Intel HD Graphics 4600 (GT2) (supported by the processor)
  • Supports DirectX 11
  • DVI-D and DVI-I output ports (both ports can be used at the same time)

So, if the "instant-off" problem occurs using that "integrated" adapter, the remaining suspects are:

  • power-supply
  • motherboard
  • processor
  • RAM

In order of increasing difficulty:

  • If you have more than one stick of RAM, remove all-but-one, and try one stick at a time.
  • It's not difficult to temporarily connect a different power-supply (don't connect the HDD nor CD/DVD).
  • It's not trivial to find a compatible processor, nor to swap it in.
  • It's a major effort to replace the motherboard.
