Can you give us some info on the case and PSU that you installed and the motherboard?

I would say one thing is the power to the motherboard can be either 20 pin or 24 pin so make sure that is right.

Also, there is a set of wires that go to the motherboard from the front panel to tell the computer to start/restart/and leds... make sure these all match on the motherboard.

The Case is a Thermaltake Element G and the PSU is a Corsair HX850W NON Modular, the power to the mobo is ok a 24 pin just checked, also i disconnected all the front panel cables to make sure it wasnt an error with them. turned on manually and same error appears

how did you take out mobo/components? did you take precautions against ESD?

another thing might be standoffs in the new case? maybe grounding out?

do you have a way to test the new PSU? it might be faulty as well.

 

[Dan011093]

yes i did it with a lot of caution. how can i test the new psu?

Hello Dan, There are some very talented people on this forum that would love to help solve your P.C issuses but you must help us first start by filling in your sys specs.

 

[Thorsen]

you should check the docs that came with the PSU for the correct voltages

Then, you can either use one of these: Newegg.com - Rexus PST-3 Digital Power Supply Tester with LCD

or a regular multimeter: Newegg.com - GB Gardner Bender DM6400 8 Function Digital Multimeter

and here is a good tutorial: Power-supply troubleshooting with a multimeter | TechRepublic

another thing to check would be that all the components are seated properly... the RAM could have popped out? but this would still allow post I think....

If the CPU is not seated correctly, then the computer wont POST though I think (I could be wrong, but I will check)

Also do you here any beeps? usually if there are errors during POST, there will be beep codes:

ok i will try testing all that, about the multimeter, well i dont have one and i live outside of the us so its really hard for me to buy one so ill try witht the pther psu andd alll that stuff, and ill tell you if something worked, i cant get to hear any beps

 

[Dan011093]

tried installing thother psu and the same error appeared

 

[Thorsen]

Have you tried taking all components out to see if it will POST? disconnect the HDD, DVD Drives, and take out RAM

only leave the Mobo, CPU and Heatsink

Power on and see if it posts if it doesn't then the problem lies with the PSU, Mobo, or CPU.

Next step if it still doesnt POST is to see if the CPU is seated. You will need to take the HSF off and reseat the CPU and apply new Thermal Paste. If you havent ever done this there is a good tutorial here:

Here is another good Tutorial to follow for the motherboard installation in case you missed something...
