Ok, i baught a dell inspiron 531 about 8months ago now, and I have done some various upgrades since then. First off about 3months ago I upgraded my ram to 3gb of ddr2, everything went fine.

Today I baught some new parts for my PC. This included a PSU and new graphics card. The products i baught were -

Point Of View 8800GT 512MB GDDR3 256bit Dual DVI PCI-E Graphics Card

and a new PSU to be able to run this graphics card, which was -

Hi-Power Black 700W 14cm Blue LED Fan PSU - 20+4pin, 4x SATA, 4x PCI-E

---------------------------------------------------------------------------------------------------------------------------------

Ok so I began replacing these two components into my PC. I added my PSU replacing, my hard drive cable, the 24pin cable into the mobo and my cd/dvd drive cable (sata). I noticed when removing the old PSU i had an extra 4pin square area, I left nothing there for a while.

Then I replaced my old graphics card - my Nvidia 8400gs, I was unsure about the 6pin cables at the back (it came with a cable to plug in, however I didn't connect it to this, i Used my 6pin cable which came with my PSU)

So now this is when my issue occured, I powered up my PC and my PC monitor was like on a standby mode, it wouldn't switch on, so i powered off and checked everything and then replaced my new graphics card with my old one(to check if it was a PSU issue) - The same still happend, my PC monitor wasn't switching on.

So i switched back and now the PC system will not even turn on, does anyone have feedback they can give so I can fix this problem!

Thanks.

Hello and welcome to PC Help Forum.

Mmmmm,Ok you have a 24 pin port on mainboard?Then you need to either plugin a 24 pin cable connection or a 20 pin+4 pin.

Aslo you need to plugin the seprate 4 pin on mainboard located elsewere.

Are you able to upload pictures of how you are connected?

Little confused on the above.Is there not a 6 pin on mainboard?Or did you bypass mainboard connections?You plugged into power supply?Not sure?

It seems you have not connected all the power connections to mainboard?

Pictures would realy help.

I have a 24pin on the main board, and a 4pin located on the other end of the motherboard. The cable that came with the PSU was a 20+4pin (the 4pin can be broken off if needed) - I also have a few 6pin connects 8pin and 2pin connectors, can I use one of these to put in the seperate 4pin area?

I can take some now, bare with me

Ok few images -

If you need anything more specific ask

By the way it was the 6pins on the back of my graphics card

First pic both plugin the 4 pin plus 20 pins connection to second picture.NO do not use any other connectors to enable this power supply only the 2 I stated.


Is there a seprate 4 pin socket on your mainboard located else were?

Is the CPU power connection plugged into the CPU fan port on mainboard?

Just getting your computer specs.

Sorry pics are a little bright.Let me look at the others brb,
