Hi, thanks in advance for any help.

This one's got me stumped, I've done 2 things to my computer recently, installed a new Power Supply & installed a new Graphics card

I did them both separately just to ensure that if any fault occurred i wasn't scratching my head wondering if it was the PSU or the GPU. Anyway, the Power Supply went from 300w Dell standard PSU to 620w Antec Eco Neo PSU. Which, from what i hear is a re-branded Seasonic M12II-620

The Computer had no faults during or after the installation of the PSU (Though, with the layout of the Dell Optiplex 3010 it was a pain in the ass to get in, i had to remove the MOBO!)

Here's my basic specs

PSU: - 620w Antec Eco Neo
GPU; - MSI/Radeon HD7850 (Afterburner)
Processor: - Intel Core I5 3.2ghz
Motherboard: - Dell Inc 042P49 - according to cpuz (Part of an Optiplex 3010)
RAM: - 4GB

The Problem: When i connect the VGA through the integrated graphics it informs me that a Graphics card is detected & i should connect the VGA cable through the graphics card. (Via a DVI->VGA adapter which came with the GPU) However when i do this, the computer fails to detect the Graphics card. (Monitor remains blank, no activity at all) I've also attempted this with a HDMI cable & a HDMI TV, but no luck. However, when i connected the HDMI cable to the integrated graphics it did not inform me that i should switch to the graphics card installed, the screen would simply flicker & remain blank. It would also flicker when i connected the HDMI cable to the graphics card, (but remain blank) which at least tells me the computer is detecting something.

With no Graphics card in, or connected but with no 6 pin PCI-E power cable connected, the computer boots up fine with the integrated graphics. (VGA or HDMI)

This is also the first graphics card to be installed on this PC

Steps i've taken

- I have updated the BIOS, among other things
- I have changed all settings within BIOS that relate to Graphics cards
- I have ensured that the Graphics card has it's Power Cable connected & is sat correctly in the PCI-E socket.

My next step is to take the GPU to a Shop & see if it can be picked up fine on another PC, i'd need a hammer & a chisel to get this in the other PC in my household.

If the shop finds it working fine, my next step would be to see if another, perhaps lower spec, GPU will work in my PC. (to rule out a bad port)

I'm here just to make sure i haven't missed any fundamental steps, i once troubleshooted a pals PC for about half an hour to find the power outlet wasn't switched on, which is the kind of story you read about online & laugh.

Once again, thanks for any help, i always try & keep these things short but it always turns in to an essay, sorry about that.

Hi, i've managed to resolve this issue. Apparently Windows 8 PC's come with `Secure Boot` & `UEFI` pre-activated, & this must be de-actived for any Graphics card that is not UEFI-compliant

UEFI is apparently what assists in the new Windows 8 PC's faster boot speed.

Once i turned off secure boot, & enabled Legacy, the system discovered the Graphics card without fault.

Thanks for the help though.

Can't seem to find how i mark this thread as solved?
