Build Advice Help needed! PC not working since new graphics card install

Hi All

I really need some help. I decided to upgrade my graphics card.

My previous setup was:

Motherboard - ASUS P7P55D Deluxe
CPU - Intel i7 -860 2.8- GHz
GPU - ASUS EAH5870/2DIS/1GD5 Voltage Tweak
RAM - Corsair Dominator GT 8GB (4 x 2GB)
O/S HDD - Corsair Force GT 240GB SSD
Internal Storage - Samsung Spinpoint F1 1TB x 5
PSU - Corsair HX10000W
Case - Antec 1200
Logitech G19 Keyboard

I have now installed an ASUS STRIX R9 390X Radeon.

Did this at the weekend, and all was working perfectly. Really please with it. When I had finished using it, I needed to install a game, so left it to install. Came back sometime later, and machine had gone to sleep. Nothing too unusual there. When the machine came out of sleep, nothing on either screen and also keyboard was showing no power.

Have tried various things to try and find what the problem is. Everything seems to be powered OK. I also removed the graphics card and tried booting. Keyboard sprung into life and a minute of so later heard the Windows boot up sound (obviously no graphics card, so couldn't see anything). When I connect the graphics card back up again and try turning the machine on, the machine kicks into life, but nothing on either screen, no keyboard power, and no windows boot up sound.

This was working before, so not really sure what's happened.

Any help would be greatly appreciated as I'm getting a bit lost now!

Thanks

I've had this a few times on my rig/s. Unplug the power from the wall, switch off the PSU at the back and then press the power button a few times to clear the power in the capacitors.

Try that.

If that doesn't work you may need to clear CMOS.

 

Thanks I will try that, and let you know....

 

No worries. If that works then your rig has an issue with sleep mode, so just disable it in Windows.

It happened on my all AMD rig and it happens on my X79 UD3 rig too.

 

I have noticed it before with my original setup. Would not wake up from sleep.

 

If it is that causing it then the power cycle method should work. It will turn the motherboard off and make it think that it's been shut down.

 

No joy with the power button...

 

OK then unplug the 24 pin for a few minutes and clear CMOS. If that fails to work I suspect the card is faulty.

 

It's strange that when graphocs card was removed, the machine booted OK.

 

Still no joy. Last resort, I put the old graphics card back in. All worked OK. Tried the new one again, same issue as before. Put old one back in again and worked fine again.

Is there any other reason of what would cause this, other than faulty card. ie non compatible hardware?

Obvious question, but do you have all power plugs securely fitted?

Other than that, the evidence points to the card being dead.

 

Always good to explore everything. Power leads connected, and get 2 white lights by connectors on the card. Assume white is showing all is good. When nothing is connected, there is a red light.

Strange that is worked at the weekend?

 

Does the machine boot to bios then black screen in Windows? If so you did not remove all old drivers and it's causing the issues.

If it does not show the boot window at all then try and clear the cmos.

 

With the new card, nothing shows on the screen. No input to either monitor. When I put old card in, it boots fine. Tried to find where the clr cmos was on the motherboard. Is it also worth checking for older driver conflicts?

 

could be a power issue, do you have access to another psu?

what was your original card?

 

Original card ASUS EAH5870/2DIS/1GD5 Voltage Tweak.

Also PSU is 1000W.

 

Also wanted to check the PCI-E connectors. Card has a 6 and an 8 connectors. My PSU has 2 X 6. Both of which have the additional 2 connector to turn the 6 into 8. Assume I need to plug them in as 6 and an 8.

 

Yes.

To be honest dude it's sounding more and more like you got a dud GPU. Mate of mine had a 980ti Matrix explode on him the other day...

If it worked and now doesn't I would send it back and get a replacement.

 

your assumption is correct.

just because its 1000w doesn't mean something hasn't gone awry with the psu. although at 1000w you would assume it has enough headroom to cover aging

 

I think that is the plan now. Replacement card. I just want to make sure I do everything right re installing when I try the new card.

1. Remove existing drivers.
2. Remove existing card
3. Insert new cards
4. Install new drivers

Any update/change on that please let me know.
