hey guys, my 7970 was working great with the accelero hybrid 7970 but one of the mini heatsinks I noticed fell off so I decided to re attach the heatsink and re liquid pro the gpu die and put the case back on, come to find that my screens get no signal from the gpu and windows wont boot if I have the power supply connectors attached to it even if I use the GTX 570 with the monitors... however if I remove the power supply connectors from the 7970 and use the 570 windows boots fine... whats this mean?

First thing I'd try would be to take the card back out and make sure none of the heatsinks are touching anything they shouldn't be. Check to make sure the Liquid Pro didn't spill over the GPU onto something else. Also make sure the cooler isn't on too tight (over-tightened).

Check the power supply inputs ..looks like a short or no power to card Fans running?? ... Did you flip the OC's gpu1 switch?? Page 45 OC manual.. If you have power then prob some Liquid Pro on the GPU or card. I would Strip it down & give it a good cleaning both sides with some 99% alcohol then let it air dry for 24 Hr or give it a blow job with a WARM air dryer .... STill no joy then RMA
Good luck F

LED code? no the monitors haven o signal on the gpu at all and if I use my 570 as the host card the monitors turn off when you get to password screen but shows windows 8 loading, only iff I remove the power supply connectors from t he 7970 will my pc fully boot, if it is a short, ive already cleaned the pcb front and back and with a que tip to get the smallest places... how can u fix shorts?

well the gpu fan turns on the fan that's plugged into the 7970 pcb so power supply is getting enough power to the port that runs the fan

Try booting to dos & see if atiflash can 'SEE' the card ... looks like the ati drivers don't like what they find when they load

yes but this is just when the 7970 is used as a secondary card, nothing at all happens when its used as main

With the NV card as primary you will @ least have output to see if the ati card is alive enought for atiflash to see it ...if not IE 'no adapter found'... then you will need to look at the power supply chain to the card ...from the input plugs through the Vrm's to the gpu.. to do this you will need to know the read points & values ....witch are almost impossible to find .... I'v tried

If its not booting with the 7970 alone, I'm not sure if its 53 or 63 led code if your using the asrock OCF in your specs the card is dead

So just try the 7970 alone if you haven't yet and see what the led code you get
