No Vid Signal

post #1 of 33
Thread Starter 
I just installed a waterblock onto my graphics card, along with an overall new WC setup, but now I can't get a signal from my vid card. I can't help but feel that I just forgot to plug something in; however, I cannot conceive of my breaking it. I can't caugh up the money for another 7800.

It appears and feels fully seated. When I boot the computer, the graphics card does not get even remotely warm, so there's some concern there.

Anyone have any ideas?

You damaged the GPU die, most likely.
The 7800GTX is probabally dead.

Yea... I'd try and RMA it, but otherwise you may have to buy another one.

dont cry just yet mate. lets take this one step at a time shall we. is your power plugged in? if i am of knowledge i would say your card requires the extra molex connector. is it connected? and is ur 12V rail connected to the mobo?

if answers to both of the above is yes.then i would suggest that u unplug the card from the slot and slot in again. check to see if it is working. if it still doesnt work, just unplug ur water pump (cut of power supply) and then switch on ur system. just for like say 1 minute to see if its a problem with power. let me know what happens.

Yes do what is said above, if that doesnt solve your problem then it sounds like you have damaged the die when placing the water block on it...unluky man could happen to alot of people.

aww man... I have all the power connected, and the computer is running, but still no vid signal and the card is also still very cold.

Unfortunately, I damaged the stock HS upon removal, so my only option is to get a new one before I replace this one. It's a sad day.

I also turned off my PSU and rebooted, but no luck there either.

well mate like i said one step at a time, try and unplug the card. take it off clean and then plug it back again and switch on the power to see what happens...electronic components as fragile as they are dont just die like that. do this and come back here to update mate.

Dont hate me, I know it's a dumb question but did you connect the dvi plug to the computer? Did you try the other dvi plug?

ok, I unplugged/replugged the vid card, made sure it was connected to the monitor, but no go.

I plugged in the stock HS fan to see if it was getting power and the fan cued on like it was supposed to. So, I assume it was getting power. No vid signal. I tried both DVI ports, but no.

EDIT: I also tried unplugging the pump from the system, but no go, either.
