I just put a waterblock on my 9800Pro and things aren't going so well. It worked awesome at first, no problems at all. I just got back from class and my monitors wouldn't come out of "sleep" mode so I restarted my computer and get to Windows and everything is okay again but about 5 minutes into web browing the computer locks up. I restart again, in Safe mode this time, and XP says that 9800 PRO is responsible for the system instability. Do I not have the GPU block on it properly or what? It's a DTEK block with Arctic silver between. Processor is watercooled at running at 34 degrees in same loop. Drivers are the 4.1s. The card worked great before the watercooling except that it would never turn off my 2nd monitor (it would go screensaver to desktop and my other monitor would go screensaver to powersave). It was never overclocked and is not now either. Any ideas???? Thanks...
 
Sounds like a heat problem, even though it doesn't make any since.

I'd suggest re-evaluating the contact between the water-block and the processor on the vid card.

Is there anything special I need to do? I took the old fan off and cleaned up the chip, applied AS5 and bolted the new block on. I guess I'll take it off and clean everything up good again and try to re-do it.
 
put some ASx on yoru core of your video card
do not put any on your waterblock
Mount the waterblock
remove the waterblock
if there is no thermal paste on the bottom of the waterblock, you are not making good contact due to the shim

either -
remove the shim

Mod the shim

or

Mod the block

You could use thicker thermal paste, but it will be a limiting factor to your oc. Good luck!
 
i'd say try reseating the block and se what happens. it ounds to me as if there is no propper contact between the block and the core
 
I washed all of the old AS5 off of the chip with 97% alchohol and re-did everything. I went to the hardware store and picked up some TINY machine screws/nylon washers/bolts and re-did the mounting hardware for the block (I didn't like the stuff that DTEK supplied because it only let me thread the nuts about 2 turns before it was tight). Everything seems to be okay right now, is there any software that will let me check the GPU temp?
 
If everything seems ok, let your pc run over night.

You're probably fine. Mostly likely part of the block was touching the GPU, or not enough TG, or maybe too much. Who knows. But sounds like you got it all fixed.
