8800 GTS 512mb OC overheats and crashes

post #1 of 15
Thread Starter 
Hey all, I'm new to the site and the reason I am here is with a major problem regarding a recent upgrade I did. So heres the story.

My pc setup prior to crashes was:

intel e4500
EVGA 680i sli
2 x 2GB Patriot Viper RAM
2 x 8800 GTS 512 mb OC running in SLI
650 OCZ power supply

Now funny thing is that everything worked fine before. Was running ok with random crashes after prolonged gaming. So I decided to upgrade CPU to the e8400. Once I got it I also realized my pc was not utilizing all my 4GB because it was in 32 bit windows 7. So I chose to get my 64 bit upgrade as well.

So I installed the 64 bit, everything booted fine. Next step was the cpu upgrade which i planned to couple with a redo of the thermal paste on the NB and SB heatsink since i read online that that tends to go bad and it was running my system into the 75+ degrees on the MCP. I took out the board, removed the heatsinks and reapplied the thermal paste on the NB and SB followed by applying the e8400. I reassembled the system taking out one 8800 gts since the new boot deleted all drivers.

Now this is where the problem kicks in. System crashes as soon as you get the windows loading icon, and a bunch of multicolored squares pop up...now this is on the new 64 bit load. I have a second drive for backup that has my 32 bit running clean install no internet. That drive boots fine but when I load a graphic intensive movie it crashes almost instantly, but with a black screen.

I have no idea what the problem is, so i thought maybe it was a faulty 64 bit install. I then proceded to reinstalling windows 7 64 bit on the same drive, which loads fine but 15 % into the new install it gets BSOD and tons of multicolored squares again.

I have a feeling it is the graphics card necause when I touch its side my fingered almost get burned. Only wierd thing is that it happens even when i swap one card for the other thinking that only one card is broken. Does that mean both cards are broken? Or could this be a different issue? I can boot into BIOS no problem and my cpu temps are around 40 degrees, so i dont think i applied cpu incorrectly. Could it be the motherboard?? Any help greatly appreciated.

Have you updated the drivers to the 64 bit ones? Im guessing you may need to change drivers for your card if going from 32 to 64 bit. I have one of those cards in another rig that idles around 57 and loads around 80, its always hot, but never crashes.

Just saw what PSU you are running.

The 8800gts is a power hungry beast. Even though its old, the 2 still need a ton of power. Try the install with just one card.

I have been doing the install with one card. Problem keeps occuring on both cards even when i swap them. I dont think the power is lacking, I have beeen running sli for 2 years prior, just upgraded the CPU.

I have one running on a Antec EW 380w PSU, its fine. I would say 500-550w is enough for SLI.

EDIT: You may be thinking of the other 8800GTS like the 320-640, those are more power hungry and hot.

As a first step I would clean up the GPU's and reapply TIM to help lower the temps. Do you have another system to try the e8400 in to verify its integrity?

As a second step, I would re-aply the TIM to the NB and SB, you may have gotten too much or too little on them and they are overheating as a result, rendering your system unstable.

Your Right, I just ran the 512's mentioned through the psu calculator in my sig and it says that a 360w power supply is recommended for that processor, a highend mobo, 2 sata hdd's and the 2 8800gts. the other ones needed a 590w psu, big difference.

I have no other system, just this one. I don't think the cpu is the culprit here. I've looked online through everything i could and its just stumping me everywhere. Tonight i will try repplying the NB and SB heatsink. But i still feel like its a GPU problem. I've cleaned it thoroughly as well. Will new TIM actually help on the GPU? If i touch the metal heatsink on it i get burned, so doesnt that mean it has good TIM?

Did you boot it up with only 1 GPU in? And if that didn't work, what happens when you put the other one in alone?

Well judging from what you said you can be almost certain its graphics related. Do you have another monitor cable? Or if you are using an DVI to VGA adapter is it fastened in all the way?
