Hey guys,

I have been searching around the internet for a solution to this but there is nothing I can find that is helping my situation.

I took my two graphics cards, I believe they are GeForce 9800GT or something like that (Sorry I'm not very good with the technical stuff haha) out of my computer today to clean the fans underneath them. Basically I play a game called League of Legends and I was getting a fps drop from a stable 60 to around 5 every 60 seconds which lasted about 5 seconds, which in this particular game can make or break a fight or whatever. So I opened up my PC to remove dust and all that to see if it improved my FPS. I saw that there was a LOT of dust in the CPU fan and the two graphic card fans, so I removed the two graphics cards and the CPU fan and cleaned them thoroughly. Now I don't know if I put them back in correctly, or what, but I don't see how I could have put them back in wrong. All it was was one cable leading into each one with a SLI bridge thing between the two of them.. Pretty simple. The CPU fan is back in fine as well, thats an Intel fan (i dont know the specific one) with these weird twisty locks on it which I removed and managed to replace fine and its stable. I ran power through my PC with the casing off to see if the CPU fan and the two graphics cards fans were running with power going to them and all 3 are running fine, so I literally have no idea why suddenly after I have taken them out and put them in exactly as they were my FPS has kind of flipped. It used to be 60 seconds of 60 fps dropping to 5 fps for 5 seconds, now its 60 seconds of fps at 5 with 5 seconds of 60 FPS, which makes every single game I play unplayable.

Please, any help would be much appreciated as I'm clueless as to what I have done here..

Thanks,

Simon

Try to make sure the cooler is on fully. If it won't go on right, then you may have to replace the cooler with one with a better mounting system.

I know you probably don't want to hear that but I am 99% sure that is the problem.

The CPU throttles down its clock to prevent damage once the temps get high and that causes low framerate.

It seems to just be a plug with a wire leading straight into the computer, there isnt like, a box built into the wire if you know what I mean? the thing that ususally has all the info. This is just a wire.. haha

Oh okay I will check that out first thing tomorrow. The damn rotating fastening clips on that fan were really odd, I had to press them in then twist to lock it in place, and i think one of the four clips didnt go in properly and i was scared of exerting to much force on it.

I would suggest a tech friend or take it in to a tech shop to look at it. Unfortuantely your not familiar with alot of the necessary information to 'diagnosis over the internet'. You really need someone 'there' to take a good look at it (far as I know you could have put the cable backwards but nothing I can ask/you look at would tell me that). Good Luck.
