Unhappy Graphics card problem after upgrade
Hello~

A few days ago, I upgraded my my old GTS 250 to a GTX 550ti and added 4 GBs of RAM as well. I opened up WoW to test it and noticed that it would go from around 60fps to around 10 in a 2-3 seconds span and go back up again(the game would be all jumpy). This would happen every few seconds. I deleted all the drivers, used Driver Sweeper, restarted computer and installed the latest driver again and the same thing would happen. Today I took the card out, along with all the ram, made sure that everything was installed correctly and put it back together again. I also re-installed the drivers a few times and updated my mobo's chipset and still the same thing is happening (this time with Skyrim so I guess it's not a patch or anything). It's fan is working and all the other fans/heatsink as well. I defragmented my computer as well even tho it didn't really need it.

My specs:
XFX 750i sli mobo
4x2GBs of DDR2 RAM (8GBs of RAM)
intel core 2 quad q9400 @ 2.66 ghz processor
Coolermaster cd 690 case
Corsair power supply - 750 watts
Thermaltake V1 heatsink

I even switched game settings to lowest and still have the same problem. I'm about to just put the old one again :[

Adding RAM would not have made any difference in how well the graphics perform. Most of RAM over 4 GB's will not be used. Defragging won't, either.

But what about your power supply? Is it large enough? Is there a supplementary power connector on the card and if so, is it connected?

Oh I knew it wasn't going to improve graphic performance. I just thought it was worth mentioning, just in case. I honestly dunno if its large enough and nope, it didn't have a supplementary power connector.

Just noticed I said 650 watts - it's actually 750, sorry.
