Geforce 9600 GT significant underperforming after..
Hey,
I've had my system for about 4 years (haha as you can tell by my graphics card) and I have had no problems, I could run all games up to Crysis 2 on maxed out settings (though Crysis 2 was slow at times). About a week ago I upgraded from 2 giges of ram to 4 giges and from windows xp to windows 7 64bit. Yesterday while I was making dinner my power supply (Antec BP500U) seemed to have died, when i walked in i heard a flickering, crackling noise coming from the power supply and the computer seemed to to have limited power flowing through it as the fans were all running very slowly and the computer was not able to boot at all. I pulled apart the psu and it was full of dust, I also tried to locate the source of the noise once its cover was off, it wasnt the fan it was coming from either the yellow thing in the middle of the first picture of the site below (the site didnt let me use there insert there picture), or the silver bar thing under it.

I don't really know if this was a result of adding new ram, installing windows 7, or simply a coincidence. About 3 hours before the psu crashed i installed these drivers withing rebooting "Intel(R) 4 Series Chipset Processor to I/O Controller - 2E30", i don't know if that could have been the cause of the problem either.
After i pulled apart the psu and tried to locate the problem, i switched it with another 550W psu i had in another computer, im not sure the brand of this psu as i didnt look and at the moment its orinentated such that i cant see the label, and i dont want to disturb it.
Once booted up with the new psu windows said it installed some drivers. A little later i went into bad company 2 to try play, for some reason it installed direct x and thought that it was the first time i had played it which was weird.
I loaded up a game, it loaded as fast as it used to but when i spawned the lag was horrendous, i literally couldnt turn haha.
Back to a week ago, I had tested bad company 2 right after i installed windows and the new ram and it was 100% on max settings. After i tested it i updated my bios, which gave me a "CMOS Check sum bad load default settings" and i never tested the game after that. So it could be due to the bios change, i've reflashed the bios with 2 different versions and i get the same thing, i try loading up the performance settings and also get the same thing.
I've also tried reinstalling a clean copy of the nvidia drivers, but uninstalling the graphics card, removing the drivers, then sweeping the drivers using driver sweeper and reinstalling the drivers again. No luck
Sorry this post is so long, i tried to be as detailed as i could incase one of the steps i made caused the error. I really dont want to have to buy a new PSU anddd a new graphics card, i going to get a new computer next year, so if i have to buy both components i may aswell just get it now.
Does anyone know why this lag could be happening? Could it be the problem with the bios? The power supply not being sufficient, even though its larger?
Another subtle detail i could add is that i used speedfan and Rivatuner to see gpu temperatures (before i noticed the lag) and on the load of rivatuner it asked afew things, and i unticked both boxes, but thats all, i don't think anything got touched.
Thanks alot in advance
edit
Just checked, the power supply im using at the moment is a Powercase phkpow550080mm
+3.3v =25A, +5v=20A +12V = 30A, -12V = 0.5A and +5VSB = 2.5A
