upgraded cpu/video, worse performance!!!

[slick20066]

I upgraded from a AMD 3700/7800gt to a AMD FX55/7950GT KO, now my performance is worse while playing BF2142, i even reloaded windows xp pro, it didnt help, I did notice 2 things though, i had a hard time installing my viewsonic monitor drivers, it keeps going back to default/analog monitor, also the boot up time is longer than before, bad monitor or possible bad power supply all of the sudden?

thanks

You installed new drivers for the 7950, right? Cleaned the old ones and installed the 93.71s?

I reinstalled windows, clean slate!!, my monitor is acting weird, the driver seems to be messed up, 1 minite when i access nv control panel it says a91f monitor and then it goes to analog monitor, is my monitor going bad?, it looks ok, its a veiwsonic a91f,

Call me crazy but I don't think your monitor would have any bearing whatsoever on your computers performance. If anything I'd worry about your vid card or power issues.

EDIT: Btw, bad OS cd's have been known to cause headaches like this before. It might help if you tried another OS disk.

Damn good question.

What are the spec's of that PSU? 12V rail(s)?

 

[slick20066]

my ps is a thermaltake 500w

He means the amperage on the 12V rail, not the overall wattage. Since everything else seems unchanged, I can only blame the PSU.

This may not be helpful, but A643700+/7800GT to FX55/7950GT is not much of an upgrade, especially considering how much money you probably spent on it. Would've been wiser to keep the CPU and move to a 8800GTS
