Hi, yesterday i decided to upgrade my wireless network card in my laptop, i brought an Intel-dualband-ac-7260 card. But after the instalation, I booted the system, it's was going slower than normal, and when I entered the windows interface, everything was going in slow motion, every anymation did the same it was just 10 times as slow.

I got the drivers on and then rebooted the system, but it said something was broken and it had to run a repair, so I did that but when i entered Windows again it was still in slow motion.
The very weird thing is, the "slow motion" thing also happens when i enter the BIOS and when the "windows is loading" logo comes, it all moves like it was 0.1 speed.
The laptop is an Acer aspire 5942G

Specs
Processor: Intel Core i5 520M
Graphics Adapter: ATI Mobility Radeon HD 5650
Harddrive: unknown

There it's really much info about the specs. Is this enough info, or have i missed something?

I am aware that I should do that, but I don't have the right screwdriver for that right now, and I fear that i might break the screws without that, so i just wanted to know if anyone knew anything about this problem.

*In first post it should say "there isn't really much...." sorry for my english

Actually, i just changed to the old one, and it didn't have then probelm, then i changed a back and it was there again, but it's not as bad always, some times it makes the computer take 10 min to start(usually takes 1) sometimes only 3 min.
I guess it's the new wifi card, but i would really like to know why, and if i can do anything about it

I got it yesterday, it's totally new, and yes i can send it back. But that still makes me wonder why it makes my whole system go in slow motion.

Hmm, just checked and honestly, nothing, csrss and dwm sometimes jumps up to 2-4% useage, but else it's just google chrome using its usual 2%
I got a constant load from 2%-10% and thats what i normally have, do you think it could have something to do with the drivers?
