Random Spikes of Lag (CPU Lag, I think)

Hello,
I have a out of the box Dell Inspiron 620, with a new fan and an Nvidia GTX 550 Ti graphics card for gaming, that is the only upgrade I have made. I am having some issues, though. My computer (either right at start-up, or in heavy gaming) will start to lag, and by lag, I mean everything lags. My sound starts going all slow-motion and VERY static-y, very hard to listen to music. My mouse skips behind, making it hard to scroll a site and click things. My keyboard is very unresponsive (I can type a whole sentence and it will miss many letters.) And finally, my game I am currently playing feels like it has about 20 of the same game running causing my FPS to go to 60 down to 20 FPS. Only things I can think of are my PC is over-heating, but it happens right at start-up! Also, it could be a virus...but I have ran so many scans it isn't funny. If you have a scan you think could help, please let me know. The lags spikes cause my CPU usage to skyrocket to almost max, which isn't right. Also, I have 4 gigabites of RAM, and sometimes just at start-up when nothing is running at all, 2 gigs of it are already gone/being used...I haven't even ran anything! If I think of anything else that occurs, I will be sure to post. But yeah, I am not sure if this is a common thing or what...but if you have any idea what's going on...please help! It is making gaming/watching videos/typing a paper 1000x more annoying than it should be. Thanks!
 
Out of the box any Inspiron has no more than 305 watt PSU, and Nvidia GTX 550 Ti requires at least 400 watt and additional 6 pin power connector!
Can you please clarify this! Otherwise something is not right.
If you made them work together somehow - this is the source of your problems.

Hm..it still did this weird thing even when I didn't have the video card plugged in...but I will still check out some power supplys and get back to you with more info, short on time atm. Thanks for letting me know of this!

 
Can you please provide complete info about your PC, like processor model, memory amount, OS, form factor, is this mini tower or any type of small form factor (slim looking), and exact model of video card. Also, check if this card has 6 pin power connector, if it does, it is not suppose to work without this? That is why please carefully check and provide as much info as you can, thank you.
