Original Title: Help please

I am not sure what the problem is but something appears to be running or trying to run in the back ground I see a quick window pop up about every 30 sec but it flashes to fast to see what it is I have noticed it causes internet and othere programs to also refresh  how can I delet this or even find out what it is I had thought it was Google Chrome because I also get messages stating that is has crashed and I have removed it but still get the messages as well
