The Seti screen saver is explained here: http://seticlassic.ssl.berkeley.edu/screensaver/index.html

Also the new site have some info:
https://seti.berkeley.edu/setiathome/glossary

Read "Procedures for Public Announcement" - the last part "... it is important that participants in the SETI@home project do not get excited when they see signals on their screen ..."


(The page about screensaver on the new site still do not exist:
https://seti.berkeley.edu/setiathome/screensaver

I don't know if they will write new page based on the current screensaver or will just Copy/Paste the info for seticlassic
(if new info - it will be almost the same, only pictures different)
)

"SETI@home: Glossary of Terms"
http://setiathome.berkeley.edu/sah_glossary.php

It is unclear where you "have a white colored signal" so read 'Radio Frequency Interference (RFI)'


Since there are billions of "signals found" so far:
http://setiathome.berkeley.edu/sci_status.html

... anything you see on the screensaver is only pretty picture and is nothing to be excited
It may be RFI or a test signal (yes, they sometimes inject test signals to test the correctness of apps)

In simple terms (I hope)
The screen saver is a representation of the data as it is being processed. The height of peaks are just representations of the real data, as are the colours - what are just there to make it look pretty.

The actual results are held in a file, and transmitted back to the servers for validation and further analysis. SETI@Home works on the basis that a "real" signal from ET will not be single event, but will repeat over time (months or years) and will always come from the same place in the sky.

Not that I think it is real signal but if you want us (we, which respond here, are just 'normal' users like you) to see what you see you may:
- instead of screensaver use [Show graphics] (select 'Running' CPU task first)
- by Alt+[PrintScreen] Copy the window
- Paste in some program and save as .PNG

I use for this IrfanView
http://www.irfanview.com/

Upload the .PNG picture to some site and give the link, e.g. on:
http://uppix.com/

Like this (old pic from 14.02.2009):
http://uppix.com/f-SETI_455153ec000189d13.png

P.S.
Sometimes it is possible to hit [PrintScreen] during the screensaver and get the fullscreen picture but I think not always.
I don't use the screensaver (my apps do not have it) so don't exactly remember.
The above picture was made (if I recall what I did in 2009) during offline test (not in BOINC)

Windows Paint saves as PNG and JPG these days as well. Also in Windows 7.
