I have a new Dell Inspiron 1520 note book PC; It was having problems on start up like heavy monitor flickering after Log On and long time to start. It was giving unexpected shutdowns. The service from Dell and agents was not helpful.

So I re-installed Vista from the CD (that deleted all Dell software). and updated drivers as required. Then all start up problems vanished. But there is one problem now. After most Vista updates, it goes into black screen (repair mode) during the re-start process. What can be done? Can I avoid updating? Will it cause any problems?

After the "repair" (nothing really) and booting, it says the updating was OK and works normally. Pls advise.

I pasted the text below of the Windows Security Center popup that eventually requires me to spend for a repair download. The download site is last. Do I need to spend this money to repair it, repair it some other way for free, or ignore it? Edward
