Vista - Flashing screen

I've a problem with my Acer Aspire 5670:
After updating my system from XP to Vista Home Premium the screen starts
flashing and the gadget tells me that my CPU is, for example, in use for 95%.
I've tried to update the system, but it doesn't help at all.
I've been searching for a solution, but with the use of Google I couldn't
find any clue.
With the Windows TaskManager I couldn't find the cause.

Please, can somebody help me with this problem??

System:
Intel T2300 Dual 1.67 GHz
2048 MB
Ati X1600 128MB
120 Gb Disc Space

So, task manager did specify which process was running your CPU at 95%?
Under applications it showed no open programs on which you might "end task"
one at a time to see if any list programs were the offending application.
Have you checked Event Viewer under Administrative Tools as there might be
some error, especially one that repeats regularly.

Have you run a virus scan on your system?

If you remove that gadget, the CPU gadget, do you still have the same issue?
