Check your monitor & graphics card to see where the problem is.

Check and see if you have any update driver for your graphics card to suit Vista:

i tried all suggestions and still having no luck even turned off the security desk top as someone else told me but that doesn't work either vista is a real pain.

In the cmos of the computer disable all the power saving features ,and also in control panel network and sharring ,and manage my connections in the properties of that disable all the wake on lan ,and allow this device to shutdown the ocmputer. YOu could do all this in safe mode you hit f8 after the ram checksum screen


Upgrade the bios see if there is any updates for it. If all that still dosen't work see if you could boot into safe mode ,and goto control panel adriminstrative tools ,and event viewer see if there is any errors if so paste them here.
