Screen goes to black

[Jay]

I have had little trouble runing Vista. In fact I kind of like it. Just
recently upon awakening from sleep my desktop screen comes on normally for a
couple seconds then it goes to black for a couple seconds then returns to
normal. This has not caused any problems yet. Is there something I can do to
"rebuild" Vista? Is this an operating system or a hardware issue? Daily I run
Disk Cleanup, Windows Defender, Trend Anti Viris software and weekly I run
Defragmenter. Is there anything else I need to do?

I've no idea about the issue that caused you to post, but...

Daily runs of all of those is hardly a good way to spend time.

Disk cleanup... fine. Once a week would be more sensible.

Defender: once you've scanned, let it do its own thing on its own
schedule.

Trend AV: same as Defender.

Defrag: same there too. Defragging will occur automatically in the
background.
