We might instead put this computer into semiretirement up in our sons' bedroom (where it won't be put to such constant and demanding use), and buy a new computer for downstairs (we saw a rather nice Asus bundle in this week's Best Buy ad for approx. $850, with a good graphics card already included). I've got most of my important data files already saved to thumb drive, so switching over shouldn't be too difficult.

The computer may still be covered under one of Best Buy's Performance Service Plans, so perhaps warranty service can get it repaired. Besides the screen flicker, I was also getting blue "crash dump" screens. I did a system restore to factory settings twice this week (once using the recovery partition, once using the recovery discs I had fortunately made before all this started happening). I've got Internet access, and I can run DVDs (without flickering!) now, but games? A link to HP's WildGames service was part of the factory settings, and I can access those; however, although I can install games from discs (such as Civilization IV), I can't load & run those games. (As long as DVD movies will still run OK, though, that may be sufficient performance for "semi-retirement" in my sons' bedroom, since they generally just watch movies in there, and play games on other computers in the house.)

Flickering can be caused by multiple things:
1. software and/or drivers
2. physical issue with video card
3. physical issue with computer (e.g. power issue or slot issue)
4. Monitor power cable / monitor itself going bad
5. external issue (e.g. speakers or fan too close to monitor) Note: usually only relevant to old CRTs
Easiest step is to simply move the LCD to another computer to see if the issue continues. If it follows the LCD, then you know what the issue is. If not, then you need to think of when the issue started. Was it after a lightning storm, or was it after a software change?
