Can a bad cpu cause artifacting?

[trismegistus]

I read somwhere that a guy with socket A Sempy has blown up his psu and cuz of that the comp started to artifact on desktop(all over the screen) as well as in the games.He brought the comp in some repair centar,and they said it was the cpu.They replaced the cpu and everything worked fine.They even gave him his old cpu.Do you think this is possible?

For my knowledge I would say that's false, the only way to get artifacts would lay in the hands of the video card. If you push the GPU or MEM to far with out supplying it with enough voltages it would just display artifacts. That is one way, another way would be high temperatures that can cause artifacts as well for what I know. Maybe it can be the CPU, but for what I know I would think it's impossible because the CPU is not video related.

maybe if he was using onboard graphics. But artifacts are usally gpu related

Sounds like the "geek squad" strikes again. I highly doubt that it was his CPU, as artifacts are graphical stuff. Sounds like a nice sale was made by the repair center, though Maybe the new PSU had a little something to do with everything working again, as well.

Yeah, it almost definiately wasn't eh CPU at fault. My guess is that they were "troubleshooting" it and found that he'd taken off the HS and reapplied some thermal paste and they decided that since he did, the processor must be screwed. Usually, when the CPU goes, the system won't boot up because of the errors it returns.

Replacing the PSU most likely was the cause of his system working properly again. If you know the guy, tell him to try out his CPU again either in his system, or another. Odds are that it will work perfectly.

The 'artifacts' are always caused by the GPU first if it's overheating or faulty. Meanwhile lockups and certain VPU recovers (or Infinite Loop errors) are often caused by overheating CPU or bad memory if I'm not mistaken.
