I have a 900 Celeron CPU. It's been a 900 Celeron since I got it two or three years ago, and I assumed it still was. But I just ran a Belarc test on it and it says it's a 600Mhz Celeron. Que? I asked Sis Sandra to do the same test and it came up with the same result. Yes, it definitely used to be 900Mhz, I wasn't ripped off.
Should I fill out a stolen property report?

If someone found 300Mhz, how would I prove they were mine? What's going on???
