Overclocked P4 celeron

Last night, I tried overclocking my celeron a bit. I overclocked it from 2.4ghz to 2.8ghz. It ran flawlessly. I then wanted to get even more out of my system so I decided to overclock my gpu by about 25%, again, it ran flawlessly. I figured I could try even more out of my processor so I stepped it up to 2.9ghz, again no problems. My question is this: Am I harming my components keeping them at these speeds? I leave my pc on 24hours a day, should I not do that with it being overclocked like this? Can I melt my gpu going over like that? I havent gotten brave enough to overclock higher on my celeron,at what speed should I probably call it quits? I have all stock cooling, am I being a dummy for doing this with stock cooling? Any comments and/or suggestions would be very welcomed.

the northwood celeron is a very good overclocker, it is common to get 3.0ghz out of a 2ghz celeron, probably your 2.4 will max out in the same area, if not higher.

If you are not getting artifacts in games than overclock your gpu further, it will let you know speeds that it doesnt like...

BTW keep the cpu temp below 55c and your fine...
