Is my computer too slow for Windows 7?

[t30power]

I installed Windows 7 RTM on my desktop:
Intel Celeron 420 @ 1.6GHz processor
1GB RAM
40GB 7,200RPM Drive

It was running fine Windows XP, but I decided to install Windows 7 to see how it handled. I had to download the video driver from the VIA site and Aero is working fine.

Below is the ranking on W7:


It works reasonably fast, but one thing I noticed, I tried running a .WMV file on WMP and the video does not play smoothly, the CPU usage ramps up to 100% and practically the video is unwatchable, unless I use Windows Media Classic which works in some way, but it is not smooth as in XP.

So, is that processor really up to the demand of Windows 7?

CPU is enough to run Win7 and doing surfing and word processing, but video watching is a fairly demanding task due to codec compressing.

The CPU is, but like Sprint said video decoding takes fairly serious processing power. Between the relatively slow single core CPU and the lack of a video card capable of video decoding, you don't have enough horsepower.

For giggles, you might try turning Aero off, that'll free some GPU usage that might get applied to the video.
Really though, you need a newer CPU. Depending on what sort of system you have you may be able to buy a cheap low end dual core and drop it in.
