Re: CPU Speed too slow
your sys is really so good.
check in task manager identify some unknown proess .
they are virus.
clean all temp files.
disk cleanup run.
scan your sys with avast,quick heal ,symantec one bye obe with update definition in safe mode.
then u get some malware and viruses.
then delete it.
after that run chkdsk utiliity.
then defragmen all drive
now your sys really speed up.
best of luck my friend.

The processor is throttled by a process called speed step. This slows the CPU to save power. The same process is used when the processor overheats, and the system throttles to manage the heat production.
So the heatsink and cooling fan should be replaced as the first step in trying to resolve the process.
Ok. Fear not. You CPU is running at its native speed, it is the fault of Windows reporting the actual CPU speed. If you stop in the BIOS, the real speed will be reported there, the same if you run Linux.
Have you tried right clicking on the desktop (opening Display Properties), clicking on Screen Saver tab, Clicking the Power button, and setting the power schemes to Home/Office Desk? If its set on laptop it will reduce the processor speed when running on battery. I have noticed that even with it plugged in that some times it will run at half processor speed. Try that out.
Check in the BIOS to see what processor is rated at (upon power-up of laptop hit F2 key to enter setup menu). Depending on what model Centrino you have, the speed rating should be at around 1.2 GHz or better. If speed checks out in the BIOS then run diagnostics on laptop to see if the motherbrd has a bottleneck issue. To do this, hold down the <FN> key and then push the power on button. Problem could be either your processor or motherbrd.
Is the new RAM you installed the same as what you took out? Are they both PC2700?
Is your laptop running on battery when you're testing to make sure you CPU speed is accurate? The laptop usually ramps down the CPU speed if it is being run off of just battery. Plug it in if this was the case.
Also, the Gateway and eMachines laptops I have encountered have all been notorious for displaying the incorrect CPU speed at times.
I would suggest putting your new RAM in, make sure the laptop is plugged in, and boot it up. This time, let it idle for about 10 minutes and then check your CPU speed to see if it has updated correctly.
