Aside from the obvious difference in the Processor speeds the problem is most likely a bottle neck in the HX5 which uses a 512 FSB versus the 833 FSB of the HS22. This should be minimal though. The second place I would look if the FSB isn't the problem is the RAM Type. They both may have the same amount of RAM but if the HX5 is using the slower DDR 1 RAM versus the DDR 2 that the HS22 uses you will have system degradation.

Lenovo 3000 N100 0768-FTG lap top need processor upgrade

I'm afraid you're out of luck, the motherboard is not capable of taking a dual core processor. Your only option would be to consider selling the laptop and buying a new one that already has a dual core processor installed.

Why my mouse and keyboard hangup when i attach my flash

It sounds like you could be low on memory or your processor is working super hard.

To fix this, first, check and see how much ram you have by right clicking on "My Computer", then click "Properties". Your processor speed and ram will be shown in the window. If you have less than 256 MB of RAM, or a processor less than 1.2 GHz, then you might need to upgrade your processor or RAM.

Processor load on biostar m/b

IT seems no problem with your specification, but only one thing less in this criteria. What inch does your monitor? This must be match with the specification of your VGA Card, The more resolution you can get the best performance of this VGA card you can achieve, try to higher the resolution of your monitor , don't only use 1024 x 768 , but try another higher resolution. The VGA itself cannot reduce the system perfomance, because your vga card has GPU (This VGA card has his own processor and memory) just like mini computer inside your main computer.Hope this things can solve your problem, don't forget to vote

  • When performance test is ran, the processor and other hardware resources are used as much as possible. So please check whether the processor gets over heat or any problem with memory modules. If the problem is with memory module, try to test it one by one running some memory diagnostic software, which can run on boot disk.

Take care.
