Hp pavilion ze4560us processor slow

I had an acer aspire 5335 that did the same thing, do as I say... CTRL+ALT+DELETE and open task manager. got to processes. Id there are many of them from programs you don't have or don't recognize you could have viruses or unneeded processes. try ending them, they usually never close by themselves and require you to do it as said. they could be slowing down your computer to this point. If not then watch the performance on idle with no tasks running. if the cpu is jumping from a low number like 10% to 80%-90% non stop you might want it to be checked out.

First, scan computer for viruses. If scanner doesnt find anything look at the task manager for the useless processes. If it doesnt work there is help for restoring. http://windows.microsoft.com/en-us/windows7/products/features/system-restore Sorry my bad english =)

check your system performance thru task manager. check for CPU usage. usually COU usage is 1% to 10%. if your CPU usage would peak from 10% to 100% there is a huge possibility that there is program running on your computer that eats up your memory. Or it could be spyware/malware

Try running Spybot (http://www.spybot.de) and avg on it. run Spybot several times (rebooting after every attempt) untill it finds nothing. If you built the machine are you sure that the processor heat sink is correctly installed and not over heating? What is the speed of the drive?

dude usb 2.0 was released way back... i believe the necessary drivers have not been installed... you better go to device manager and try updating the drivers... it would have option to check online... post here if u need more help...

When you say it's slow what I often found is that
1.not enough memory on your laptop
** so your CPU have to use your harddisk as memory,instead of working directly your CPU have another work to manage thus cos your system to slow down.
** you can check memory usage by right-click on your taskbar and click on Task Manager.Go up to Performance and check
Physical memory and see your available memory.

2.use more than one anti-virus program.Its just like before your work has been check by one program and now somebody is calling your same work to be recheck.Thus cos your system to become really slow.

3.Something is running all the time.A virus or something is running all the time.Shut it down by right-click on your taskbar and click on Task Manager.Go up to Performance and see CPU
usage that its 100%!!!! If so go up to process tab and right click
on the process you think is creating problem and End Process Tree.

3.The combination of not enough muemory and also not enough
harddrive space.When I say not enough harddriver I mean really low about 100-300 Megs.

so in your case not the problem with Harddrive..cos you have 1.5G

takecare.
