widows 7 cpu through the roof with lan conected

Hi new here have just installed windows home premium but cpu is idling at 80-90% I have found if I disable Lan drops to 10% max. glad of any advice.
Cheers

Hi have updated system specks The lan is an on board lan has been fine till now
Guess who threw out a seperats lan card the other week spose
I assume specs will auto ad to this

Open your task manager by right clicking on the task bar, select Processes tab, click on the CPU heading until it orders the list by highest to lowest, then watch for the Process that is spiking the RAM, right click on that Process to select Go to Service and note the Services which are highlighted. Research these Services (or post back) and it will reveal via the process of elimination which one is the exact problem.

To get a more exact reading with a better GUI, download and run Attachment 33580.

Hi
Nothing marked as a problem new driver was one of updates I down loaded after installing W7.
Down loaded program sugested got the following readings
System Idle 35-39
ainterupes 3.85-8.5
DPC's 16-31
System 16-38

Just watch the processes and isolate the one which is spiking your CPU


You can also reinstall your LAN card driver by uninstalling (not software) in Device Manager then restarting computer

Did Windows UPdate deliver a new LAN driver (it frequently does)? Check for newer driver in Custom updates and on LAN card's website.

• start task manager
• click on processes tab
• click view menu
  > select "Select Columns"
• check
  - I/O Read Bytes
  - I/O Write Bytes
  - Command line
• Click OK
• Click the Top of the columns "I/O Write Bytes" or "I/O Read Bytes" to sort them for easier reading
• Check to see if a process is going haywire
• If something has transfered alot expan the "Command Line" column and see what is doing it

Did you reinstalled the driver? Else remove it and restart. Maby it wil do the trick

Good luck!
