    Hi all,

    Last week I had to reinstall the XP on my E1505 notebook due to a trojan virus which was opening browser windows with some random ads. Anyway, did a complete format of the hd, installed clean, installed all drivers, now I have noticed that whenever I run something it gets assigned to only one of the CPU's (always the left one in the task manager). One quick example: if a try to extract a 500mb file from winrar it takes about 15 min, one cpu stays at 100% during the process, the other one fluctuates at 1% or 2% and task manager shows the utilization to be 50%. Before it used to take only a couple of minutes for such tasks and as far as i remember both cpu's were equally working. This problem is happening for all apps including bootup of windows which also takes considerable time now because one cpu keeps staying idle.

    I dont think one cpu is damaged, i ran some utility tests at bootup which passed both cpus plus occasionally the second cpu will show some activity. I am guessing windows doesnt recognize the dual core, or something needs to be enabled/installed to get the load sharing equal between the cpu's - not exactly sure as it has been working fine until now.

    Can anyone provide some help on this??

    Thank you!

    PS Oh and i have checked the settings in the BIOS which havent changed the dual core is showing enabled which is the default.
