>However, I think I may have found something which could have been in effect. I have been running with keyboard and mouse wireless. I never had any problem with the mouse. However, the keyboard started to give me problems a while ago, basically, within a similar timeframe as when I started to observe latency. Basically, this is one reason that led me to try to find a new wireless keyboard. For now, however, I am still using the one I have been using for a while. Thus, the behavior is as follow. After a while, or sometimes right at the boot sequence, the keyboard would work so bad that keys would remain stuck, replicating infinite keys on the screen, very bad delays. When this happens, it appears to affect the entire performance of the PC.

>This is what I cannot understand. Can a wireless bluetooth keyboard be really causing latencies like that at the PC level in general?

>Today, I have been using my laptop from another location. I use the keyboard directly from the laptop. I still use the wireless mouse. There is no problem. As for the performance itself, there is no problem. My only assumption is that the keyboard I use at home is getting really bad and it might cause all those problems. Can this really be related?

I have to ask: have you tried changing the batteries on your wireless keyboard?
