Recently I installed Windows 7 ultimate 32bit on my laptop Acer Asprire 5100 (model 2 years old), with AMD Turion 2,2Ghz, 120GB HDD, ATI x1100, 1,5GB RAM (graphic card uses 256MB from that 1,5GB), along with some other programs Firefox, Office, Nero...also I've installed TP Link wireless router to my cable internet modem, and set WEP secured network (10 digit code). After that I installed Opera and Flash player, and USB wireless mouse Logitec.
Everything worked good for 3 days, and suddenly, when I start the system, CPU usage is from 75 to 100% all the time. When I go to task manager, I don't see processes that are using CPU. When I installed process manager, I see that DPCs are using around 50% of CPU. It takes normal time to start windows, but shutting down thakes around 10 minutes.
The funny thing is that my touchpad is not working nor my keyboard (they work, but very strange - only few keys work, and touchpad glithces) on laptop, but I can use wireless mouse normaly and start programs (Total Commader, whatch videos...)
When I start windows in safe mode, everything is ok.
I used system restore on day of instalation, but same system presists.
Anyone have a clue?

mrzelo me je da pisem ponovo na srpskom :)
