I bought a top of the line PC (3.2GHZ, 1GB ram 400Mhz, Nvidia 5900FX, Asus P4P800deluxe, 2x Maxtor 160GB 7200rpm 8Mb cache), and it was really good (it rocked!).
I turned it on and it was good. 30 sec to have winXP pro running.
I installed my Pinnacle PCTV pro, booted and it was not so good. over 1 minute to have WinXP loaded.
I deactivated PCTV, and it was good again. When i needed the card, i just had to activate it and could see TV.
Now win is slowed again. WHY, oh my lord, WHY?

any tip, Oh you mighty technicians, to help this poor user?
I tried witn TuneXP, system mechanic and others utilities, but no good
