The drivers will not be loaded. Windows will have basic drivers for most of the devices. The actual drivers may be found on your driver disc. However later more up to date versions may be found from the Dell website. If you need driver specific help provide the hardware IDs for the video controller and wireless card (if you have a wireless card). These were the only variants in the system. Once I have these I can tell you precisely what to install. See here for instructions: [URL] 
Hello - This is my first experience here, I hope this is the correct place for my following enquiry... As the subject - I upgraded my 545 with the DELL upgrade kit moons ago.  I still have the 2 discs supplied by DELL. I would like to refresh my poor overloaded machine and would like to know if it is possible to do this by simply inserting the 2 discs and repeating the procedure as before, which was very successful and the machine has been very stable.  Of late it has slowed down and I would like to clean out the unwanteds. Naturally, on the premise that programmes will be lost during the procedure I shall save everything as required for later loading. I shall be pleased to hear if this is a practical solution to my turgid 545. Shall look forward to hearing words of wisdom from the knowledgeable members. Regards - Vicko       
INSPIRON 545 O/S has been upgraded from Vista to Win 7 - Can I refresh by 
simply running the two discs again to get a clean computer?
