i just formatted my hard drive using the "hp restore plus" cd.
im now experiencing comsiderably slower performance than before i had formatted.windows startup is noticeably slow and perfomance has just decreased drastically on the whole
my machines a P4 2.6ghz, with two 512mb sticks of RAM and a 40gig drive
i suggest not using any HP or stuff CDs for reinstallation, because they come with whole bunch of other useless programs that might be causing the problem. try backing up ALL ur important docs somewhere and completely format ur O/S harddrive (leaving nothing on it, NOTHING) and do a clean windows installation.
