My in-laws have a two-year old Dell P4 machine running XP Pro which came with 128 MB of RAM. As you can imagine, it wasn't the fastest machine. I added 256 MB of RAM a few months ago and WHAM! The system is blazing fast. Multiple programs open quickly and run smoothly. Everything is copacetic. A couple of weeks ago they buy a Dell laptop with wireless capability and a Belkin wireless router. I set those up and everything is fine and dandy. A few days ago the desktop computer starts acting like it's running in slow motion. Try to open a program and the hourglass symbol comes up for what seems like an eternity before the program actually opens. Run antivirus program and nothing found. When using Internet Explorer, going to a different web site drags too (they have Road Runner cable modem). I empty the Temp files and cookies, but no change. I try to install Spybot but halfway through the scan the machine freezes up and I have to reboot. This happens several times. So I uninstall Spybot and install Ad-Aware, which finds a couple of hundred files that need to be deleted, which I do. I reboot the machine expecting Shangri-La. No such luck. Machine seems a tad faster but still is at strolling pace when it used to scream after I first added the additional RAM. So I call Dell Tech Support. They have me run msconfig and uncheck all the startup items except for a few key items like systray and antivirus stuff. This helps but does not bring the system running anything close to the speed it was until recently. So the Dell Tech tells me I have to back everything up, reformat the hard drive, and reinstall everything. Any of you techies out there have any other suggestions short of reformatting the hard drive? I thought the Dell Tech didn't do enough diagnostics, but of course I could be wrong. It just trips me out that a machine that was running so well would suddenly make such a dramatic slowdown and the only option available is to reformat the hard drive. Thanks. p.s. laptop runs great. p.s.s. Defragmenter says the hard drive does not need to be defragmented at this time.
