Hey Tiggytam. Xp is good, I have run it for about 15 months now. Just a couple of suggestions: Microsoft recommend a minimum of 128 Mb of RAM, I run 256, but friends of mine reckon 512 is spot on.....Be careful with antivirus software as some older a/virus programs conflict a little with XP, and if you are on a dial-up connection, make sure you have a modem that is XP compliant. I don't, and often find I have to reboot so the Operating System will recognise the modem is actually there. Also, if you go XP, make sure you get a legit copy - unless you know someone technically savvy, any upgrades you download from Microsoft will wreak havoc with your PC. I would personally recommend finding a friend or rellie who is tech savvy, saving all th docs/emails etc that you need, formatting your hard drive and starting from scratch. Sounds scary, but ME & 2000 are pretty stable, no need to spend the money on XP unless you really want it. Most times I have found that glitches on your PC happen when you install games and 3rd party software. If you reformat, partition your Hard Drive so any games or 3rd party software can go in a different area to your Operating Systems. If you have any questions, feel free to post a message on the board. Cheers, Smoo.
