Good Day PCBuild Listers, I have a problem and I'm hoping some of you can offer some suggestions.  I recently built a system for my bro-in-law, it's running with a Chaintech 7AIA5 KT133A motherboard with 1.3ghz duron processor, 512mb of ram, 20gb maxtor drive, 128mb radeon card, dvd, cd-rw, etc.  Pretty decent system.  We were originally running Win98 (first edition not SE) on the system and we upgraded to WinXP, we kept both and we dual boot between 98 & xp, we have 98 running on a 4gb partition, xp gets the remaining 16gb (both partitions are fat32).  We can run Windows 98 indefinitely without any problems, however with winxp we run into system freeze up problems.  It's not the install of xp because we've done it a few times just to test it out (ie. removed win98 & formatted the entire hd,
 and installed xp by itself).  XP either hangs during boot up or when it does run, after @ 20-30min of operation, they system freezes up completely - we can't ctrl-alt-del to see what service or software failed or anything - the system is just frozen and requires us power off/on the machine and repeat the process. Also xp's chkdsk tends to report a truckload of problems during most (not all) boot up's. We also find that this occurs more frequently when we use the internet (high speed dsl).  I've run scandisk several times to no avail, and Norton Utilities can't find any problems.  Ultimately we returned to a dual boot config just so that we could run win98 incase winxp became totally useless on any given day.  We're running with all the updated drivers for this system.  Why would Windows 98 run flawlessly and XP have all these problems?  We purchased a new WD 40gb drive a few months ago and installed xp on it (we also tried win2k) but we get the same issues - so it can't
be a drive issue from what I can tell. I've also tried switching the ide cables and placing the hd on the secondary master instead of the primary master since the motherboard provides for 2 ide connections - I can't say for sure that this improves the situation - maybe a little but this isn't reliable enough to say we've fixed the problems because we still experience the system freeze up's in winxp.  Anybody else experience similar problems like this?  Is it possible that it's a motherboard problem?  I've run SiSoft's Sandra diagnostic and it hasn't reported anything (is there better more thorough diag software out there?)  We would really like to run WinXP since MS has ended support for Win98 and also since XP is the newest OS available we would like to use it.  I am interested in any comments/suggestions available.  Thanks for your help.....uncle rob,wpg.
