Could someone please help identify a system bottleneck/configuration problem?

Ok, long winded post coming up, if you aren't up for this, please step out, and thanks for your time. Everyone else, here you go:

I am having problems with running games. I will lay out my entire specification in a moment, but first of all I shall describe the problem.
My system, as you will see, is fairly top range. It should run, in my opinion, ALL games at a fairly consistant 60 frames a second. I can accept occasional judders during heavy moments, but thats about it.
I run games with v-sync on, at a refresh rate of 60, as if I put the refresh rate any higher such as 85, the game goes jerky should the fps dip anything below 85. So it puts less demand on the video card to put it to 60, as it should be able to attain that height more easily. And if I disable v-sync, the fps at the demanding parts does not rise - the only benefit from disabling v-sync is that non-demanding areas, fps is higher.
ANYWAY!...
Basically, the fps is below 60 FAR too much, on TOO many things. Half Life for one, particularly during the heavy parts. Lots of game demos are juddery too - Evolva, FIFA 2001, Crimson Skies, plus many others, too many to mention.
OK - heres the FULL specs:

Win Me (Cache Network server, Disabled Sys restore, DMA auto enabled, swap file left to WIndows (Tried defining it myself, no difference), plus various other tweaks
P3 800e @ 992 with APLHA P£ 125S cooler
192 MB Generic PC 100 RAM
ABIT BE6 (Original) running at 124 FSB, "TH" BIOS, all Shadowing/caching disabled, and AGP aperture set to 128. Pallette snoop is disabled, and all other settings are optimised for peformance.
IBM Deskstar 13.3 GB HD 7200 RPM ATA 33 IDE
WD 1.9 GB slave drive IDE
Plug + Play 17" Monitor - max Resolution 1280x1024@75Hz
Soundblaster Live! value Win ME Drivers
Creative GeForce 2 GTS 32 MB (I try different drivers)
LT Win Modem (Does not affect performance, removed it to confirm this)
32X Samsung CD-ROM drive
3.5" Floppy

There you go - pretty much all the setings for HW I can come up with.
Is there any obvious problem I am missing?
Thanks for your time with this one.

 
Try lowering the AGP aperture to 16 or less, it shouldn't even be needed for gaming at all. Your slave drive may be slowing down your main drive. I have noticed in the Quake 3 time demo demo01 that it hesitates sometimes if DMA is not enabled, or it isn't fully installed. This should be similar to possible results from a slow drive. Because the drive is slave, it sets your transfer rate of your big drive to the same as your slower one. I use an IDE card do avoid this problem (DVD,CDRW,CD,and 2 HD's all on their own channel.) I don't have any problems burning disks this way either. Aren't you getting head aches from that low refresh rate?
