MORE kernel panics with 10.4.5

Question

ok so i posted that i had kernel panics after updating to 10.4.1 etc. and after i installed the newest security update to 10.4.5 the kernel panics stopped...for half a month. now all of a sudden as april hits my screen keeps having little mini freezes(the curser freezes..then moves again after like 5 seconds..then another few seconds later my screen works again. grr. well apparently i also had "graphics card" panics the past 2 days. now as i mentioned i updated the security update and it fixed the driver issues that were mentioned as a problem with nvidia geforce2 graphics cards. now NOTHING has been changed on my comp and the panics are listing graphics cards as the i had before(listed below)
now as i type this i have had like 5 freeze ups. i have tried running disk utility and fixed permissions. and after i restarted after kp my screen was ALL messed up and showing lines and much stuff itwouldnt show icons unless i moused over them but my desktop pic wasnt complete either

hey thanks for your words of wisdom i will work thru to the best of my ability. my post wasnt complete as i would have liked it as my comp was driving me beyond insane so i just posted and quit to "walk away lest i KILL the machine". so i will add to it now. had another kp same ostensible reason. however after i restarted this morning the machine has been acting normal. so at least that allows me to go thru and try some trouble shooting things.
i have tech tool pro 4.1.1 which i believe is the newest update or at least as new as needed for compatibility and such. i ran it with no reported issues. i also have disk warrior(latest update) and ran that with no reported issues(tho i have heard that the new tech tool is superior). i DO have an external drive(maxtor one touchII). which before a driver upgrade was a source of issue with my system. but that was resolved easily. THEN i updated to the newest system point updates(10.4.1-10.4.4) and had problems with KP again IMMEDIATELY. listing grapics card as problem. well as update 10.4.5 listed nvidia graphics card driver updates in its list of features i managed(with much trouble) to update. still issues till i installed the security update then everything was honkydorey for about 20 days or so then all of a sudden graphics card issues. i WAS wondering if driver support problems could have damaged the card?
also however i remembered that i hadnt updated the system on my external(which i primarily use for storage and backup but my father installed Tiger on) OH says I that is still using the system that conflicts with the graphics card i will upgrade that...well i cant seem to do so. when i try to install the newest updates(one at a time 10.4.1-10.4.5) onto that system it starts to check the configurations and then suddenly says the installation failed/had errors and to try again. i assume that the packages are ok as they are the ones i borrowed from my father (since i was unable to download myself due to graphics card driver issues) to update my main comp and that worked fine.
i have at this point disconnected my external drive(temporarrily) as i suspect this contributes to the problem(not sure yet) but i would like to fix the problem not just avoid it.
i wouldnt have any problem wiping the system off of my external and just using it as storage again but i am not sure how to safely do that without losing my other files (i have over 19thousand music files(all legally bought tunes) stored there from loading my cd collection onto my comp. and not enuf room on my main comp to store them of course) i wonder if perhaps creating a file OUTSIDE they system for the music files should keep them safe? also how do i UNINSTALL a system? i have never done such a thing. or is there a better solution to update the system on my external?
thank you in advance for any advice you may have for me. and again thanks for the advice listed in the previous posts...i will definitly delve further into that.
