my g5 is running like crap

I have the first edition g5 that came out
a dual 1.8 I upgraded to 3gigs of ram
Just like 6 months ago maybe less
I installed tiger do all the updates
and I am expecting this machone to run like a dream
It takes a long time to shut down if I am using a lot of programs
Any suggestions :
Oh and I just backed up my hard drive onto a seagate f/w hard drive
Is there a way to repair my mac by reinstalling tiger and holding down a key but making sure I dont lose all my software.
I just want it running nice again I dropped a large chunk of cash
for this machine and I love it
Please give me some suggestions
Adam

I have the same machine (dual 1.8) with 4gb RAM, I did the same thing... TIGER - and yes it was slow, and very glitchy!

I suggest eating humble pie and 'going Panther style, for a while' (poet - ha)!!!!
I did, it only takes a couple of days and you'll forget the widgets, spotlight etc.

Mac works fantastic now. Just wait until Apple have fixed the problem and it will be time for 10.5!!
:mac:

Did you do a clean install of Tiger? Clean installs will always give you the best results. There are occasional issues with upgrading where it does more harm than good

i dont know the terms so well
"clean install" what erase my hard drive
with all my apps than install tiger??
I dont know if I can replace everything if I erase it
Some apps werent totally "legal"
I cant lose em

well illegal programs can harm your computer and since they are illegal we can't help you with your problems here
