Safari, Photoshop, others crash after upping ram to 1GB. A mystery. HELP...

Question

Has anyone heard of this problem: I've upgraded my 256mb ram to the max 1gb using two 512mb cards and have been having random crashes of Safari, Photoshop, Limewire and other larger programs. This has never happened before on this computer! The program just disappears and I get a error message that the program quit and asks if I want to send a notice to Apple or restart the program. It seems to be random and hard to reproduce. I even had the first two 512mb ram cards taken out and two different ones put in and the problem is still there.
The person who is a Powerbook expert who put the cards in has never seen this problem before and can't seem to figure it out either.
Please help me with this. Maybe the 500mhz G3 Powerbook Pismo can't handle 1GB? We're really stumped on this one. I really need some help. Thanks.
Steve

Cornelius and JPL,
Thanks for your help but I just can't figure it out. Maybe the Pismo 500 really can't handle the extra memory. But somehow that doesn't seem right. I tried all the fixes and looked at the websites, Dr. Smoke etc., that were suggested but nothing helped.
I can't figure out how to read the ram card to make sure it is the exactly right kind but I got it from a reliable dealer who only deals with Powerbooks. The sticker on the chip reads:
Samsung
KOREA 0215
PC133S - 333 - 542
M464S6453CKS - L7A
And printed on the chip it says:
SAMSUNG 214
K4S510832C-KL75
Whatever.
I brought the cards back to the dealer once already and got new ones and had the same problem with aps quitting.
I tried running the disk permissions program, removed bad fonts, completely zero'd my machine and put os 10.3 back on to see if maybe it was 10.4 that it wouldn't work with. I ran the Apple Hardware test. No luck!
I then tried one old 128mb card in the bottom and one of the new 512mb cards on top and same problem.
Finally tonight I just left in the one original 128mb card and there is no problem at all!
So I guess it's the ram cards, right?
But the question remains: Why is it quitting aps with 1GB memory installed?
Oh well, I'll check and see if the cards are maybe not exactly the right ones but I think the fellow I'm working with knows his stuff. He's been really good about helping me so the next step, he said, was to take back the second set of 512mb cards and get actual "Apple cards" (whatever that means) and see if they work. Does that sound good?
Thanks for your help and if you have any additional comments I would love to hear 'em.
Steve
