Cisco 2611 router interface issues

I am having a strange issue with my Cisco 2611 series router. I bought this router along with some other Cisco equipment to get CCNA certification. I thought what better way off than learn what I am doing is to put into practice in my apartment so I can see things happen in real time. The router worked all well and good until I ordered a memory upgrade kit off ebay to max it out both in flash and ram. I also upgraded the IOS from 12.2 something to 12.3(17b) which came in my router kit. Ever since then the routers Ethernet interfaces are experiencing strange issues like they are unresponsive but there is no crash log in the flash or when you do show ver. If I try to ping from the router depending on what interface is having issues I will usually get a 20% success rate on the ping. A reload will sometimes fix the problem but every once and a while I have to erase the nvram and copy my config back to the router to get the dhcp to pull from my cable modem. It does this every 12-20 hours, before the memory upgrade the router ran for a week without problems. I am hoping someone here has some insight on what could be going on. I can post any outputs that you like. I have about had it with the upgraded memory and flash and I am thinking about putting the old stuff back in, but I would prefer to be able to use the better feature sets when working with it.

Thank you in advance. bhawkins
