Folks: I have a 6 year old Dell 2350, it runs Windows XP SP2. A few years ago, I replaced a bad memory stick in on advice of a computer Guy. I had an excel spreadsheet that suddenly got scrambled while I was working on it. The new Memory cured the problem. Now, occasionaly on shut down I get a brief msg on the screen that says "it cannot write to memory xxsx93938, or some such number. Also, for no apparent reason at times, the desk top repaints itself, goes blank then all the icons seem to be like when it boots up before it is done, then it is normal for a while. i have cleaned out all the dust, made sure the fan is not blocked and running ok. Nothing else seems to be wrong, with the exception of s slow boot up to my settings(probably due to a lot going on and it is old.). I have not been able to connect this occurence with what I am doing at the time. Any ideas, or is it just old and wants to die? Tx Mike M
