Since I had this 256 mb of ram laying around I thought that I would use it. During previous experimenting it told me that it could only see HALF of it. I thought it was better then the whole stick being bad. So I stuck it in a machine to give it a little more power. Know when I BOOT it up it wont load the os, it was working would this be at fault? I had to already replace the video card to get it to work which is probably still good.Why don't you just take the RAM out and see if the machine works correctly? I think you said that the RAM was installed as an extra memory boost.It will boot an I dont like pulling stuff out if I dont have too. Seems like I will just windered if I couldnt have used it.Well the only way to tell if the ram is the culprit is to pull it out and try it. You could always try a free RAM testing program. They usualy boot from a floppy disk or pen drive. They used to be quite common but I can't find any now but maybe another member knows of some.MemTest...Well it wasnt seeing the Drive in the BIOS an I dont have any spares at the time, sorry I'm fairly busy tring to do other things an just need some dumb help now an again but this was a working a working drive. Whatever.I thought you were TALKING about ram?I was, I said it couldnt boot the OS which made me think the ram was the problem cause it did have problems. Turned out its the drive.Okay so I checked the IDE cable an its not the problem ehter I tried two drives it SEES the one an the other isnt seen.Well when you start a topic about ram and suddenly switch to a hard drive problem, it is a little hard to keep up.I didnt want to start a new topic an it turned out that it wasnt the RAM at fault
