I bought a used PC with 128 MB (4 chips at 32 MB each) of RAM. I would like to install all 4 chips in my PC. The chips all fit into the 4 available slots, but when I boot up, they are apparently unrecognized, and all I get is a blinking power light on the monitor. Do I have to do anything to make the chips work. I don't remember doing anything before. When I put the old chips (2 - 8 MB and 2- 16 MB) back into the slots, they are recognized no problem. Any advice appreciated Thanks, Gary Do you want to signoff PCBUILD or just change to Digest mode - visit our web site: http://nospin.com/pc/pcbuild.html
