I have a NEC Ready 9701 system for those who may not know. It has a socket 7 motherboard for the old pentium I processors. Mine has a 150mhz processor in it. Recently I bought a 200mhz cpu off ebay. Upon installing, a few hours later on startup I got a 'Not enough memory to load registry, or the registry may be corrupted.' I had the jumper settings for 200mhz set correctly. I did a complete system restore. Would work alright for a little while, but then same problem. Digging around and taking the advice of techs and such I replaced the hard drive. That didn't solve the problem. It ran fine for a while(maybe a couple of hours) but eventually would crash or on restart would give me the same 'Not enough memory to load registry, or the registry may be corrupted' message again.So I replaced the stock 200w power supply with a 250w new power supply thinking old one was bad. Nope. Still same problem. So I replaced the newer 200mhz processor with the stock 150mhz processor that it came with and did a system restore. Problem did not return. Upon inspecting the CPU I bought off ebay I could see it was cracked on its back, and it was apparent some of its contacts and connections were broken. Its like someone took a hammer to it while it was still in the original motherboard because its ZIF pins were in excellent shape.

I contacted the seller and explained to him what happened. Figuring it was a fluke I had him just replace it with another 200mhz cpu instead of refunding the money. When I recieved the replacement 200mhz cpu I inspected it for obvious damage first. It showed no apparent signs like the first one except a little white chalky stuff on its back. However, a couple hours after installing this replacement cpu the exact same problem occured. I realize the guy could of gotten a bad batch of cpu's like from a wharehouse fire or something. But now that I have put 2 in with the same problem to me that means the likelihood of something wrong with my motherboard increases. Is it possible my motherboard has a defect that is causing it to freak out at the site of a 200mhz cpu?

I now have put my old 150mhz processor back in and have a couple hours ago, just finished the system restore and my puter is once again working fine.
