I had a home built computer that worked fine for a couple years then all of a sudden I began receiving error messages and programs (e.g. Google Chrome) would crash. This lead me to believe files in the operating system were getting corrupt some how. I was dual booting Windows 7 and Ubuntu. The errors / crashes affected both OS. Originally I thought the hard drive was failing, so I replaced it and did a fresh install of Windows 7 and Ubuntu. However, after a few days the same problems happened again. Since the computer was a couple years old, I decided to build the whole thing, only use the same case. I bought parts on Newegg.com and assembled a new system including Motherboard, Processor, Hard Drive, RAM, DVD and power supply. The only component I reused was the case. I also bought a new surge protector. Everything worked fine with the new system for a couple weeks but then I began noticing the same error messages and applications crashing. So, I ran memtest and it showed I had memory errors. I had installed 2 different brands of RAM in the system (four 2-gig modules), so I removed one brand and ran memtest again. Same result...memory errors. So I removed that brand of RAM and installed the other and ran memtest again. Same result...memory errors.
So now my question.
Since I totally rebuilt the system, except for the case, and have the same problem could it be something else? I would think it is unlikely that two different brands of new RAM would be bad. I have an external backup drive I periodically use. Could that cause the problem? The only other things connected to my system is the router, printer, my camera cable and headset. I would not think these would cause a system to go bad.
Any suggestions is appreciated.
