Searching for possible solutions to a problem that I am having. I purchased an ACER Aspire One in Dec. 2008. I did the memory upgrade to 1.5 GB and it has been running great. However, this past weekend my aspire one began to display error messages. It begins to boot and reports a windows error. The "R" option will not repair the problem. When the R option is selected it shuts down. I try to boot to an external CD-ROM and it shuts down. I enter bios and try to set the boot options and it shuts down. I have removed the battery and the same problems occur.
