You are right. It is an Acer .
I am running Windows XP Pro 5.1
Version 2002
Service Pack 3 (whatever this means)
It's an Acer Pentium R
CPU 3.0ghz
This problem came up about 2 months ago, and I think it coincided with a brief power failure that occurred due to a storm.
I use CA virus,anti spyware, firewall protection as well Microsoft virus, spyware and firewall protection.
I also have the free versions of Spybot and Adaware. These free versions have been on my computer for years.
Some friends suggested I restore my system back to a date prior to this problem happening. I am not sure what this would entail and how it would effect my existing programs and data.
I have all of my business info backed up on the flash drive as I am using my laptop (Acer Aspire) for my business. Initially, I was using the desk top Acer for my work stuff, backing up onto the flash drive and restoring the info onto my lap top. Therefore my desk top and lap top had the identical info. If I was traveling I could continue to do my work on the lap top and I would then transfer that data to my desk top. This way they were both always indentical.
I hope this gives you enough info to give me some help.
Thanks.
