I have Acronis True Image Version 9.0 and it causes my CPU to spike to 100% and it freezes my computer. It is impossible to do any other work as this is doing a full backup so I do it at night. However, today I decided to do a new full install and I watched the CPU. Finally after 2.5 hrs for an 80gb hard drive to back up about 50gb it began to verify the backup and the CPU would drop at times a bit, but the freezing was still evident. Afrer 4.5 hrs it was finished and the freeze was gone as the CPU dropped. I had the same problem with McAfee anti virus with a virus scan and was advised to get rid of that system resource hog which I did yesterday and installed a Free AVG Anti virus Free edition. That would also spike the CPU to 100% but not all the time like McAfee did. But something in Acronis is causing such a system resource grip on the CPU. I am running a 4 year old Compaq 5430US Pentium 4, 1.8gHZ 1 gb RAM Windows XP SP2. The 80gb hard drive is half full. Can I anybody figure this out as to what to do?
