I started off with a system with the following specifications:

CPU: Intel Core 2 Duo E6300 1.86GHz
Mobo: MSI 975X Platinum
RAM: Corsair 2x1GB RAM DDR2-800
Vid Card: Gigabyte GV-NX76T256D-RH 7600GT 256MB GDDR3
PSU: Corsair HX Series CMPSU-520HX 520W Power Supply
OS: Win XP SP3

For the most part the system ran fine and I didn't have any major problems, but I use it as a video server (PS3 Media Server) and wanted to improve transcoding for 1080 source material. It worked ok for watching, but fast forward or rewind wouldn't work well. I also wanted to improve video encoding times when converting .flv files to other formats. I purchased the following equipment:

CPU: AMD|FX8320 AM3+ 3.5GHz
Mobo: ASROCK 990FX Extreme4
Vid Card: Same
PSU: Same
OS: Same

In the past I have used repair installations when changing motherboards and I have never had a problem. However this time I made an Acronis image of the HDD as backup and tried this technique
Which is basically manually removing all drivers that are specific to the old motherboard and CPU, rebooting with the new hardware, then re-installing the new drivers. With a little trial and error and a tool that removes non-present devices from Device Manager I was able to get it to boot up fine and install the new drivers. At first I thought everything was fine but it just seemed that the computer would hang while doing things. I then had task manager running while using the computer and the CPU load would be almost 0% during these hangs and there was no significant HDD access. It was just sitting there. I notice this type of behavior the most while using the web browser, or installing, or uninstalling software. Also, my internet speed is about 15M. But when I go to any site to test it is reported to be 50-70M now (regardless of browser). The upload speed is still reported properly. Another example is that I was downloading (not installing yet) updates from windows updates and I tried to play an MP3 file and it was really choppy. So I tried a repair installation of Windows XP and it made no difference. I have looked through Device Manager (even looking at hidden devices and non-present devices) and I have found no problems at all. I decided to install a benchmark tool (PassMark) and the CPU test was less than 2000 and it should be over 8000. Actually the memory and graphics card benchmarks were much worse as well. Only the HDD performance was near what it was suppose to be. I have also done a clean install on another HDD and while I didn't run benchmark tests, it didn't seem any better. Could this be a faulty mother board or CPU?

It ended up being CPU temp. It was 67C because the fan had stopped working. The temps are now 17C and things are running much better.
