I should probably explain where I'm going with my suggestions here. First, the BIOS delay. I went through your manual a few times and although it does tell how to get into BIOS, it explains none of the settings there and then has the statement, "Please only modify the parameters if this is absolutely essential and if you are familiar with the configuration possibilities." I don't know how that is suppose to work if the settings aren't shown - so I'm ignoring that for now.
The suggestion about changing the CMOS battery (little watch battery on the motherboard) I put since you stated that BIOS is not doing the quick boot as you had set up. Often when BIOS settings aren't retained, it's because of that battery plus, it's a rather inexpensive "fix" (if it works). Never mind that though... I had a few epiphanies while looking through the manual.
1) Defrag and indexing... When was the last time Disk Defragmenter was run on your hard drive? Is it set up to run on a schedule? If it has been more than a few weeks, I'll suggest running it as a start (it may take a few hours to run). Are the contents of your hard drive "Indexed"? If not I'll suggest including that option (found under folder options)
2) When your graphics was changed, was a program such as Driver Sweeper run to remove all traces of previous graphics drivers?
3) Unless I'm missing something, you upgraded your operating system from Vista to Win 7 (your manual references Win Vista) - how did that upgrade go? Any issues then?
