If you have a hard disk drive, it will be slow to boot up. If you have too little RAM, it may be slow because it is spending a lot of time swapping between the RAM and disk.
You need to look at the Task Manager to see if your CPU, RAM, or disk are operating near 100% utilization.
and please Also check your list of startup programs in your system. There may be unimportant programs that you can disable at startup.
If your video is sharing RAM with the operating system, you may be seeing memory starvation and need to add more RAM.
