How to speed up Windows 8 on Samsung laptop?

Solution 1:

One of my friends also has a Samsung Windows 8 laptop, and disabling the Samsung service "IntelliMemory" service solved all of his issues.

1. Run services.msc
2. Locate "IntelliMemory"
3. Right Click -> Properties
4. Startup Type -> Disabled
5. Click "Stop"
6. Click "OK"
7. Reboot

IntelliMemory is a product which is installed by default on Samsung Windows 8 laptops. Samsung pre-loads IntelliMemory on most of their Windows computers, and it's the first thing to remove from a machine with an SSD drive. It can speed up slower conventional spinning hard disks by caching lots of stuff to RAM (memory), but when you have an SSD this isn't helpful and it tends to hog all the RAM. It can be safely removed from a system using an SSD drive.

Solution 2:

As suggested by others, this would seem to be a hardware fault. We are dealing with slow Windows 7 startup/shutdown in an enterprise setting at the moment but even we are only dealing with 8 minutes.

If it were a few minutes delay, I'd suggest a network issue but given the extreme time, I would think that it is a Hard Disk fault.
