Probably this kind of question has been asked way too often, but as of yet I have not found a satisfying solution; please accept my apologies if I am wasting your time.
Introduction
As Windows gets slow over the course of years, especially when used by ignorant people who fill it up with toolbars and fake "optimization" software, I decided to reinstall it in order to get rid of these issues.
The Windows version that had been installed beforehand was probably Windows 7 x64 Home Edition. Since I was unable to find the OEM DVD's I used another copy of Windows, Windows 7 x64 Professional Edition, which I assumed not to be a problem.
The problem
However, the installation of Windows 7 took multiple hours, which should not be the case. The selection menus responded extremely slow. It could take up to a minute before a drop-down menu appeared after clicking it. When Windows was finally installed, everything was excruciatingly slow and unresponsive. Internet Explorer even failed to launch. It took minutes to get into the control panel.
Additional Information
- The computer has been produced by Medion.
- CPU: Intel(R) Core(TM) i7 CPU 870 @ 2.93 GHz (eight cores) (CPU family 6, model 30)
- 8 GiB RAM memory, (4 x 2 GiB, DIMM SDRAM Synchronous)
Motherboard: MS-7616 (Medion)
When I boot from a Debian-like live USB-drive, everything runs smoothly wihout any trouble (and no, no matter how much I like Linux, installing Linux is not a viable option since the purpose of the computer is gaming).
- Hard disk operations are as fast as I expect them to be under Linux, which led me to believe that the problem is a software issue.
Questions
- Could this be a drivers issue? If so, how could I solve it? I thought I might solve the problem by installing the appropriate chip set etc. drivers from the internet (since I lost the OEM disks), but I do not know how, for IE does not start.
- Could it be a BIOS/CMOS issue?
- Is it a problem that I cannot find the OEM disks?
- Could corruption of the installation DVD cause the issue?
Thanks in advance for your support.
Update 1/1/14:
- Using gnome-disk-utility (palimpsest) while running a Linux live image, I found no disk errors.
- When I copy files from the hard disk to a flash-drive under Linux, I experience no problems, reading performance is normal.
- I transferred the installation executable of slimdrivers to the desktop and ran it under Windows, in safe mode, with administrator privileges. Installation failed, a message told me that Windows Installer did not work properly or was not installed.
- Interestingly, no matter what I do under Windows, Task Manager says the PC uses approximately 0 to 1 % of the CPU capacity and only 10% of the RAM (822 MB).
Update 1/2/14:
- I ran "chkdsk /r C:", it found no errors.
