Windows cannot format the partition it is currently running from (usually the C: drive) because the operating system files are in active use. To format C:, one must boot from external media. Attempting to do so within the GUI will result in an error message stating the drive is in use.

WinRAR is a file archiver utility that has its own file browser. It can display files regardless of Windows 'Hidden' attributes or registry-based restrictions on 'Folder Options'. Internet Explorer and File Explorer rely on system settings, and WinZip is less commonly used for this specific workaround.

An active virus typically shows high CPU usage as it runs malicious processes in the background. Legitimate viruses usually run under the user's context (your username) rather than the System process, though sophisticated malware can disguise itself. Memory consumption is not a definitive indicator as legitimate programs can also use high memory. Task Manager's Processes tab helps identify suspicious processes running under your user account with unusual CPU usage.

When a computer doesn't switch on at all, the issue is typically with power delivery or the motherboard. SMPS (Switched Mode Power Supply) provides power to all components, and if it fails, nothing receives power. A faulty motherboard can also prevent the system from starting. Hard disk and RAM issues usually allow the computer to power on but fail to boot properly.

When a system starts but shows no display, RAM or motherboard issues are most likely. RAM problems prevent the system from completing POST, while motherboard failures can affect the GPU or display output. Storage devices like CD ROM and hard disk don't impact the display signal.

Junk or grainy display with irregular lines is typically caused by faulty or loose RAM. The RAM sends video data to the display; when corrupted, it produces distorted visual output. Hard disk, processor, or operating system issues would cause different symptoms like boot failures or system crashes, not display corruption.

Venkatraman Ramakrishnan, an Indian-born British-American structural biologist, won the 2009 Nobel Prize in Chemistry along with Thomas Steitz and Ada Yonath. They were honored for their studies of the structure and function of the ribosome. Ramakrishnan's work focused on determining the atomic structure of the ribosome.

Barack H. Obama was awarded the 2009 Nobel Peace Prize 'for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples.' The award was announced in October 2009, early in his presidency, and was somewhat controversial as he had not yet completed major peace initiatives.

Amartya Sen, the Indian economist and philosopher, won the 1998 Nobel Prize in Economics (officially the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel). He was honored for his contributions to welfare economics, including his work on social choice theory, poverty measurement, and human development approach.

Nelson Mandela and F.W. de Klerk were jointly awarded the Nobel Peace Prize in 1993 for their work in peacefully negotiating the end of apartheid in South Africa. This was a pivotal moment in South Africa's transition to democracy.
