In your opinion, what are the top 5 PC problems in the categories : hardware, software, internet , and in network (5 for each category) that I should be aware of considering that I have a computer.    I only know BSOD and PC always reboots.

I searched it on the NET but they have different answers that I can't organize.

Here is a list that may help us get started:

No... Its not homework, as a beginner, I would like to know at least how to solve 5 of the frequent problems in each category, so that if ever someone asks me I would be very much aware about it

I agree with Allan that just hanging out here you will pick up alot of general PC knowledge...and feel free to ask if something doesn't make sense...

In my own opinion and from searching around on Google
Hardware:

• Hard drive failure
• Overheating due to failing fans or thermal compound incorrectly applied
• Faulty power supply
• Cables and connections not seated properly, motherboard standoffs not in place
• Problems with expansion cards

Software:

• Backup of user data
• Viruses and malware and incorrectly config'ed firewall
• Try not to have too many unnecessary programs installed
• Clear your temp and cache files
• Defragment your hard drive frequently

Internet(Although there's not really much you can do to fix problems on the client side):

• Can't access any websites due to problem with local configuration
• Server is offline
• Banned/Access Limit by ISP

Network:

• Out of WiFi signal range
• Router not configured properly(Includes DHCP errors, IP address conflicts, port forwarding, subnet issues, etc.)
• Connections dropping unexpectedly
• Problems with sharing that cause network devices to not be able to "see" each other
• Insecure network(such as open ports, firewall not configured properly, guest and AP isolation not configured properly, etc.)

Speaking as someone who is not a beginner, but by no means an expert, you could write volumes of books on each category.

You could attempt to find questions on this forum, that you do not know the answer to and research it.

Pick a topic and read a book on it. There will always be troubleshooting techniques relating to most subjects.

Also, as i've done plenty of college work in the past. Your original question is written in the same vein as homework questions. Usually, they are quite easy to spot............
