PSU
○ Strange noises from the back of the computer
○ When turned on, nothing happens
○ PC turns on for a couple of seconds, then turns off
○ In game or app, PC shuts off, displays a blue/black screen, & or freezing with buzzing noise from speakers

  Tips:
Make sure you are not maxing out the wattage. Keep PSU under 80-87% load
Back of PSU is cool or warm, fan(s) point outside of computer case
Look for a 5 year, full replacement warranty minimum, preferred Japanese capacitors
Keep it as dust free. Filters can be placed over the grill, filters reduce airflow 25%
Switch the power on the back off before unplugging PSU

CPU
○ PC won't get to the BIOS screen. PC powers on, but nothing happens
○ Renders slower or crashes while rendering.
○ Overclock is no longer stable
○ CPU is running hot, 80c, even with effective cooling

  Tips:
Check for bent motherboard pins before installing
Apply 1-2 rice grains worth of thermal paste
Do not touch backside of processor
Gently place in socket, line up arrow in corner
Overclock not recommended unless water cooled
Make sure voltage timings work with ram timings for stability, or set to auto

Motherboard
○ Random blue/black/white screens
○ Infinite boot loop
○ Can't get to bios screen, even after you pop in and out the battery
○ Windows reports a large array of errors
○ Reports a specific error. After changing hardware in question, integrity check says there are no issues, you still crash.
○ Can't render, play games, or other intensive apps without crashing
○ Motherboard shows visible burn damage on back or front when inspected
○ Capacitors are bulging
○ Weird burning smell from computer case
○ Hear a certain beep code upon restart
○ LED light on board is not it's normal color, usually green when on
○ Removing and re-seating cords has no affect
○ Bent connectors in CPU socket
○ Broken USB, SATA, or driver. Regardless of software roll backs, or updates

  Tips:
Make sure cords are in the right spots
Make sure ram, GPU are all the way in
Consult manual before putting together board
Check hardware compatibility with board
Make sure all proper drivers are installed
When in doubt, look up customer views online, looking for common errors

Speakers
○ Static noise, Visible Damage
○ No longer plays sound from both speakers, make sure video is in stereo
○ Most quality speakers last 5-10 years on low to medium decibels
○ Overheating, put speakers in a spot where they get hot
○ Near a radio tower produces weird sounds when idle
Won't turn on, Power Surge from lightning storm

  Tips:
Make sure video is in stereo
Accidentally set the audio on mute or low in settings
No drivers installed, Windows update like Skype can disable audio
Wrong port

GPU
○ Visual stutter, screen tearing
○ Graphical artifacts everywhere
○ Textures on 3d models look weird
○ Consistent crashes, blue screens, especially when playing games
○ Fan is louder than normal
○ Fails stability graphics test
○ Black screens

  Tips:
Get the latest driver, or second recent driver, always fresh install
Avoid beta drivers, or known problem updates, win10 can auto install bad drivers
Make sure all wires are plugged in, connected
Motherboard may not be able to handle SLI, or specific high powered cards

RAM
○ Fails diagnostic test
○ Slow loading of sites, games
○ Blue screen often error reporting a ram issue
○ White text flash before crashing
○ Random reboots
○ Corrupt files
○ Repeated failure to install software
○ Beeps at start up

  Tips:
Run Memtest, 4-8 hours preferred for 16gb, if any errors, remove stick(s)
Mismatch Ram
Incorrect RAM timings in bios, auto often works
Incompatible with motherboard can cause random crashes (rare, set to default)
Overclocking over 1600hz can damage ram. No major gain past 1866hz DDR3
only
Fans
○ Loud Noises
, fan moves slower causing more heat
○ LED light goes out
○ Reports fan error in Bios or diagnostic
○ Changed CPU thermal paste and heat is high
○ Fans are older than 10 years

  Tips:
Coolermaster, Noctura best performance, price and sound
Make sure the fan is facing the right direction, check arrows on plastic
If dying, open up sticker in center and put some WD-40 inside, replace ASAP
Dust out every 3-6 months or purchase dust filters, warning 25-35% less air flow
Avoid humid areas, near windows, vents
Make sure case has proper airflow

Disc Drive
○ Won't play certain color discs black, blue, clear
○ Makes loud noises, scratches disc (Stop running immediately)
○ Error when reading
○ Programs won't install from disc
○ Stops spinning when it should be spinning
○ Tray won't open, or opens violently
○ Won't power on

  Tips:
Solid state laser lifespan 5-10 years with daily to weekly usage
Write-able CDs 5-10 last years, DVDs 20-30 years
Movies, games on CDs last 25 years, DVD/Blu Ray 50-100 years
Audio glitches, hiccups in video is the first sign it's going

SSD
○ Stops working
○ Can't locate drive in bios
○ Monitoring Software kills the drive
○ Drive in poor area, overheats
○ Broken, bent ports
○ Power Surge

  Tips:
Do not Defrag SSD
Run drive in ACHI, not IDE

Flash Drives/Micro Flash
○ Very slow or won't read/write at all
○ Corrupt data
○ Disappearing data
○ Read error, write data error
○ Won't power on

  Tips:
Avoid static electricity
Right click in right corner of windows to safely disconnect device before removing it
Don't leave it plugged in all day, take it out when done
Transport it with more care than your wallet
Avoid water, humidity
Avoid extreme temperatures like leaving it in your car on a hot/warm day
10,000 writes life span, it's not as reliable as a portable HDD/SSD

Computer Case
○ Motherboard mounts aren't in place
○ Fans not working
○ Front ports like USB won't work
○ Front Switches, Power/Reset button stop working
○ Screws don't line up, fit
○ Rattling noises from loose metal
○ Some PCs won't power on if case door is open, the panel door connector breaks
○ Dust, power surge causes ports to short, smoke, catch fire, melt

  Tips:
Recommended Proper dust filters for 80-140mm fans $4-$6 each
Make sure everything fits
Make sure all wires from motherboard to computer tower are in the right ports
Make sure the case can handle the size of the motherboard, GPU, PSU, fans
Be wary of experimental case designs, can cause power surges, poor air cooling
Make sure fans are pointing in the right direction, proper airflow
Good cable management
When unplugging and re-plug wires, be careful of dust getting into ports

Viruses
○ Computer moves slow
○ Mouse stops moving, or starts moving on it's own
○ You lose access to your online accounts, keylogger

○ Inability to install anything
○ Inability to close program that isn't windows required
○ Loss of admin privileges
○ Shows up in a virus scan
○ Reappears after you delete it
○ No access to Regedit

  Tips:
Be wary of Win 10. Anything that has a keylogger, open door to hackers
Reinstalling windows from scratch if you are getting random errors, bloatware
If possible have 1 ssd for OS, and 1 hdd for everything else
Quarantine all you private data to an encrypted folder, or another separate drive,
meaningless if keylogger is present
Do not keep any exes of software installs
Always scan new exes with a virus scanner, check download source, file size
When you boot up your PC for the day see what files show up in windows search,
Google any suspicious processes

DDOS
○ Complete loss of internet
○ Router reveals a packet flood, or DDOS attack
○ Internet provider discovers a DDOS report in modem data
○ Server/Internet load will jump, disconnect, long periods of downtime

  Tips:
Make sure your ISP knows what to look for
Never share your IP address
Someone on social media is bragging about taking down your internet
ISP provider changes your IP address, unloading someone's problem onto you
ISP doesn't change your static IP, gives you a temporary fix
Sharing your connection with some other business or person who gets attacked
Never let your ISP sell you more Bandwidth or higher capacity internet
Skype and other games that reveal your IP on a stream make you vulnerable
