Start here when your computer is acting up and you are not sure what is causing the problem. These guides help you narrow the issue down before you buy parts or pay for repair.
Choose your problem
PC turns on but no display
Use this when fans spin or lights turn on, but nothing shows on the monitor.
Power supply problems
Use this when the PC randomly shuts off, reboots, clicks, smells hot, or acts unstable under load.
Blue screen crashes
Use this when Windows crashes with a BSOD and you need to read the minidump file.
Laptop overheating
Use this when a laptop gets hot, throttles, shuts down, or runs the fans constantly.
RAM problems
Use this when the PC has random crashes, failed boots, memory errors, or instability.
Not sure where to start?
If the computer powers on but does not behave normally, start with the no-display guide or PSU guide first. Those two guides cover many of the most common hardware failure symptoms.
