|---|---|---|---|---|---|
| True or false, symptoms of a failed or failing CPU include: PC will not boot. PC boots, but the operating system fails to load. PC has POST parity problems with a number of devices. PC locks up shortly after startup? | True
🗑
|
||||
| True or false, PC locks up shortly after startup. This symptom is possibly a cooling/heating problem? | True
🗑
|
||||
| True or false, you suspect the PC is overheating because it locks up shortly after starting.Check for this problem by shutting down, letting the system cool off, and restarting the computer to verify whether the problem repeats itself? | True
🗑
|
||||
| True or false, If overheating seems to be the problem, check the heatsink and fan for placement and condition? | True
🗑
|
||||
| True or false, If overheating seems to be the problem, verify that thermal paste or a thermal pad has been used between the processor and the heat sink? | True
🗑
|
||||
| True or false, If overheating seems to be the problem, verify that the heatsink is firmly attached to the CPU? | True
🗑
|
||||
| True or false, If overheating seems to be the problem, verify that the CPU is properly seated in its socket? | True
🗑
|
||||
| True or false, If overheating seems to be the problem, verify that system case fans are working and that the case and expansion slots are in place? | True
🗑
|
||||
| True or false, If overheating seems to be the problem, and if the CPU is an older Pentium without a heat sink or fan, add one? | True
🗑
|
||||
| True or false, if the computer is not overheating but locks up shortly after starting, the problem could be the clock jumpers on the motherboard or system timers (in BIOS) are set incorrectly for the processor? | True
🗑
|
||||
| True or false, if the PC sounds a POST beep code indicating a CPU fault upon boot-up, verify that the CPU is receiving sufficient power by checking the power outputs? | True
🗑
|
||||
| True or false, if the PC sounds a POST beep code indicating a CPU fault upon boot-up, verify that the CPU is receiving sufficient power by checking the power outputs. If these are good, replace the CPU? | True
🗑
|
||||
| True or false, if the PC sounds a POST beep code indicating a CPU fault upon boot-up, verify that the CPU is receiving sufficient power by checking the power outputs. If these are good, replace the CPU. If the fault remains, the motherboard is faulty? | True
🗑
|
||||
| True or false, if the PC crashes on startup or when running a software application or certain group of applications, run repetitive test using diagnostic software? | True
🗑
|
||||
| True or false, if the PC crashes on startup or when running a software application or certain group of applications, after replacing a seemingly faulty CPU, then run similar tests on the motherboard and chipset? | True
🗑
|
||||
| True or false, if the PC crashes on startup or when running a software application or certain group of applications, check for a corrupt file in the software? | True
🗑
|
||||
| True or false, the computer boots but the processor is running at less than its rated speed, check for incorrectly set motherboard settings or edit the CMOS to set the appropriate CPU speed? | True
🗑
|
||||
| True or false, If you cannot set the correct speed in the CMOS settings, try updating the BIOS with the latest version? | True
🗑
