我部電腦成日唔知點解自己熄機,希望高手們幫幫忙.

1. Replace your monitor with another one and try. It doesn't have to be new and something special, just a working one will be fine. Run it for a few hours. If the PC is normal, your monitor needs replacement. If it's still the same, replace the video card with a similar one for trial. If normal, replace your video card. If all fail, see below.

2. Try to correct overheating. Disconnect power. Open the tower and clean everything inside, including fans (and blades), motherboard, RAM & video card slots (remove, clean then reseat), heat sink fins and anything dusty. A small soft clean paint brush will do the job. Repeat this every 6 months anyway. You'll be amazed what it can do to your PC. If problem still exists, replace the thermal compound between your heat sink and CPU. Old and brittle compound can cause overheating on your CPU and Windows/motherboard will shut it down when it exceeds a certain temperature.

3. Tidy up your cables inside the PC to allow better air flow. Make sure your have a least 2 fans for the tower. One for drawing while the second one's for blowing air out. This is the best ventilation you can get.

可能會過熱...過左安全指標就自動熄機...我試過...
唔關MON事...MON係獨立既...主機唔同MON既
你試下裸機(唔要機箱)或者拆左個側板佢
唔想咁煩可以用軟件睇溫度e.g:HWMonitor,CPUZ,GPUZ等
又或者會係你主機板問題...太多問題...唔可以一句講晒

magic-pro 板口碑唔系太好
你開EVEREST Check 下你有冇野過熱 最好FULL LOAD一下 CPU RAM
你隻咩牛黎?幾多Watt ?

會唔會你DISPLAYCARD有問題?

佢熄機既時間係唔係都差唔多呀?
