想問我電腦這樣是壞什麼呢?

如果擔心是PCI-E插槽壞了，可以將顯示卡插到另外一個插槽裡，看看是否出現同樣情況，如是，顯示卡壞的可能性便很高。另外，可考慮執行視窗電腦診斷程式來知悉硬件問題：

Start Windows in diagnostic mode

1.Log in to the system with an administrator account.

2.Disable startup items, and restart Windows:
a.Choose Start > Run.
b.Type msconfig in the Open text box, and then press Enter.
c.On the General tab, click Diagnostic Startup.
d.On the Services tab, select any services that your product requires.
e.Click OK and choose Restart in the System Configuration dialog box.

Note: Upon restart, you are notified that the System Configuration Utility has changed the way that Windows starts up. Click OK, and when the System Configuration Utility appears, click Cancel.

If you want to troubleshoot video issues, continue with steps 3 -5:

3.Press the F8 key before Windows starts, when you see a message such as, "For Advanced Startup Options."

4.Select VGA Mode from the list of startup options.

5.In the Desktop dialog box, click OK to start Windows.


Restart Windows in Normal mode

1.Choose Start > Run, type msconfig, and click OK.

2.Choose Normal Startup on the General tab, click OK, and restart the computer.

On some computers, a function key (such as {F12}) can be pressed during bootup to enter the hardware diagnostic program for troubleshooting. There would be a message on boot up to show which key to press if this feature is available.

各位專家當前，我要說的，還是你的電腦平台太out了。壞是正常不過的事，若是要換這換那，不如索性重新購置新的，計起來仲化算，因為新的軟件或周邊設備，XP已不多支援(competible)。
算起來，XP已是10多年前的產品，現在Windoows已發展到它的第五代：Win XP - Vista - Win 7 - Win 8 -Win 10。

若果無對電腦既基本排解知識請唔好先判斷問題因由,應先由測試做起
測試唔需要額外買其他零件,只需要由零開始就可以
請預留充足時間測試
最好先戴手套,部分人身體比較特殊接觸電路有機會令硬件短路
1.中斷電源
2.重複禁開機制約一分鐘令主機放電

先打開機箱,將電腦所有部機拆開,
底版,聲卡(如有),顯卡,RAM,HARDDISK,CD/DVD機,CPU及風扇
首先將CPU及散熱風扇插上再通電,依個時候電腦會呈現響聲,根據你底版說明書黎睇番響聲是否正確(即係有CPU,但無RAM的響聲)
比如DELL既電腦就會響兩聲
如此做法順序測試以下硬件,每次測試都需要放電再進行插拔
注意,大部分配搭下開機都會有畫面
若無畫面即有機會係底板或火牛問題
CPU -> CPU+RAM -> CPU+RAM+DISPLAY -> 再加HDD -> 其他你既硬件

另外有啲牌子既響聲你可以參考下

冒犯講句,RAM有問題都可以引致黑畫面

Dispaly card bad contact or damaged!

1. Unplug the power cable of PC and take out the GTX560, clean the gold finger with a rubber (pencil eraser). Put it back & turn on to see it's work again or not

2. If above doesn't work means the GTX560 was defected & need to be replace...

我XP,也是沒法進入windows xp,是xp的档案壞了，現在microsoft在2014年4月巳廢除＼xp的支援,連系统还原也不能还原裝較新版windows七可能不能動




咁味迫到人換机才有生意做！


windows十現巳免費為windows 七及八upgrade,意味着取消windows vista的支援巳來臨
