如果是775 很大可能彎板 導致cpu座假焊 伴隨pcb板高溫 北橋高溫 cpu風扇高溫

感謝!
確實是775,最近修理的case和樓主狀況一樣,
滿板(asus p5ld2)灰塵,cpu濾波電容爆掉數顆,
剛過三年保固(2008/5購)



清掉灰塵換了電容仍舊無解,才以debug卡來檢驗


以前修理過的板子都會跳碼,唯獨這板子不跳,始終”00”,
查手冊ami bios代碼為
“已將程式碼複製到特定區域,準備將控制權交予int-19開機啟機載入程式(boot loader)

int-19
http://vitaly_filatov.tripod.com/ng/asm/asm_001.12.html
This interrupt is not a substitute for a Ctrl-Alt-
Del warm boot. This interrupt is the last action
performed by the Power-On Self Test (POST), which is
activated by Ctrl-Alt-Del. If a user program
attempts to execute this interrupt directly, the
machine may lock up.

To correctly reboot within an application program,
jump to FFFF:0h in memory. That is, set CS to FFFF
and IP to 0. This is the same process that occurs
when the machine is first powered on. Following
these steps will perform a "cold" boot. To perform a
"warm" boot using this method, first set the word at
location 0:472h to 1234h. This will simulate the
pressing of the Ctrl-Alt-Del.

A cold boot initializes all hardware, tests all
hardware, tests RAM, then calls INT 19h to load the
bootstrap loader. This process is performed when the
computer is turned on or a hardware reset button is
pressed.

A warm boot initializes and tests all hardware but
does not test RAM. It then calls INT 19h to load the
bootstrap loader. This process is performed when
Ctrl-Alt-Del is typed.

The sector read from the diskette will in turn read
in the rest of the operating system. A fixed disk
will read in a Partition Table, which will then read
in the correct operating system.

雖然換一塊二手板子是最簡便的方式,但想自己先嘗試一下,
在這種情況下,還有起死回生的可能性嗎?

走狗大的前兩張圖片, 看起來好像打完核戰一樣...

腳座下淋上免洗助焊劑 下方想辦法預熱 上面用貴桑桑熱風槍烘 會向煎魚吱吱作響
能治標開機使用 成功率有 但能用多久未知 那個是CPU 在這張主板不動作 不是找不到開機裝置

原來如此,等於沒有安裝cpu一樣,是否此意?
cpu、ram、vga、power經交叉測試後都證明ok,
我換了另一顆cpu來裝也是如此,
看來最有可能即hgame兄所提,
不過修理方法很另類,也許會嘗試一下,
有進展再予報告...

只是差在有上cpu風扇會轉啦 上775帶燈假負載 哪幾個腳位空焊就一清二楚
775 一定要用防彎背板 不然用久了 就會有這種通病出現
英呆爾 設計這啥鬼東西

上週我的775也是這樣
用到一半當機....
重開機後沒畫面沒B聲...
最後...顯卡重插又復活了Orz

不只775主機板會駝背....
顯卡太大片也會下垂,變形Orz

顯卡...8800GT大片那種...

保固內 顯卡彎版原廠推說人為不保固
顯卡高溫跟彎版 提早GPU假焊 就掛點啦
那就要玩玩 土炮 植球BGA GPU啦

走狗大,您想修的話,有點晚了....

看那幾張照片,應該是有損壞到核心元件了 , 沒意外的話 大概晶片組可能掛點了...

灰塵累積到那個程度,我猜有2-3年清都沒清理了,先是電容爆個幾棵,然後接著MOS跟著掛
然後供電的電壓或電流大增,接著打掛晶片組, 然後...... 你知道的.... :jolin:

去bbs.pigoo.com 去看看維修的實例,說不定我講錯了,能夠救回來也說不定...

祝順利!!

之前刷BIOS刷壞了
症狀就跟這很像
開機沒嗶聲也沒畫面
直接送回去刷BIOS免檢測
