Hi,

What is most possible problem if there is no post screen, but the power led, hdd led is on and the fans is not running ?

In most case, if I change the AGP card with PCI then I can see the post screen. But this time, not only blank screen, the keyboard just not functioning as well.

The story goes like this, I just bought a Athlon XP1800+, install it on Gygabyte GA-7DX with Original AMD HSF, Geforce 4 MX-440. Working fine. But since the temparature is too hot (57C) with original HSF, I decide to replace it with Termaltake Vulcano 6+, which is originally install with XP 1700+ on Abit KG7 Lite mobo, running at idle (42C).

So, I take out the XP1700+ from Abit mobo and replace with XP1800+. No post screen, only 1 long beep sound. So, I replace the AGP card with PCI card, no beep sound and no post screen at all. Proccesor spoilt ?

Install the XP1700+ on GA-7DX, working fine. But when I install back to KG7 Lite, same thing as 1800+, no post screen. Now, 2 proccesor spoilt ? I don't believe it.

How to troubleshoot ? How to determine to problem ?
Any suggestion is much much appreciated.
Thanks in advance.
