No Video On Boot

[dnshaw]

I just recently brought my computer (1.4 ghz athlon, Asus KT133A chipset, other standard components) back home from school for the Christmas break. When I put it back together again, and turned it on, the power came on, the drives spun up, and I think the monitor might have gone bright for about a second, but no display came up, and no other harddrive activity occured. I started switching out and removing components, such as RAM, video card, and finally the CPU. The CPU I used was from my brother's computer (1.2 ghz athlon, Asus ALI Magic chipset). Even after doing that, the problem persisted, and now brother's computer does the same thing. The only other component I took out of his computer was a stick of RAM, which I have also removed from the occasion. Both CPU's have a small nick on the top left corner of the core, but other than that are fine. Even after purchasing a new CPU for my brother's computer, it still behaves the same way. Is it possible that when I placed his CPU in my computer and possibly fried it, and then put it back in his computer, that the bad CPU fried his motherboard as well? I'd really appreciate some help here. Thanks a lot. My e-mail address is dnshaw@phc.edu.

Hey,

I'd like to know what the your phrase, "put it back together again" means.

Did you have the computer working at one time, but then moved it, and re-hooked everything up and then no video?

The video problem is probably because of a loose connection somewhere. Check all connections and make sure the vid card is fully seated.

However, you now have another problem. When you switched out CPUs, did you use any kind of thermal protection when you reinstalled them? Such as thermal phase change tape, thermal paste, etc?????

If not, and you just installed the heatsink back on the CPU without any heat conductive material between it and the CPU, then most likely you fried the CPU, probably both of them. An Athlon processor will fry in about 10 seconds without proper cooling.

The little chips on the die are worrisome, and it may have something to do with the problem.

A bad CPU will not allow a system to boot. Not sure if a bad CPU would wreck a motherboard. Not likely, I think.

Hang tight for some more opinions, before you run out and buy yet another CPU or two.

Good luck and post back with questions or progress.

Welcome to pcguide

The initial problem could have been caused by numerous things caused by moving the PC back home for your break time. Something came loose and/or unplugged probably.

From there things went downhill in a hurry.

Both of the CPU core-die's are damaged (chipped) from installing the HS/F. They can now be used for key chains.

Brother's Mboard has been damaged by a bad CPU. Please don't try that CPU in any more boards. The ZIF socket takes a Hit. -- Been there and done that.---

So for the new CPU you purchased there isn't any reason why it shouldn't still be operational. As your brother's Mboard was allready non-functional.

Man, when it rains it pours.


Luck.
