Advanced PC Problem

By Michael34 ·
Hello,

This is the situation, The person whom's computer I am attempting to repair had windows 98 SE installed, and kept getting several errors and blue screens, so I upgraded to Windows 2000. Once the setup was done, I decited to install SP3, which I had things to do, so I started the setup process, and when I came back it was blue screened.

When I proceeded to turn on the PC once more, all that happens is the Yello HDD Light and Power light come on solid, then after 30 seconds the HDD LED goes dark. The Monitor gets NO signal and remains in standby mode. I thought it was the monitor at first, but the monitor is a known working one. Anyways I removed the Hard Drive thinking it may be causing problems, but it was not.

I noticed the system was very very hot, so I called the person and found out that this PC, had been running for about a year with NO fan, only a heatsync on the Processor, which would explain the error messages in windows 98.

To confirm this (Before it went dead) I was unable to install anything, the setup would lock up, so I put a fan by it, and it would do setup and thats how I got windows 2000 setup on it).

Now what could have gone out, to make it where I get nothing when the power is turned on? The monitor is getting a signal, but remains in standby, but if I take the Monitor cord off it says "No Signal Detected", and the monitor works fine with other systems.

I also replaced the Video Card, and still nothing. Any clues????

So you agree it is the System Board? The PC is a HP Pavilian 9695C, and it only a few years old. I checked the Power Supply and it works fine, as does the fan with it. I was able to rule that out at the start. I am ruling out the Processor and Ram, JUST because it will not enter BIOS, and I figured that if those components were damaged it would not display the correct information about them.
Thanks For the help.

Alright,

I was informed by another tech I have worked with for several years to remove the CMOS Battery and wait for a hour, which I did and after an hour it finally showed me the bois information which I have listed below:

Phoenix Bios 4.0 Release 6.0.e

CPU: AMD Athlon(tm) Processor 850
640K System Ram Passed
255 M Extended Ram Passed
System BIOS Shadowed
Video BIOS Shadowed
UMB Upper limit segment address: E94F
Mouse initialized
Fixed Disk 0: Maxtor 94098U8
ATAPI CD-ROM: LG CD-RW ced-8083b
ATAPI CD-ROM: Pioneer DVD-ROM ATAPI Model1 DVD-114 0124

When I push F1 to enter setup it just freezes and says Entering setup, but never enters setup. Also I have the CMOS Batterydisconnected, as it is the only way I can even get to this information. If I plug it in, it will give me the info, however when it restarts it just does nothing.

I am saying the system board itself, would this be correct?

If this is a socket A system, I have seen a number of systems that have problems when you allow the BIOS to automatically set the CPU speed.
I now ALWAYS set socket A FSB and CPU speeds manually.

If a socket A, I would start with a new CPU first. They run VERY hot, and really need a fan all the time.

Even if it is a slot A system, I would try a new CPU before the main board.

If it does turn out to be the main-board, I would suggest that the customer invest in a new system instead.

First, you may have problems installing anything other than a HP motherboard. Once you check the cost, you will see why I suggested a new system.

Second, should the owner ever wish to use the restore CD, it will usually error out if the motherboard is not a genuine HP.

TheChas has it on the nose. That processor is literally "hot". Should never have been installed
without a heatsink fan.
My advice would be to do as Chas says.
I will add that the cpu may be okay if you are still getting any post at all. I doubt if I would ever trust the cpu or MB again. Good to dink with or set up for "kids".
It is a shame on some one for that to leave any shop without the cpu heatsink fan installed.
cannon fodder me thinks.
However in my shop I would check the cpu in a good MB with a GOOD heatsink fan [yes AMD heatsinks are huge] and use it myself. Same with the MB. If all checked out it would only go "kid"
for games.

Whoever said that the AMD 850 doesn't generate much heat is incorrect. I have a AMD 750 that requires 3 fans to cool it in a 80 degree room and it had problems with 2 fans in 70 degrees. The CPU eventually took the Mainboard out. Good luck.

I have a slot amd 800 for almost 5 years now on an asus k7m mboard. it has dual fan heatsink and now i made it as my redhat 9 fileserver with promise ide-raid 1!! This is where i am writing this response right now. i could say that this amd system is one of my most stable systems so far it just runs forever. i have a new p4 2.4 on gigabyte and it already rebooted without warning just within 3 months! Another one piii 1.2 celeron is almost stable but i had problems in APIC implementation.

Your system just got too much punishment resolving it wouldn't justify cost and time. MB or CPU or RAM what would you do? Your BIOS/CMOS info is just about 25% of the whole thing. Believe me your system will never be stable no matter what you do with it.
