Display Woes

09/13/2011 6:52 AM

I have a computer that's causing me some pain, and I would greatly help your appreciate your help in fixing it. It currently boasts the following spec

AMD Athlon 500+
Gigabyte 780 G chipset motherboard with onboard graphics
2GB 800 Mhz DDR 2 RAM ruuning in single channel mode
250 GB SATA II hard disk ( Seagate ? )
A Jenetech 350 W power supply ( formerly a Gigabyte of 400
Add-on Cards

CreativeSoundBlaster Audigy Value
D-Link DWA 510G Wireless Card
The RAM and PSU were recently replaced as a part of my efforts to tackle the lack of any video display on bootup. Both replacements initially led to the system giving me some display, but then it all vanished.

In the case of the RAM, I got 6 hours worth of display after which the computer gave up. However with the power supply , I did not even get that. Previously, I have had the great pleasure of fixing all my computer's woes, but its predicament is clearly beyond my understanding.



Previous symptoms worth noting in order of occurrence
When new, it tended to shut down after intensive gaming.This was attributed to the heating of the Northbridge, a known issue with the Gigabyte motherboards.
Two years after purchase, it started showing some resistance to high definition video and full screen streaming video.
Lately, the display started going off or not coming on at all.

The AMD processor you cite that I could find a reference to is a twelve year old design that works in a Slot A socket. The Gigabyte motherboard you cite is a much more recent board that has either an AM2, AM3, or AM2+ socket for the CPU.

Regardless of this compatibility and specific component issue, you should make sure that you have the latest software and BIOS loaded. You should also remember that nothing lasts forever. How long have you had this package operating?

Hi Redfred

Pardon me for my typo, the processor in question is a 5000 + and not a 500+. I have had this configuration for the last three years.

Godspeed

Have you tried inserting a graphics card and disabling the on-board video?

That's the first thing I would've tried. I recently had a problem with a mother board with on-board NIC that quick working. Popped in a NIC card, disabled the on-board and was up and running in a few minutes.

I tried this old card, but the problem persists. Moreover with no display, I can't access the BIOS menu.

I haceve written to the motherboard manufacturer , and they suggested removing the battery. Could one do so without a PLC tool ?

Silly question, have you checked all of the loaded power supply voltages with a voltmeter?

No, but I have swapped my power supply with another one and haven't seen an improvement. Where do I check the loaded power supply voltages, on the plugs ?

Also, I know what a battery looks like but how do you remove it ?

Removing the bios battery is usually a simple matter. They are usually about .75" in diameter and about .125" thick, held in place by a clipped battery holder on the motherboard. Removing it for more than 30 seconds usually results in resetting the bios to factory defaults. No special tools required.

It's worth a try. A power spike or static electricity could have garbled the bios settings.

At the least, it eliminates a possible problem.

Here is a common bios battery.

Well as you mentioned, you have a computer board that has a known overheating problem when heavy data shuffling happens like gaming, multi-dimensional mathematical analysis and other large number crunching applications. You've used this board for three years of gaming. The only method you seem to have to troubleshoot your system is to swap parts and look for a complete restoration. You have no test equipment, rework equipment, rework training or even an understanding on how to change the CMOS battery. I think that you need at least a new motherboard. Tiger-direct has one for just $28 plus shipping and handling.
