Question

Nvidia GeForce 9800 GX2 and Story of Distortion and Blue Scr

by Devilz_soul1970 / January 9, 2015 4:52 AM PST

Ladies and Gentlemen. I need your desperate help.

First the setup I have (it's some 6-7 year old rig though)
Windows 7
Motherboard: Biostar TP43D2-A7
Display: Nvidia GeForce 9800 Gx2, Driver Version 9.18.13.3523 - (Hooked up to Samsung 65 Incher through Dennon 2809-CI AV Receiver via HDMI output on the Graphics card)
Processor: Intel Quad Core 2.6 GHZ
RAM: 4 Gig
Sound: Razer Barracuda AC-1
Bios : American Megatrend

So the problem is that the display gets distorted as if the display drivers have stopped working. I am attaching the pictures of the symptoms to show how it really looks.

Initially, when I would unhook the AV Receiver HDMI Cable, attach a DVI cabled Monitor and the distortions would go away after a few restarts and I will then hook the HDMI Back up to the Graphic card. However, for last 2 days, the distortions just won't go away no matter what I do. Its gotten to a point where the Win7 won't even start in normal mode, it will give me a blue screen of death while starting up (Picture link attached)

I have done the following

- Unhooked HDMI and started the rig in safe mode using DVI cable/Dell Monitor
- Used Air compressor can on the whole rig for any dust thinking that may be dust is creating connection issue in PCI Slots
- Uninstalled and installed drivers - Microsoft version. When I download the Nvidia 9000 series driver pack, it won't recognize the Gx2 card at all :/. However MS one install the Drivers correctly with all the Nvidia tools

I have not reinstalled the Windows 7 yet because the distortion starts as soon as I switch on the computer (See picture of the Bios). Which means that the issue starts before Win7 even kicks in? Am I Wrong?

I am completely stumped and have no idea what to do next to diagnose and fix this issue. What I am thinking to do next is
- Check the power supply - But how ? I don't have an extra power supply or rig to swap the power supply
- Check the Ram ?
- Wipe off Win7 and reinstall ?
- Burn the whole thing and just cry myself to sleep ?

I am attaching as many pictures as I can for you to see the distortion during bios, bootup, booted up (before the blue screen problem started happening) mode and also the blue screen of death.

Almost always the video card.

Since it's such an old rig did you try replacing ALL heatsink compounds on both GPU and CPU?
It's cheap and worth a last shot.

There is a risk it's the PSU but I don't see that listed (size, age, etc.)

soft eraser and lightly clean the contacts on the GPU.

If that doesn't resolve it ...maybe it's just time for a new GPU and there's plenty of good, reasonably priced cards to choose from.

Let us know.
