Hello everyone. My motherboard appears to have been fried. My setup:
Case: 450W PSU with additional case fan
MB: Abit AB9 Pro
CPU: Intel E6850 (Core 2 Duo @ 3GHz)
RAM: 2 x DDR2 1GB 800 MHz
GFX: Gainward GeForce 8600GT 512MB
HD: WD Caviar 250GB SATA II 7200
Optical: Samsung 20x SATA DVD-RW
Monitors: Dual Monitor setup - Asus 22" + AOC 17"
USB: Scanner, VOIP phone
PS2 mouse + keyboard
The story - I got all components 15 months ago. I had some initial problems with the FW that came on the AB9 Pro, but once I updated it it all seemed to be good. About 2 weeks ago I got the Asus monitor and set it up as the primary display via DVI, and kept the AOC on RGB as a secondary display. So far so good.
I decided the best way to test my new monitor was to play a game, namely GTA IV. Since my new monitor is a widescreen, I had to modify the resolution. I found that I needed a higher resolution for display on the new monitor, and the game suffered some performance issues.
Yesterday, I decided to check for new drivers for my GFX as I know there have been some serious issues getting GTA IV to run smoothly, and drivers keep getting updated. I downloaded and installed the latest nVidia drivers for my card (v. 181.20) and started the game. I'd been playing for about 90 seconds (much better performance with the new drivers) when the screen went black, and the computer restarted. It tried restarting about 9 times in a row, but would die (with a horrible moaning sound) every time. I unplugged the computer. The first thing I thought was there might have been a power surge, but I'm using a surge protection extension for all my computer stuff, and there was no other indication that there had been one. In case it was simple overheating (unlikely after 90 seconds of play, but still...) I left it for a couple of hours. When I came back I unplugged all peripherals and left only the primary display, mouse and keyboard plugged in, and started up the computer. It got as far as the BIOS splash screen, then artifacts appeared and it hung. I tried plugging in the secondary display on its own, and in combination with the primary, but I still didn't manage to get past either a black screen, or a corrupted splash screen. I've gotten all sorts of POST codes:
C5 - this is the code I get most often, the description says "Call chipset hook to copy BIOS back to E000 & F000 shadow RAM"
Whenever it actually manages to get past C5, I can get any of the following:
03 - "Initial Superio_Early_Init switch"
10 - "Auto detect flash type to load appropriate flash R/W codes into the runtime area in F000 for ESCD & DMI support"
25 - "Early PCI Initialization:
- Enumerate PCI bus number
- Assign memory & I/O resource
- Search for a valid VGA device & VGA BIOS, and put it into C000:0"
52 - Test all memory (clear all extended memory to 0"
FF - "Boot attempt (INT 19h)"
Now for my questions:
1. Is this likely to have been caused in any way by the new drivers for the GFX or is that a complete coincidence?
2. What is likely to be the issue here? The motherboard, the GFX, the memory? Or could it be more than one component?
Thank you in advance for any responses, as I've never had anything like this happen to me before.
Regards,
Patrick
