System monitor shuts off. Computer still runs fine. Please help!
Posted on 2007-07-31
Here are the machine specs:
Dual 2.4 Ghz XEON cpus
1.5 GB RDRam
256 mb Nvidia Graphics Card
80 GB SATA HD
3 case fans, 2 cpu fans, 1 PS fan, 1 Ram fan, 1 Graphics fan = 8 fans total
Win Xp Pro SP2
You might have figured out where I am going with this thread after I listed all the fans I have. Well I think I have an overheating issue but I can't find it for the life of me.
How it displays itself is after a while I get multicolored lines all over for the screen and then after about 2 or 3 seconds the monitor goes black. The computer does not shut off just the monitor. The light on the monitor turns yellow like it does when it doesn't receive a signal from the video card. However the computer is still running ( I know this because today I had the internet radio playing and it continued to play even after the monitor shut off).
The first thing I did was open the case and use my desk fan to help cool everything. I initially thought the video card was going bad so I purchased another one. The problem continued.
My next thought was either the ram or the cpus. I didn't have any extra ram so I removed one of the cpus and ran it that way. Well after a couple of hours the machine messed up again so I swapped the cpus and ran the rest of the day with no problems ( I still had my desk blowing into the open case).
The computer ran all day and nothing happened (although I did turn the computer off during lunch). Still had the desk fan blowing into the open case.
Didn't run the computer. Did research at home. Read where to tell computer not to reboot on error.
After 2 hours the computer messed up again and gave me a blue screen with this info:
STOP: 0X000000D1 (0X00004497, 0X00000007, 0X00000000, 0XB98B180B)
NV4_mini.sys Address B98B180B base at B96FE000, Date stamp 4269449f
This sounds like a video driver issue but the computer has messed up again and I have never gotten another blue screen, just the multicolored lines all over the screen.
I remembered I had an extra memmory fan so I installed it.
The computer ran for 8 hours today before I got the multicolored lines. I removed the desk fan after I installed the memmory fan.
I am at a loss for what to do next. Can someone please point me in the right direction? Offer some good information?
