No video problem
Hello All,
I'm troubleshooting a PC that doesn't provide any video. When I move the memory around in the slots and reset the CMOS I get a long beep, one after another. If I restart the computer the beeps stop, but the computer fails to show any video. I can't tell if the system goes through POST or not, it seems it doesn't but if I turn the system off I have to hold the power switch for a few seconds indicating to me that the POST has completed and the OS is loading. The monitor seems to get some kind of signal from the video card since it doesn't power down at all. I have done the following in order to correct the problem: - Removed PCI and ISA cards form their slots - Removed the memory and swapped them around to check for a bad stick - Removed all but one stick of memory - Check video using original AGP card - Check video using known-good PCI video card in different PCI slots - Reseated CPU - Pulled motherboard out of case and tried to boot with CPU, memory and video card only - In all cases I reset CMOS before trying to boot Nothing has worked leading me to believe that it is possibly the CPU or motherboard which is at fault. One thing that makes me think it is the CPU is that I remember that the person who owns the PC said that he was having a overheating problem. When I check the CPU the heatsink was on VERY loosely. The CPU barely made an impression in the thermal pad, and had no grease on it at all. I'm thinking that it has been running hot all along and finally failed. Unfortunately I don't have a CPU to replace it right now. It's a Celeron 466 in a slocket. System specs: Abit VA6 motherboard Celeron 466 in slocket 256mb sdram (all different makes) 2x64MB and 1x128MB Hope someone can tell me what I'm missing. I would appreciate it. -- Pat - pat(underscore)blank(at)hotmail(dot)com |

Sounds like you covered all the bases. Given what you indicate regarding the
heatsink/fan being loose, I would have to agree; the cpu is most likely shot. "Pat Blank" wrote in message . .. Hello All, I'm troubleshooting a PC that doesn't provide any video.
