I have a Samsung 193V 19" LCD and a BFG 6800GT. Recently, when I turned the PC on something in the case made a crackling sound and I smelled smoke. I tried it again and it did the same thing. The third time everything came on but the video display was all garbled. So I took the BFG out and put in a cheap video card to test and sure enough it worked. I sent off the 6800GT to BFG and they replaced it with a new one. I put it in and everything came up fine- or so I thought. About 15 minutes in, my Samsung monitor made a sound like when a new periphereal is detected and blanked off for a second and then back on. I went to check the display properties and noticed that instead of it showing as Samsung, it just said analog monitor. So I reinstalled the monitor drivers and it came back up as a Samsung. However, it lasted about 15 more minutes and reverted back to default monitor. And while it is registering as a default monitor it will go off for a split-second and then come back on. It does this several times in a five minute period and makes playing games impossible. Can someone please provide some insight or make a suggestion to fix this problem? I'm starting to wonder if the monitor was fried also and needs to be RMA'd.
 
My 1st thought is this. Is your power supply up to the task of the BFG card? Do you have a different PS you could try. I would start there.
 
I would test the monitor on a different computer. That is, if you have one handy.
 
Thanks for the suggestions. I've been running the GeForce fine for the past six-months on a Thermaltake 420w power supply so I don't believe that is the issue. I have another spare computer and monitor so I will swap them out. Thanks again for the input.
 
I was testing out my PC again today and the monitor started going out again every few seconds. It would stay off a couple seconds and then come back on. I noticed that the monitor power light was on the whole time though. Also, the last time it did it the screen got kind of wavy. I'm still not sure if it is the video card or monitor. I have hooked up a 15" CRT for test purposes but have been unable to duplicate the problem. Any more ideas on whether it's the montor or video card based on these observations? Thanks.
 
Problem solved. It was indeed the monitor. I hooked it up to my file server and it started doing it within twenty minutes. I called Samsung and they are shipping me a new one. Thanks to the two of you that offered help and suggestions.
