This is a very very strange situation. Every time I turn on the stove, the PC shuts down. I am putting this in power supplies, because it is power related, but at this point, I suspect that it's the 6800 GT that is causing the problems. Last night, I put a supposedly dead PS in, put in a 6600 (which I know draws a lot less power) so that I could finish watching the movie that was so painfully interrupted when I fired up the stove to make dinner. This is the third time that turning on the stove has caused my PS/Video card combination. The reason that I suspect the video card is that this is the third system that it has been in (with completely different parts) that had problems coming up. Okay, I have threads here and here . Yes, I do need a new power supply I guess because it's a crappy brand, but is it possible that the root cause of this whole mess is the video card? I realize that it draws more power, but I'm at a loss as to why turning on the stove (which is in a different part of the house) affects the PC. Right now, I have an el cheapo PS and the 6600 in the PC. It worked with the stove on, which is nice. It sucks, though, for games. My ultimate goal is to get an 8800 GTS, but I've been waiting for price drops, and frankly, I'd like to get the box stable before putting in a much more expensive card. I'm now starting to believe, though, that no matter what PS I put in, it is going to crap out with the 6800 GT. I'd deeply appreciate input from some of the PS gurus to help me pin down this issue. Do you think that with a better PS (It's a highend Rosewill - yes, I now know it's a crap brand, but it's the top of the line of their crap line and it's fine if the stove is off) I can get this thing stable? If so, I'm thinking I need something of higher wattage (or am I off the mark) than what was recommended in the other thread (XCilio GoodPower 500 was recommended). I have in this box a non-OC'd San Diego 4000+, 2 GB RAM, 2 SATA drives, M-Audio 5.1 sound, DVD-RW, and eventually a Geforce 8800 GTS. Has anyone seen a video card cause problems like I describe because of it having issues? Or do you think that ultimately it's a PS problem, and I will get a new one and the problems will all solved if I put the Geforce 6800 GT back in with a new PS? I'm getting a new PS today. I will be ordering from Newegg. It would be nice to be able to use the 6800 GT until I can get the 8800 (waiting for price drops). I will be returning what I have. I am willing to spend ~$85. Is the XCilio still the best option, or should I get something else? I'd like to get something powerful enough so that I don't have a revisit of this problem. Thanks for any ideas. It is greatly appreciated, and I will be getting a new PS today.
