Hi. Yes, i seem to have some sort of substance on the back of my motherboard. Lemme give ya the quick rundown on everything The mobo is an Abit IS7-E, which ive been using for about a year or so now with no troubles. I read some other post's on the site about fried motherboards and i have all the typical signs and symptoms. Fans only do a small shudder then everythings dead. I switched out the psu with another to check that, same thing. I checked the cpu in another mobo, and it works fine. Both my 512mb sticks work fine in the other mobo. I checked all the jumpers and all connections, everythings where it should be. I didnt notice any blown resistors or anything like that, but when i took the board out i saw that it had streaks of a white substance on the back. Almost like salt stains or something. Anyway, i just wanted to see if anybody has ever encountered this before or what might cause it so as to avoid a similair mistake on the future. If ive left anything out lemme know and ill post whacha need. (Besides this was a great excuse to go get my IC7-G Max III....lol) Thanks for your time.
