ok 2 months later...
i ordered the motherboard and it came i switched it out and bench test and the cpu fan will only turn on for 2 secs, then stop....i knew it wasnt normal behavior so i check the memory, i reseated the cpu and made sure everything is clean. but the fan wouldnt turn on.
I put everything together, hoping for the best, and it actually worked, most importantly the display worked, which was why i needed a new mobo in the first place. but then all of a sudden BLUE SCREEN and the whole system shut off. It overheated because the cpu fan NEVER TURNS ON. i switched the fan back over to my old mobo, and viola it works fine. but when i put it on the new mobo, it just starts and stops. I looked through different forums and found that maybe they shipped me a faulty motherboard, so i sent it back and asked for a replacement.
The new one came today, and sadly, the same thing occurred. This time i ever did a barebone test. Only the mobo, the cpu fan, and the power. But it didnt work. I tried the same test on the old mobo, and it works fine ( the fan stays on) .
I have tried almost everything, am im running out of idea. This is already the 2nd new mobo. I don't think its the fan, because the fan works fine with the old mobo. So i don't know what to do. I tried changing out the CMOS battery, I even tried not letting the cpu fan touch the mobo because some ppl have said that it caused a short with the power.
Please help, i have been laptop-less for 2 months...
