Hello,

Due to some compatibility issues between the memory ram and my former mobo (MSI P45 Neo2), i decided to buy new memory rams (Corsair XMS2 ). The problem was that, after i booted into Windows and tried to play some games, the BSOD appeared. I tried memtest and i found out that there are some problems with my memory. So, I bought the Corsair, but the problem remained. I thought that the mobo was the problem (MSI P45 Neo2) and I bought a new one (Asus P5Q Deluxe). I installed it and I started the PC. After a few seconds I smelled something weird, like some burned plastic. I've restarted the PC, thinking that smell was from the thermal paste, but it continued to smell, until the PC shutted down. I tried to start it again, but when I do that, the cpu's fan starts to spin (for a millisecond) and stops, the video card's led turns on and off very fast. If I remove the 8-pin cable, the cpu's fan spins normally, so does the videocard's led and fan, but I don't get any image on my monitor.

I changed back all my components to my former motherboard (MSI P45 Neo2) and the PC started normally. I said that I'm going to use this mobo until I find out what's the problem with the new one (Asus P5Q Deluxe). But, after connecting all the components, my PC was behaving in the same way. I removed all the unnecessary components, leaving only the cpu, video card and mobo, but it does the same.

The CPU is a Intel core 2 Quad Q9550 @ 2.8 GHz
The PSU is a X-Power @ 700W
The video card is a Sapphire Ati radeon hd 4890

If you need other details, please let me know.

Thank you very much.

Hi newcomer and welcome to the Tom's hardware forum.

Test the rig with another PSU and GPU and test the GPU in another rig.

I tested it with another PSU...same result. I'm pretty sure that the GPU is ok. The question remains: which one is broken, the motherboard or the CPU?

I think that is the motherboard since a faulty CPU isn't commune.
