First of all, thanks for reading and trying to help me out. I bought a H61MXV Foxconn motherboard, used it normally for 3 days then it started to not recognize my GPU anymore (Geforce 8600GT). I tryied CMOS clearing and everything but no luck, the GPU cooler was spinning, and the GPU was seated correctly. I went to the Onboard video so i could try a bios update. I used the FOXliveupdate thing from the cd that came with my pc and updated flashed succesfully the BIOS. The program asked me to reboot the system, i ok'd it then it didnt post, just a black screen. i waited like 15 min then turned the power off, when i tried to turn on again the fans spinned for 2 seconds and rebooted continuosly just for like 2 seconds. I researched for 2 days and still no luck, it's an AMI Aptio bios chip, it's 4mb. I hope you guys can help me out in this one, i still have warranty but it will take ages (like 2 months). Specs: 2x Kingston KVR1333D3s8N9/2G, intel core i3-2100, geforce 8600GT, Foxconn h61mxv, hd samsung sata 2 80gb, samsung cd/dvd, PSU C3tech 450W (real) PS: i tried different graphic cards and different PSU's, still no beeps.
