Hello, bit of a scare, and an annoyance. After finally having F1 2010 unlock yesterday afternoon, I was excited to get started. After a few hours playing, there was a massive problem. There was a pop noise, and the computer shut itself off instantly, no BSOD or anything of equivalent sort of style. I believed I could smell a funny smell, but I may have imagined it. The computer rebooted, and the graphics card fan came on at full. I was too scared to start it again last night, so I left it. However, when I went to start up this morning, the computer would start, but not POST. I looked inside, to see what I could find, and nothing seems to have blown on the motherboard. I can only assume it was a capacitor on the Graphics Card, but, I can't check with another graphics card, due to not actually owning another one, and I don't want to remove the shroud. So, I have the problem that it's either a mysterious Motherboard related error (or things appended, CPU, RAM etc.) Or my Graphics. My Specs are: Core 2 Duo E7200 clocked to 3.6GHz at 1.3v (Air cooled with generic, yet decent, thermaltake cooler) Coolermaster HAF 922 Case (So, over-heating's unlikely) Asus P5QC Motheboard 4GB DDR2 Ram XFX Radeon 5850 (Which might be the culprit, shame as it's only 6 months old) 640gb Hitachi HDD (which is fine and checked) OCZ ModXstreme Pro 600w PSU (which I also believe is fine, due to it starting the system up. Also, A generic PCi wifi card, and Asus Xonar DX Thank you for your time, and if you need any more info, I 'd be happy to help. Incidentally, that's how I feel right now; HELLLPPP!
