Few weeks ago my 8600gts 256 mb graphics card started showing broken screen, i reflashes it BIOS several times but nothing happened ,then few days it started working absolutely fine, i was again able to play games @ high settings, but then after 10 days it has totally stopped working !! when i turned on my PC, my monitor gives me an error that says : No signal input. The graphics card fan is working fine, but its not showing any display at all !! what does that mean ? is this because of over heating ? because there is no extra fan for graphics card & my graphics card seems to become very hot. Here are my PC specs : Inte Core 2 Duo 2.0 Ghz Intel DG 33FB motherboard Two Kingston 1Gb ddr2 800 mhz ram MSI geforce 8600 GTS 256mb PSU : Standard 400 W power supply
