I tried it but it didn't work
PS: I run Gigabyte GA-H61m-d2h Motherboard and tried the drivers from gigabte's website and supplied driver disk but it didn't work
But I use vga only....tried hdmi to hdmi cable but didnt work...maybe a defective cpu/mobo which one? I can get replacement but not sure weather for the cpu or mobo???
edit: actually id doesn't logon to windows just hangs because I dont hear any startup soundfrom my speakers and there is no hdd activity
I'm sorry, that was just an idea...
its okay pal....hope intel solves this irritating problem
it is CPU Problem change Your CPU
