Hello,
I have recently built a new pc, it has been working fine for around 3 months until the other day. i turned it on all fans are spinning and green mobo light is on the monitor picks up a signal but there is no picture. I have gone through the checklist given by this site twice but still no luck.
Basic specs.
Asus p8h67 m-pro
ATI HD 6770
Intel i5 2500k
2x 4g Kingston hyperx ddr3 ramb
CIT 750 watt psu
I have never overclocked, and have replaced psu + tried a different monitor.
Any help would be greatly appreciated.
Thanks
Ben
