My problem is similar to the one above, not sure on forum policy regarding where to post similar problems though.
My computer isn't putting out a monitor output or connecting to USBs. When powered on, all the case fans and the CPU fan come on, as well as the little power LED on the motherboard signalling that it has normal power. The RAM appears to work (the LEDs on my RAM stay lit).
It's a desktop and did undergo a car journey a few days ago, didn't try booting it til last night to find it wasn't working.
Motherboard- Asus P5Q Pro
CPU- Intel Core 2 Quad Q6600
GPU- Radeon HD4850
RAM- 2 x 2Gb GeIL (DDR2)
All help appreciated, tried resetting the CMOS and it didn't work.
