Computer not connecting to monitor or USBs

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.

PSU is a StealthXtreme 600W.

It's brand new (few weeks old), my old PSU gave out after a power surge. The rig was working fine until now, after one (normal) car journey.

the psu looks like a re-badged fsp supply

i would be running a corsair 650/750 in the system

Considering it took a car journey, I would reseat the RAM & GPU and check all the connections very thoroughly.
I would be more suspicious of the Geil RAM than the PSU. I have seen many issues with that RAM brand.

Reseated the RAM and GPU, still nothing.

The PSU brand is OCZ, was under the impression they were one of the more reliable brands. Likewise the RAM has been perfect for the 18+ months I've had the computer, and even after the PSU change a few weeks ago.

On an interesting note....found that the motherboard doesn't have an onboard speaker, and nor does my chassis. Was wondering why I couldn't hear any warning beeps.

I've tried resetting the CMOS more thoroughly (taking out the battery etc), still nothing.
