After 18 months of being absolutely fine, I've been having increasing trouble with my PC.
If I try to wake up the PC from sleep within 2 minutes of putting it to sleep, it will fail to wake properly 100% of the time (lights, fans etc come back on, but no signal to monitor or AFAIK any processes running etc)
If I try to boot the PC after shutting it down, it will fail to POST around half the time. No POST beep is made, nor any error beeps. At no point does the monitor receive signal, but all the fans seem to start.
When it doesn't POST like this, my gfx card (Radeon 4870) gives three solid red lights (D1601-3, http://forums.amd.com/game/messageview.cfm?catid=260&threadid=97885), so I figured it was the gfx card and bought a 5770.
However, the PC still fails to POST! I've tried unplugging 2 unnecessary SATA drives (blu ray and USB extension) but still doesn't POST so figured it wasn't the PSU - but now I've ruled the gfx card out (ruling out the new 5770 being DOA as that would be terrible luck!), could it be the PSU? Various threads on the 4870 three red light issue suggest PSU if no the gfx card - as it's not the card it's likely the PSU right?
Any help would be most appreciated, I'm going crazy and can't afford to keep getting new components!
Thanks in advance for any help, spec below in case that helps!
