Hi

So my pc is three years old, always been stable. Tonight it just froze whilst browsing internet, had to hold down the power button to turn it off.

Alas, it won't now boot or display anything. When I power on, all fans spin up on cpu cooler, case and graphics card but they seem quieter than normal. After about 10 seconds it will power off, then about 5 seconds later it will power on again and seems to stay powered on.

No beeps from motherboard speaker and no display on screen. I do get the red "Ram OK" LED lit on the motherboard as well.

I've checked all the power connections on PSU, M/B and GPU, all are in place securely.

I've tried another graphics card but that didn't make any difference.

I'll try and get another PSU to test with.

PSU is XFX 650W XXX Edition Modular '80 Plus Bronze' Power Supply bought from ocuk in Feb 2012.. Anyone know if this would still be under warranty ?


Rest of spec:
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail
Asus P8Z68-V GEN3 Intel Z68 (Socket 1155) DDR3 Motherboard
Crucial RealSSD M4 64GB 2.5 SATA 6Gb/s Solid State Hard Drive (CT064M4SSD2)
Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMX8GX3M2A1600C9)
Gelid Tranquillo CPU Cooler (Socket 754/939/940/AM2/AM2+/AM3/LGA775/LGA1155/LGA1156/LGA1366)
+ a couple of old disks

Thanks
