My issue is: Computer fails to POST, power light on mobo is on, fans spin up to max as is normal during POST for this mobo but there's no POST beep (have pc speaker) no output to monitor, and the fans remain at max, which is not normal.
The only symptoms before refusing to POST were occasional/sporadic freezes which required a restart during more graphics/processor intensive gaming - also it did manage to boot a few times before completely refusing to POST only to get stuck on the initial Asus P5NT-Deluxe screen (so it was a fairly gradual decline rather than a completely sudden failure).
No signs of burn outs or damage anywhere.
Have disconnected cleaned and reseated all cables, cards, and CPU (including repasting thermal compound). Removed all dust.
Tried booting with no ram / gfx card, every combination of ram modules in different sockets etc (no beeps still). Reset CMOS jumper / changed cmos battery.
obviously wont boot off CD since it doesnt POST... after trying all of the above, symptoms are exactly the same - so it led me to think mobo or possibly psu, but i thought mobo.
Could be either the motherboard or power supply. You'll just have to do basic troubleshooting and decide which one you want to replace first. The ps can be tested with a simple ohm meter, but sometimes it's not conclusive. Good luck.
I like the second option of going for the socket 1155 motherboard and the i3 quad core - looking at the dollar price i thought that was affordable but finding a direct correlation to UK prices was harder, would this motherboard be equivalent to the one quoted from tigerdirect? :
