After 18 months my Q6600 may have gone bang. The system starts and fans turn but no output to the monitor, mouse or keyboard.

The hard drives turn but it is clearly not loading anything.

I have swapped RAM about and reset CMOS

So, CPU, motherboard or something else????
 
Strip down and try to start with bare essentials, try different psu, one stick memory etc.. if no go then i'd likely suspect the board before the cpu.
 
I would be surprised if your cpu gone bang, I echo what Justintime mentioned above.
If there any possibility to test your parts in another system.
 
It sounds like a PSU failure someone I know had, and probably more likely.

Like the others said, strip out as much as you can and work from there.
 
I've abused CPUs for years and had nothing like this.. most major faults have been the mobo tbh.. damn things break quite easily.
 
ok thanks.....The board is asus p5b. The power supply is a corsair 620. I have tried different RAM bit no change. I got an overclock fail message yesterday and that resolved after I switched it off at the plug.

Prob now is which bit to replace......bum
 
Never heard of Q6600 giving up the ghost, they've been well abused by peep's in this forum, like the above say check power supply, etc 1st.
 
ok. Stripped the whole thing down. With only MB and CPU I get memory beeps nice and clear telling me they are not in. Put the existing memory in (either stick in any socket) and the beeps stop. No beeps to suggest no GPU or any other hardware failure. The Keyboard is still locked and the mouse does not light up. GPU is still out and there is no change if I put it in.
So, what next. Multimeter to check the power supply. New RAM (seems odd that both sticks have gone wrong) or deduce a knackered motherboard and shell out there. ????
 
Suspect motherboard.

Tbh though it could be the PSU and it could be the memory. If your PSU has given up the ghost it might have taken the memory, cpu and mobo with it. Hopefully that's not the case.
 
I have just tested the voltage at the PSU and they all bear out right. I guess it is not that then. Just built a second pc on old hardware but the MB has a PCIE socket so ill be trying the GPU tonight.

I am thinking motherboard. Damn thing is only 14 months old
 
You could try a full cmos reset, but that normally only helps in cases where the fans dont even spin up. Anyway can still try it... Remove all power cables to from the PSU to motherboard, remove battery, apply clr cmos jumper, and leave it for 30 mins (or overnight if you prefer).

Then return jumper to normal postion, reconnect power cables and replace battery, and see if it works.

I wouldnt be too hopefull though, as normally this fixes motherboards that wont start POST, and your's is clearly starting up as you get the no ram beeps.. but wth.. its a cheap test :P

AFAIK, most boards trigger a beep with the GPU disconnected, so clearly something is amiss.
 
Overclocked to 3.4 and on auto. I tried my 8800 gpu in an old asrock pci e board and it just sat there. I also have an old PCIE GPU out of a dell that seems to work on the asrock (hence this post) but does nothing on the newer asus. I am thinking gpu at the moment.

I shall fix it.
 
Fixed it.
A mate lent me two sticks of generic ram and it booted. Allowed me to set bios up and now all my components work. Including the original RAM. It seems my overclock that has run happily for 12 months finally broke and no resetting bios would help.
Ballistix ram had a rep for being sensitive and i think it is....

I am back ontop and my beloved machine is alive.........
