Hi all.

My system went off last night and straight away I thought it was my motherboard. Now I have had all day to look into it a bit more, it could well be the cpu.

Basically the motherboard powers on and the fans etc start up but there is no display. Not getting any beeps from the motherboard speaker.

It will work out cheaper to buy a new cpu which I could do tomorrow before spending even more and buying a new motherboard.

I was using a 1055T and running it at 3.8Ghz. Now I know it is a big drop but I was going to get a Sempron 140 as it is the cheapest AM3 chip I can find. If it works I will then try and unlock it and run it at around 3Ghz maybe a little more.
 
Well that is what I thought at first but after speaking to someone from Asus they have put the though in my head it could be the cpu.

I do not want to send the motherboard away to be found wokring OK and having to pay for returns etc.
 
Yup sound like motherboard has become faulty.

I had the same problem with my brother's old asus mobo. Once I placed components in new Gigabyte mobo, everything worked fine.
 
i had somethink similiar and it was my heatsink/cpu,swapped my heatsink for the old one that i had and everythink ran fine, in my experiences things only go wrong when you start messing!
 
best way to tell is put the cpu in another computer.

btw, why are you surprised asus tried to convince you that it was another companies product that was the cause of your problems? makes sense to me :S
 
Well I have put the stock heatsink back on and still doesn't work.

I do not have another AM3 motherboard to check the chip in.

I know what you mean about Asus not really wanting to put the fault down to their motherboard but it is either one or the other.
 
well then yeah i guess u better go buy the cheapest 2nd hand am3 cpu u can just for testing and then sell it again when you are finished testing.
 
I have now raised a RMA with the supplier I got the board off. Just going to send it off and wait for a replacement and use my spare PC.

Imo in majority of cases, CPUs are the last component to be damaged.

Generally the way to destroy CPU is to either place too much voltage through it or to increase the temperature tremendously of the CPU by overclocking it at a very high speed, running stress program such as Intel Burn Test for long period of time and having poor cooler so temperatures are hitting like 90-95C. Or simply just remove the heatsink while cpu is under load.

The other way to destroy CPU is to hammer it hard:D.
 
Thanks for all your advice guys. When I first put everything back together I checked the temp in the bios with me installing a new cooler and it was only 36c so got to be the motherboard.
