Aopen mother board diagnostic light lite up

I have a AMD 1700* Build with a aopen Proak73(3) thunderbird motherboard - recently when i turned computer on it would shut down after several attempts i could get computer to boot up - at first i thought it was a power supply going bad because fan on supply wasn't turning - i got that problem repair yes by spraying just a little dw40 lube on base area of fan - sometimes the computer will boot up saying your computer may have a CPU problem and upon several attempts i have been able to get computer to boot up - the motherboard has a red LED lit up on it for a few minutes after it shutes down when the computer doen't boot - i've told by a friend that this is probably a bad motherboad ? Suggestions and if you agree How much Damage in Dollars am I looking at for Parts - my friend suggested getting a board with a CPU also since the other could be fried?

Re: aopen mother board diagnostic light lite up

Three in One Oil & DW40 are not suitable for lubing a fan. What you need is a good lubricant. Axle Lub is a good lubricant, it is resistant to break down by heat (it does not evaporate) and a good solid lube. Good to your local General Department Store, which has a Auto Repair Part Section, and look for a good lubricant there. You'll need to open the reservoir that the lube is put in, wipe it out, and put the lube you purchased in.

I have two Antec, both over three years old, fans are just doing fine. The big case fans slowed down, after the first summer, the lube started to evaporate from the heat. I'm sure that's a common problem.

Sounds like a RAM compatibility problem. Check to see what ram is supported in that board, and if thats what you have. Kahlon has good prices on RAM

My pc processor not hit when on the mother board my mother board is aopen mother board plaese give me salution

If you mean that your processor pins does not fit in your motherboard, then they are not compatible. The processor pins must be exactly fit the motherboard.
Besides, the processor type must be supported by the motherboard (If the motherboard is supporting P4, Core Dou, Quad, Celeron, Athlon, etc). You have to install the right processor for a particular motherboard. You have to know what particular
processor is supported by your motherboard.. In your
case, I believe it supports Pentium 4, but I cannot
give you the exact speed in Ghz, as well as the clock speed. You can ask the dealer about it.
