Thought I would upgrade my old socket A system on an Asus A7m266 from an Athlon 1400 to an AthlonXP1800+ as the slightly faster chip was handy. Should have left it alone as it as all gone horribly wrong!
Blank screen on inserting the 1800 cpu, everything powers up but no POST. Replaced the old 1400 CPU and still no POST. Cursed a lot and bought a new mobo, Abit KV7, still no POST with either cpu. Swapped to another stick of RAM, still no POST.
Have tried both CPUs in another machine with 3 different sticks of RAM, still no POST.

Question:
Have I killed both CPUs?
or
Have I killed all 3 sticks of RAM?
or
Have I killed all 3 motherboards?
or
Other...

Suggestions please?
Many thanks!

How about your power supply? You may have exceeded it's limits. Is this in an HP, they have pretty small supplies.

Same problem with three different power supplies. 2 of them Enermaxes.

I seem to remember a jumper on that board for cpu types. Also, put your old system back but reset your BIOS, you can just take the battery out for a minute or so.

i agree with tyger...when putting a new cpu into an existing board y ou have to reset the bios...you may need to move the jumper on the board to fully reset it....taking the battery out doesn't always work..just follow the instructions in the manual..or post back here with the model number so we can find you instructions.

I have tried resetting the bios - in all 3 motherboards + taking the bios batteries out, pressing insert on power on, and a dozen other tricks. I have tried everything and know that at least 2 components are dead, my quest is to find out which ones!

Hi,

Have you considerd it could be a bad video card and have you tried another?

If you have tell us on witch board

I had tried 3 different video cards...

Managed to get hold of another cpu this morning and that did the trick. I believe the answer to the question was therefore 2 dad cpus. Just one more chip to buy and I hope to have 2 complete systems once more.

Thanks for suggestions
