hi, trying hard not to panic.using friend's laptop to find help.... my own pc seems to have comatised...... yesterday 'tried' to upgrade to new cpu....install seem to go fine..then switch on pc, it powers up-fans,drives,monitor etc normal BUT no beep....blue screen on monitor no words new cpu is compatible with mobo - checked no burning smell - don't think cooked either can someone help... mobo ecs k7s5a cpu amd xp socket A
sorry forgot to add... since new cpu not working, tried to put back previous cpu which i knew would work....but that does not work either now niether orig. nor new cpu works???
Socket A processors require the 4-pin CPU Power connector in the Motherboard. I occasionally forget about that, is it plugged in? That exact problem is caused by the Processor not being registered, so either there's no power going to it, or the motherboard isn't picking it up...
not all socket a boards need that 4 pin connector as i haven't used it except for some p4 boards & i've done upto an amd 1.3ghz.
hi, thx for the reply & suggestion - double checked manual - says nothing about 4-pins. manual does say that 'processors are automatically configured using firmware and a synchronous host/DRAM clock scheme' can someone translate that in plain english?? why then when i tried to put back my previous one which did work, now also not working????????????
To be honest, I doubt a motherboard that originally hosted an Athlon 1250 would take an XP 2800+, although it's the same socket, the components on the board have a limited processor speed they can deal with. However, I wouldn't have thought this would have damaged the motherboard, but since neither CPU works, it may well have done. What is the make and model of your motherboard?
Which, If you don't know is done by removing the BIOS battery for about an hour, then replacing it. It might work, and is certainly worth a try.
sorry chap, in your position I'd get a refund for the cpu, then go and buy a bundled cpu and motherboard. You could be dealing with a faulty cpu, damaged motherboard because of the faulty cpu, or something as simple as you may have been carrying to much static charge when upgrading. Either way, I've found in these situations that trying to change the cpu or motherboard independantly to figure which is knackered is futile if you don't succeed with the first try. PS. sounds like the motherboard is fried for sure, being that you can't get your original chip to work now.
Safe bet, shame it's so expensive... Seeing as you're going for a new motherboard, if your budget can stretch it might be worth trying to get an Athlon64 for socket 939 instead.
thx for helping sammorris & dpp just an update; got myself a 2nd hand mobo, same make as my existing which is an ecs elite k7s5a put my previous cpu in (1250), and it worked!!!!!!!!! so the new cpu must have fried my mobo - very p*ssed off luckily it did not fry my previous cpu. just don't get it was told it was compatible and to just pop it in.
