Dead PC - advice please !
HI All
Apologies in advance for any funnies with the format of this posting, my copy of 'agent' is on my main PC, which is 'a bit broken' g Main PC is an I-friend (from CPC). It's been on&off reliable over the past 2 years - spec is Celeron 1.7ghz, micro-atx, motherboard spec VIA P4M266A + 8235. On Saturday night the PC was left on standby - on Sunday AM the PC was sat with both front panel lights 'on' (HDD & ?power?) but completely unresponsive to power switches, keyboards, mice etc... Removing power & reapplying didn't result in any further activity, no disks spinning up, no beeps, no POST. It appears that i-friend have disappeared - sent them a couple of emails but no response so far.... Had a look inside (my PC-assembling expertise ended at the '486 stage!) - found that one of the PSU fans was jammed stationary - so located a new PSU, ordered & fitted it, and same 'dead' symptoms still apply..... So - suggestions as to a 'next step', please ?.... Can't seem to find a replacement Celeron 1.7ghz anywhere - can anybody recommend a good, cheapish, motherboard / cpu bundle. Application is just email, web, bit of paintshop pro, web authoring - nothing all that fancy..... g Alternatively - and looking at the cost-effectiveness of the whole thing - any suggestions for a complete replacement system unit.....? Many thanks in advance Adrian Suffolk UK |

Have you taken a DMM and checked the operating voltages coming from the
power supply to the motherboard and drives? "Adrian" wrote in message ... HI GB g. beat @ wrote: "Adrian" wrote in message ...

Hi Art
Thanks for the reply Art wrote: Have you taken a DMM and checked the operating voltages coming from the power supply to the motherboard and drives? Yes - +12v and +5v present and correct. They were actually there with the original PSU - but I guessed (wrongly) that the seized fan in the original PSU might be causing a problem.. Regards Adrian |

Have you tried basic troubleshooting like removing all the drives and cards
and reseating the memory then powering it up? If that doesn't work, remove everything except the processor and power it up. It should give you some beep codes (memory or video) if the board and processor are working. - Mike |
