BK1 Posted November 6, 2010 Share Posted November 6, 2010 My son's old desktop won't boot. Asrock MB, AMD Athlon 64 CPU, 2GB ram, ATI Radeon (Agp) GPU, XP service pack 3. On closer inspection i think it's failing POST. PSU, CPU and GPU fans all run, I think the drives are running, but no system beeps and "No signal" on the display. I've read loads of forums and tried a few suggestions;- Changed the CMOS battery, reset the BIOS by moving the jumper, unplugged everything and checked all connections, tried booting from a Start-up floppy, tried running without any ancilliaries (i.e. just PSU and CPU, with and without RAM). No beeps and no boot! I know the system's not worth much, but is there any way to check if the CPU or MB are dead without buying more kit and swapping things out?

Homer Posted November 6, 2010 Share Posted November 6, 2010 Does it have a chassis speaker? If not then you won't hear the post boot warnings. If it does and you have no sound it will be the motherboard or the PSU. I recently had a similar issue which turned out to be a fried PSU.

MrRalphMan Posted November 6, 2010 Share Posted November 6, 2010 I would say that this is probably the PSU playing up. Quote Link to comment Share on other sites More sharing options...
BK1 Posted November 6, 2010 Author Share Posted November 6, 2010 Sorry to be dumb, but how could it be the PSU if the PSU seems to be working? Quote Link to comment Share on other sites More sharing options...

Yes it has a chassis speaker, is there any way to check the MB without just replacing it? I'll try what Penguin said too Quote Link to comment Share on other sites More sharing options...
MrRalphMan Posted November 6, 2010 Share Posted November 6, 2010 I thought the same when it happened to me, all fans spinning up and leds lit on the mb. Ordered new mb, fitted it and it did the same. One new mb later and it all burst into life. Both mbs work, so I have a spare now... Ho hum! Quote Link to comment Share on other sites More sharing options...
DamanC Posted November 8, 2010 Share Posted November 8, 2010 PSU or motherboard. Try the PSU first as its the easiest and cheapest fix. The PSU may appear to be working by spinning fans up (the task that requires the least amount of power). Quote Link to comment Share on other sites More sharing options...
