Just built a "new" pc (spec below) from some brand new components and some old ones. When i power up the unit all the fans and lights come on as they should but then it just dies and the only way i can get the pc to power up again is to pull the kettle lead from the back and plug it back in again.
SPEC
AMD Athlon XP 3000 (old)
Aspire ATX-AS420w PSU (new)
ASRock microAtx Motherboard K7541 (new)
2x 512Mb PC3200 DDR Ram (1 old , 1 new)
LG 512 DVD Rw
Western Digital 80 Gb Hdd
I also have an Ati Sapphire Graphics card and a creative live 5.1 sound card, but havn't installed these yet as the new motherboard has onboard sound and graphics.
Please help this is really starting to pee me off !!

If you're not hearing any sounds from the Power-on Self-Test, chances are high that either your power supply is fried or is not adequate to drive the hardware. Is the power supply new?
I wouldn't run any system with less than a 400W power supply these days.

I think I would be inclined to agree with the rest, that your PSU is gubbed, its either that or its not liking something attached to the IDE bus, perhaps an incompatible hard drive, or the jumpers set wrong, possible but unlikely. You mention that one of the RAM modules is old, if the system RAM has a problem it would shut down by itself, also are you sure the motherboard has the right ZIF socket for the older CPU you installed. I'm considering building a new base unit, but everything will be brand new except the HDD, less chance of snags that way, and the fact I'm an IT Technician might also help! Best of luck, I hope you get to the bottom of it, shame after spending all that hard earned!

Well a few things to check...( I don't agree that this is a power supply issue) 1. Do you get beeps when powering on? No? then do the following:
A. make sure the Processor and memory are well seated. Also make sure the heatsink and fan are contacting and connected.
B. Remove any non-critical card. Looks like you don't have any.
C. Try only one memory module, then the other, then none...just to see how the bios beeps are affected.
If you are getting beeps, then the motherboard manual will give you the keys that you need to proceede...
Also, reseat any cards.

well done on your build,i did one this week and its good fun,but not if the blasted thing wont start
i have noticed that you are using mixed parts,and thats ok,apart from memory,i would be very careful when mixing ram as this can cause stability problems,even if they are exactly the same freq,speed...try just 1 512mb module and see if the system stays on,with a bit of trial and error you can see if it is a memory module incompatibility issue
the amd athlon should be fine,you did check for scorch marks on the pins and for any bent pins
another worthwhile check should be 1)check the front panel connectors...there should be a few hdd led,pwr led.reset and if you need to know the way they go in check the motherboard manual 2) hard drive ide cable 3)all 5v power plugs 4)cd rom ide cable 5) atx power plug
try using another psu....it could be a faulty psu,this happened to me a while ago,but my money is on the memory module,,try the new module and i reckon it should run fine,then trade the old module in for a new one....this should get you sorted
any probs ........let me know
good luck

Sounds like a bad connection between the power supply and motherboard.
Check all connections are in place fully

I think you should check the CPU fan and make sure everything is seated properly because it sounds like automatic shutoff is operational this is to stop your CPU frying. The thing with computers is that everyone thinks it is easy to build one but I make a living out of correcting errors : )

Possibly weak insulation or a weak chip. Also, check for loose connections. Do take a scrutinizing look at the UPS, too.

if the bios beeps like mad beofre cutting out you forgot to put thermal paste on the bottom of the fan and the cpu is overheating,
