Perplexed!!!!

crazy <-- trying to build a computer...

 

In short, my problem is that I bought all my parts (new retail) put my computer together and it doesn't work.

 

I bought a Athlon XP 2600+ and put it on an MSI nforce2 IGP mother board, with 512mb Kingson RAM, in a case with a 350w power supply. It wouldn't even start up(cmos) most the time and when it did it would reboot constantly before I could do anything. So I figured it was the power supply, but instead upgraded to a MSI k7N2 Delta motherboard. And Of Course there was the same problem. So I bought an new Aspire 500w ATX/12v ps and it wouldn't even power up. When t finally powered up it the D-Bracket LED tool hung on detecting the processor.

 

When I put in the old 350w power supply again it consistsantly started up detecting the processor (though it still rebooted off and on).

 

Is it the processor or the power supply or what?

Ram, or the CPU is getting hot

 

Go into the bios and monitor the temps when you first boot

Now even with the 350w ps there is a blank screen and no beep.

I'm thinking its the processor now, but I'll probably send back it all.

Is there a chance that the products I'm using for some reason aren't comaptible (though they should be) or does it sound like the products are faulty?

check for any jumpers that need to be set on the mobo to tell it the FSB of the AMD chip....

 

also a 350w is not very strong for todays cpu's. so use the larger one - if it starts up then shutdown it means you PSU is not good enough.

 

also - does your mobo handle that cpu... and that ram - alot of mobo makers are picky about what ram you use.

Thanks but I tested it on an expensive 500w psu and it wouldnt power up. Also my motherboard is recommended for my processor on the AMD website. And my motherboard jumpers were set to 100MHz safe mode. I also tested it with ram that worked on somebody elses MSI board and it made no diffrerence.

 

I am still lost, so any other ideas would be great!

Things to try:

 

Take the processor out, check to see that it isn't cracked (too heavy handed installing the heatsink), or that it looks scorched (fried CPU)

.

Reseat the processor, apply fresh heat transfer compound (Arctic Silver or the like). Make sure you've got the heatsink on the right way round, that it's seated properly, and making good contact with the processor.

 

See if that works. If it doesn't, you've probably got a dud or fried CPU - time to get another one!

 

Try removing all add-in cards - even the graphics card if the motherboard has an onboard graphics chip. It may be that one of those is causing the motherboard to fall over.

 

Hope this helps

Best ideas yet, but I was one step ahead of you. I took the CPU out and it looks to be in mint condition. So I applied new compound and put it back in, but it still wouldn't register.

I've sence packaged it up to send send for a replacement. Just to make sure I sent everything else back for replacent also. But who knows with my luck I'll have the same problem with the next batch of parts.

Oh yah...I build computers in increments for troubleshooting purposes, so there were no cards installed just video and floppy, and I tried it without both (even including diff. cables and video cards).

 

Thanks for all the replies
