Re: [H] Dea CPU?

2005-06-02 Thread Neil Atwood
Hi List,

My main desktop machine failed to start up this morning.

System is a P4 3.2Ghz - about 15 months old, built by me.

Symptoms:
Mobo appears to power up OK. (a Gigabyte GA-8KNXP) - Power LED on board is
lit, RAM LED is lit, IDE devices go through their normal initialisation.
All fans are spinning, heatsinks are clear and clean

But no video, no error beeps, nothing! Screens report 'no videi signal'

Swapped out video card - no change.

Reseated RAM, no change.

My curent guess is dead CPU... but is there anything else obvious I should
be checking before I RA the CPU?

Thanks

Neil A.
Sydney Oz.

Unless you are overclocking, or have been running it without cooling, I 
would say the CPU is the last thing I would suspect. Remove everything 
except video card, CPU, one stick of RAM and see if it will POST. If it 
does start adding things back, one at a time. If it won't post, swap out 
the RAM with known working RAM, then the video card with any old PCI card 
that you know is good. Then the power supply, then I would suspect the 
motherboard, before the CPU. Bad CPUs that aren't made bad from abuse, are 
extremely rare.

Just because the board LED lights; doesn't mean the board is 
functioning. I'd start with that.

 No overclocking here, and cooling is good - and I agree, a dead CPU under
 normal conditions is pretty rare.
 
 The video card is the only card in the system, and I've elimiated that as
 the problem.
 I've attempted booting with all drives - HDD and optical - disconnected.
 No change.
 I don't have any appropriate RAM modules on hand, so that is a problem.
 Smae with PSU. But I can see the value in eliminating those as the
 problem...
