Computer Dc5100 Xp
My computer seems to be fried, help me diagnose whats wrong?
Windows XP SP3
DC5100 sff
Geforce 9400 gt pci card
It had been stuttering on start up
When I press power, the bells and whistles gear up and then die down
The power light comes on, but the hard drive light does not flash
I do not get BIOS
It froze during a few hour idle session, I think only google chrome was running on it.
I'm thinking the CPU or mombo, I've heard it may be hard drive failure, but I don't think that is the cause of not having BIOS. I've also been told its a possible PSU failure, but LEDs on the mombo still work
Is there any way to distinguish between CPU and mombo failure?
If it isn't those, what is it?
Please explain your answer, if you just say "PSU DUN IT" you're not going to get 10 points
With no BIOS screen, it's the PSU, motherboard, cpu, video card or memory. The hard drive doesn't factor in yet.
Try the easy stuff first. Clean any dust out of the PC. Remove the video card and memory. Make sure the contacts are clean (a pencil eraser can remove minor tarnish easily). Reassemble and try again. Maybe it was a bad connection.
Still no luck? Before chasing down expensive diagnoses, if this is a 3+ year old computer, replace the CMOS battery (usually a CR2032) for ~ $4 and see if that fixes the problem.
The computer should beep at you if it detects an error on startup. Those beep codes can be used to identify the faulty component.
If you have a voltage meter, check the connectors on the PSU. There are several different voltages being generated, it only takes one of them to fail and cause a problem.
Inspect the motherboard, especially the small cannister like objects (capacitors). If any of them are burn or partly melted, the motherboard is the likely culprit.
It's rare for a cpu to fail. Drives tend to be the first devices to fail (due to moving parts), but power supplies are the most likely electonic failure, especially if you don't have the system on a surge protector.
