 |
|
Hello
A friend asked me to format and re-install XP on PC with an ECS RS482-M m/b,
Athlon 64, on-board ATI Radeon Express and
512mb of RAM. It was starting to run slow but with without random crashes or
other problems.
The format was so long winded I had to do a quick format and the XP
installation took 90 minutes. I suspected the h/d was faulty and replaced it
with
a known good drive. This made no difference to the install time.
When I finally got XP running task manager CPU performance is running
permanently at 100%. This is with no other programs open and no internet
connection.
The only way to get some of the drivers on was to hook up an old PCI video
card to take some load off the CPU but the task manager still reports 98%
under the
System Image name in Processes.
I have checked the Bios and all looks OK to me, resetting the defaults or
tweaking makes no difference.
The system sits there perfectly happily with the desktop displayed with no
crashes, blue screens etc so I reckon the PSU and the memory must be OK
and the system temperature is only 47C.
I have been building my own systems for 10 years and repairing family and
friends PCs so I reckon I'm fairly knowledgably but this one has got me
beat.
Has anyone got any suggestions / advice befor I bite the bullet and swap out
the m/board.
Thanks for any help.

Did you check the Processes tab in Task Manager? What exactly is taking all
of the CPU time? What is System Idle Process showing up as? I'm presuming
it's a single core A64?
I did once have an issue with a CD/DVD drive being faulty, and causing
massive wastage of CPU. Disconnecting it fixed the problem.

Does look like a high interrupt load due to faulty hardware.
I'd definitely run it loose on the desktop before swapping the
motherboard, basically because you have to take it out to
swap it anyway. Not very likely to be the problem, but its
never possible to predict what can get shorted, it might be
something that generates a high interrupt load. |

Has the CPU heatsink become loose or detached? |

Yes of course you're right. Sorry, how dumb of me. |
