Instability, hardware MB/CPU/PSU ?

[Gerry Abbott]

Hi all,
Im having problem with stability. Getting the stop screen with a variety of
erros. Was overclocking my CPU 100x4 -->119x4 FSB, with no problems. Then
got deterioriation in stability, not associated with any new hardware or
software installation. Now back to stock speed, but still problems.

Heres what ive done.
Tried alternative 3200 ram, replaced existing 2700.
Tried different video card, ATi 7200 in place of 9800xt.
Swapped HD, with 98os, in place of XP, all other peripherals eg cd rom,
removed.
Also tried hooking up a 250watt PSU, and running dual PSU, the MB/Vid card
off the 250w, with all else on the QTec.

And in all cases was still getting crashes, to a slightly greater/lesser
extent.


So think Im down to three possible sources of problems, all hardware.
CPU (its a 2.4P4, 400fsb)
MB (its a P4S8X-X, with on board lan and sound)
PSU (its a Q-tec, dual fan, 450w)

Since I dont have any compatible replacements for these, I cant 'swap' them
out. Would like some advice as to how to progress to narrow down the problem
further.

Thanks in advance

you have narrowed it down.

now replace what you burnt and don't agressively overclock anymore and if you do decide to overclock watch for little niggling signs of pushing it too much like random instability issues.

sorry but without new replacement hardware you aren't gonna be able to narrow down further so i'd say a new mobo/cpu combo in your near future

I did watch for the niggling signs when I orignally overclocked a year ago.
System has been very stable @119x4FSB until recently. I upgraded to XP,
added a new Vid card, and it worked fine for a week. Then out of the blue,
instability, then more, and I gradually pulled back the OC, to where i'm
now.

Not convinced its the MB or CPU, but agree, that i cannot narrow down more,
unless i try replacement parts.
