Hi,
My PC (fitted with XP pro) is in no way recent, but with a few hundred Gb free on my HDs and 1,1Gb of Ram, a 1,1Ghz CPU (Athlon), it shouldn't behave like this one does.
I've been in contact with a French Forum which just goes round and round, telling me to clear the registers, to clean Toolbars etc. That has led nowhere.
Hijackthis has been used many a time and doesn't reveal any spyware.
When the problem occurs (that is generally when the DD led lights or when the performance is above 40%), the symptoms are as follows:

1. Cursur blocks on mouse movement at a rythm of about 1 sec.(then making jerky movements)
2. File copying blocks at the same rythm (jerky movements)
3. Sound (when listening to web radio) becomes echoed or sampled on a synthesiser, at the same 1 sec rythm.

These three aspects seem to be a memory problem. But unlike a "normal" memory problem, it occurs in jerks???
Can anyone help me solve this problem? It's been going on like this for many months. I still can use the PC, but now and then I go crazy with it.

Many thanks to anyone who could help me,

could be paging a lot. Press ctrl alt del and click performace have this running and use computer normally. When jerky behaviour occurs take note of page file useage and cpu usage then click on processes and see if there is something hogging cycles. Post back this information also might be worth running msconfig and stopping anything not needed from starting up with the pc. Might be worth updating all your system drivers also

It could be that the old Athlon is struggling with some of the tasks. Have you monitored temperatures? download and run orthos Download Stress Prime 2004 BETA this will run the cpu and ram hard. Also download and run everest |MG| EVEREST Free Edition 2.20 click computer and sensor and monitor cpu temps while running orthos.

the problem is the age of your motherboard Everest reads the diode on your motherboard obviously with this one it can not read it. Perhaps run orthos for an hour and check in bios straight away.When your suffering the stalls what load is your cpu under and what apps are you running that do it

you could run my patented OYB test. Run orthos for a good period of tiem with the side of your case off. After a while carefully touch the heatsink. If it makes you shout Ouch You B...... chances are its running to hot
