1. System will halt every once in a while on the desktop. Regardless of the programs open of the systems usage, the system appears to be locked up but when you Alt Ctr Del the XP menu will come up. The system then will return to normal operations in about 20 to 40 seconds like nothing ever happened. Event log shows nothing unless I rush it and try to log off the machine then I will get software error entries and fault bucket entries in the event log (error logs will consist of any software open at that time).
2. System will hesitate when switching tasks on the desktop, for example MSN Messenger will take 3 to 7 seconds to switch over to the next chat windows, this holds true with browser windows, even software like Office XP word for example. There are instances where it won’t change at all; you have to click several times. Note this only occurs when clicking on the task bar to switch from window to window or task to task. But when Alt Tab is used the switching process is usually flawless.
These two problems make me believe that the hardware is somehow defective. With reason being I have never experienced this with any platform before AMD or Intel based and so far as DDR and RD based either. The only difference with this system from all others I have worked on is 32bit RDRAM. Since I have 3 P4T533-C's running 1.6's over clocked to 2.13 with RD 800(16bit) and none of them have ever caused such things.
Also to be noted I have replaced the motherboard 3 times to get this current revision of the motherboard (active cooling on Northbridge and higher quality power circuits) thus to run the 2.53 more stably. I have also replaced the power supply 3 times with the new one at 400watts (all rails 3.3, 5.0,12 are all good) which makes me rule that out. The video card has run in 3 different machines which draws me from concluding its at fault. The sound card has been in another machine as well run which makes me rule that out as well. Hard drives don’t seem to be to blame as well since they are new and I have had this problem before I purchased them and created a RAID 0 with them. Network card has been interchanged to another machine with no problems. The CPU as well has been placed in the P4T533-C's without any problems as well.
So through my own research I have been left with either the memory or the motherboard. Memory doesn’t strike me too much as being bad since I would have a blue screen every once in a while. But the motherboard is the only constant thing that hasn’t changed other than simply replacement due to RMA.
Well I leave you with this gentleman in hopes that you can bring light to the situation. If you need any other information regarding the system without actually physically having it please don’t hesitate to email me.
Heres a thing to do, try having taskmanager open and up on the screen while doing stuff, and take note of cpu activity AND kernel cpu activity (the red line). See if anything unusual happens during those periods of "frozen-ness".
Theres a chance it could be some background task or device/driver conflict going on. who knows?
