My entire system is oftern slowed down to a crawl. I think it's a deferred procedure call thing. If I open Process Explorer at start up I can tell how my machine is going to behave. Sometimes it starts up with 40-60% DPCs in which case I need to restart (doing anything else reduced the machine to a crawl as above and makes the DPCs leap to 90% such that WMP only gets <0.5% of CPU time). The machine is fine for browsing, word processing, etc but whenever I try to load something more complex like WMP or a game, the whole machine slows right down to a crawl. By this I mean that floating windows leave a trail, the mouse pointer jumps centimters at a time, etc. WMP plays files at two or three frames every few seconds (the sound is fine) and games get all of 1 FPS.
Once the program is terminated (usually I'll have to do this via task manager, which also runs at an enourmously slow rate) the system still only runs at a crawl to the extent that if I move a window whilst I type this it will leave an impression on the screen for a few seconds.
In Task Manager, or process explorer my cpu cycles are at 85% to 93% at all times with 'System Idle Process' taking up most of the cycles (services.exe, firefox.exe and a couple of others periodically stick in 7-20%). Process Explorer lists the same, with 80-100% deferred procedure calls, 1-5% idle and the same smattering of everything else. I can only assume from this that Task Manager lumps DPCs in with System Idle.
At other times as now it starts as normal, with 0-3% DPCs and a mostly unused/idle CPU. I can open programs and watch films in WMP without issue for a while, but the longer I keep the machine on, the higher the percentage of DPCs are used each cycle and the slower the machine becomes.
I'm running on a A64 3000+, 1gb, 6800GS, XP SP2 rig which normally runs as smooth as silk. This problem only developed yesterday.
I've not been downloading anything suspicious recently; I've run adaware and norton AV (both using the latest definitions), which find nothing. I just can't see anything that's causing this.
I can't for the life of me figure out why my machine is so unwell. It seems like a trojan, but I can't find anything. The only other thing I can think of would be a hardware conflict as I've recently installed a new sound card and monitor. I can't see anything obviouis in the hardware manager though. I'm thinking of resorting to a clean re-install, but I'm working on a new unattended installation and I'd like to do it with that when I finish it (which I can't really do with the system as it is).
Anyone ever seen this before? Where do I go from here?
