Hey guys let's see if you can help because I have tried almost everything I can and can't find a solution to my prob. When I'm using my pc with some rendering app, may it be games , emulators , even years old abandoware, I'm running fine and then the pc starts to loose frames and completely stops for a few secs and then moves on until eventually that happens again and it can happen quite often. I have a P4 1.5 a Compaq mobo with agp 4x and 384mb pc 133, an SB audigy gamer card and a radeon 9600 XT 128mb. I used to ghave a different sound card when the proble started a SB Live Value, and the comp now does the same when playing hardware accelerated midi, I've also tried using my old GFX card a Geforce 2 MX 440 64mb, and the chocking occurs less often but still happens. Bear in mind that I got to use the Radeon perfectly for some time before this started to happen. It ain't the memory because I tried with different stick it ain't hte hard drive cause i have 2 and formatted one and installed windows in both a still the same sh*t happens. Apparently is a pagination prob, I'm thinking a prob with the cpu or some part of the mobo the ram slots or the agp slot. bear in mind that this started to happen after leaving the pc on for a few days. If anyone has an idea of what could cause this issue.
