I have a Dell GX280 PC where if a screensaver launches (made with v5.25 Pro), the CPU use goes up to 100%. The screensaver only comprises a single JPG at present (don't ask!)
The PC is running XP SP3 x86 and has an Intel 915G chipset which uses the driver ialmrnt5.
I used userdump.exe to grab a dump from the screensaver file and the stack shows:

I don't know if that provides a clue as to what's going on.
I put on the newest graphics driver that Dell provides which made no difference and ensured DirectX was up-to-date. I tried the reference driver from Intel's site but it refused to install.
Has anyone seen this before? I will be looking out for it on other PCs of the same model to see if others are affected.
