Hello, Im trying to fix my sis PC but I have one problem, first her PC specs: Pentium 4 3.4Ghz 478 sockst with Thermaltake Sonic Tower with 12cm Fan. -Idle: 34ºC Full Load:47ºC 2x512Mb DDR DCH 400Mhz AGP 1950GT 256MB idle 49ºC FULL LOAD less than 70-72ºC + VRM has an addictional cooler.not like 1950pro and his vrm problems. NOX Urano 500W PSU, [new] Gigabyte 8IPE1000-G With fresh windows xp install, with 7.6-7.9 catalyst drivers I've retarded fps. I was testing several games, they run great, I've stable high fps but for only 30seconds+-, then huge fps lag, like 10fps or less,after 15 seconds all is back to normal. happens again and again..... I tried with her old Radeon 9600Pro, it's the same. One thing I know is that the chipset cooler is ultra hot, like untouchable for human hand for more than 3 seconds...maybe changing it could resolve my problem... Any ideas? thanks.
