i have a strange problem.
some weeks ago i built my own PC.
after some trouble with a defective asus board, and infineon rams that would only run at 380mhz (instead of the promised 400), i now have a gigabyte board, and corsair twinx rams, everything works fine!
with the exception of one strange effect (not really a problem, but it makes me nervous!)
when i boot the computer up for the first time after it was turned of for some hours, the booting takes ages.
when the system is up, performance is bad (slow) too.
after some time, the system will "speed up" again.
and there is nothing that accompanies the speedup.
the system just gets faster and faster, up to the point where the "normal performance" is reached.
when i restart the computer after it has reached it's "final speed", the system boots up in no time.
when i restart the computer immedialtely after the first "slow" boot the system boots up still slow, but not AS slow as the first boot.
the funny thing is, all parts are equally slow/fast - except the BIOS POST (including memory test).
im running win2000 server on the box, and the "grey-bar" in text-mode is slow when cold, fast when warm.
the blue graphical progress bar in the win2k boot-screen: same effect.
the "preparing network connection" and "loading settings" windows (and all similar): same effect.
i've already checked my rams with memtest86, 12 hours @420mhz (just for testing) -> no error.
now running @400mhz, should be fine.
finally some specs on my system:
board: gigabyte, i875P based (must lookup the exact name if it matters)
cpu: P4 2,6C (2,6Ghz, "FSB800")
ram: corsair twinx 2x512Mb at 400Mhz, dual-channel
psu: some 460W enermax thingy
system-disk: stripe-set with 2xWD Raptor (10.000rpm, SATA) - driven by the Intel ICH5 SATA raid-controller, stripe size 16K.
other disks: 1x 80G Seagate Barracuda + 1x 120G Seagate Barracuda
cd/dvd: 1x toshiba cd-rom, 1x NEC 1300 dvd-writer
gfx: saphire radeon 9600, passive cooling (zalman, not the original passive cooled version but self installed).
os: windows 2000 server, SP4 + various hotfixes
i think it might be some thermal problem, but i just can't figure out what or why...
it the effect is "normal" i can live with it, i just don't like the idea of something strange going on that i dont understand - because as long as i don't know the cause it could be *anything* - including things that could cause some serious damage/data-loss
if you need any more information, just ask.
i would be very grateful for anything that could help me understand this
