Since a couple of months my pc has been crashing randomly. Sometimes in Windows, but mostly while gaming. The system has Windows 98 and 2000 as OS installed, both fully updated with official updates. Did a memtest and it found no errors after leaving it on for hours. Also tried different modules and slots.
I can't figure out why the bios doesn't correctly detect the CPU at default settings; I have to manually set the fsb and multiplier. It did work for years that way though.
The CPU reads: AXDA2600KV4D.
Anyway, the specs:
CPU: Athlon XP 2600+ (Barton) @ 1921 Mhz (11.5x 166 mhz) FSB @ 334.1 Mhz
MB: MSI KT3 Ultra2 (MS-6380E), VIA Apollo KT333 (I did not see any leaking or otherwise damaged capacitors)
Memory: Single Channel DDR333, DRAM:FSB Ratio: 1:1 @167 Mhz
GPU: 3dfx voodoo 5 5500 agp (fully recapped)
Soundcard: Audigy 2 ZS
Storage: Scsi controller with 15k5 rpm HDD
Intel 1000 nic
Antec PSU (I don't have the case open atm, can't give exact type)
BIOS reads the following @ PC health status after 1 minute powered on:
Temps: cpu @ 21C, system @ 19C
Vcore: 1.664 (stable during stress test according to AIDA64)
+5.0V: 4.893 (drops to 4.65 using and according to AIDA stress test) <-- will check with multimeter, could this be the issue?
+12.0V: 12.106V (stable during stress test)
-12.0V: -12.071V (can't detect during stress test)
-5.0V: -5.127V (can't detect during stress test)
Bat: 3.296 (replaced)
+5SB: 4.921 (also can't see during stress test)
Lowering the FSB to 100 (default) fixes the issues, but obviously I don't want that.
Any ideas where I should look first? The motherboard has the latest BIOS available on MSI's website. Sometimes I can use the PC for 30 minutes, sometimes it's unusable. I also get random errors in Windows when starting programs (exception at ******* or something like that).
