I've been having a problem with intermittent, seemingly random lockups. It's a total freeze with no BSOD, no error messages, nothing. Screen is just completely frozen, CTRL+ALT+DEL has no effect, and even after hitting reset it will reset, but not POST after the reboot. Sometimes when this happens, even the On/Off button does not even work, and I have to flip off the switch to the power supply.
What's most strange is the TIMING of the lockups. I have run the Memtest 2.8 with no errors, looped the Sisoft Sandra burn-in test non stop for dozens of runs with no errors, and I've never encountered a single lockup while playing 3D games (Max Payne, Serious Sam, Wolfenstein, etc), or any games for that matter. It seems that no matter how hard I try to stress-test the system, I can't even CAUSE the lockups to occur.
However, ONLY time I have encountered these lockups is 1) while doing mundane tasks like web surfing or typing in Notepad or 2) while the system is idle; i.e. it locks up in the middle of the night.
Any suggestions? Why are the lockups occuring ONLY when one would least expect them? Here is my setup:
-K7S5A with "XP" sticker
-Athlon XP 1600+
-Running at 133/133 mhz
-300W Sparkle PSU (this PSU worked fine for over a year while powering a MUCH more fully loaded system than this one)
-two 256 meg Crucial PC133 SL2 DIMMS
-Visiontek Geforce 2 GTS-V
-Using onboard sound, LAN
-Vantec CCK-6035D cooler using 3-to-4 pin adapter
-Enlight 7327 case
-Newest 12/15/01 BIOS
-Dual-booting between Win98 SE and WinXP (problem is the same with both OS'es)
-Chipset heatsink has been removed, lapped, and reattached with Arctic Silver
-Case is well cooled with two 80 mm fans, HD cooler, and PCI slot cooler
-All PCI slots are empty
-All ACPI/power-management is disabled in BIOS and in OS
As for my voltage and temp readings, here they are:
Vcore 1.488
VCC 2.5v 2.48
VCC 3.3v 3.28
VCC 5V 5.053
+12V 11.968
SB3V 3.408 -12V 11.311
SB5V 5.026
VBAT 3.408
CPU fan 7000 RPM
SYS temp 31 degrees
CPU 38 degrees
All drivers are completely up-to-date for all components. I'm also experimenting with different driver revisions of the Detonator drivers, but so far I have had no luck.
One more thing: several times when I moved the case while the PC was on (not major shock, just moving it around), the lockup occurred immediately, which suggests that there is some kind of physical problem. Is it possibly a grounding/short issue? I did not use any special screws, stand-offs, etc while installing the motherboard, since the case (Enlight 7237) does not appear to need them. My other system using the same case has worked fine (Asus A7V MB) and was installed in exactly the same way.
Any help would be much appreciated!!
Thanks.
