Let me start off by saying the specs:
Asus A8N-E Bios 1008 (date 8/22/2005) with Zalman ZM47J passive NB cooler
X2 3800+ OC 250x10 - HTT:4x - Stock Voltage
OCZ EL Platnium PC3200 2x1024mb CL2-3-2-5 at DRR416.6 (divider:166)
X800GTO2 Unlocked to 16Pipes and OC to 510/564
Seagate 7200.8 250GB
Antec Sonata II With Antec Smartpower2.0 450W And panaflo front case fan

The Problem:
Whenever I reboot the computer it would freeze on the black page saying about the primary/secondary ide and sata drives (forgot the name of this page), I know it's a freeze since nothing would respond (tried Ctrl-Alt-Delete and numerous other keys, the num lock and caps lock wouldn't respond on the keyboard too). It would force me to press the reboot button on the case and it would most likely not work. Sometimes (like 1 in 7 chances), when rebooting again because of being frozen, I would be able to boot successfully into windows by going into bios and just pressing "Save changes and exit" without changing any settings. I'm not sure if it's a heat issue since most of the time when i shut down the computer, and wait 10 mins, it would boot up successfully.

This problem started recently when i tried to change some settings in the bios then exit (froze at the page described above after exit). My system was overclocked like a week ago before this problem and was tested with dual Prime95 at 10 priority, small fft, for 16hours and with SuperPI. The times when i can boot into windows, it's very stable as i can play many stressing games for several hours without any problems. Could it be a memory problem, as i currently do not have any spare CDs/floppys lying around and i'm not able to run memtest86 but i have ran SuperPI at 16m and also two instances of Prime95 at the blend test. Kinda doubt it's the memory since there were no problems before.


Sorry if this is too long, I tried to be as descriptive as possible.

Thanks for any and all help, really appreciate it.

bump and also could it be caused by my passive northbridge cooler even though i have a 120mm Panaflo fan RIGHT beside it (it's located there because of the design of the sonata II case)

the bio settings were just overclocking, changed HTT to 3, upped the voltage, increased divider, and change fsb... the overclock wasn't even high, only at 2.6Ghz at 1.385 voltage. I also tried enabling CnQ, but then disabled it when i found out it freezes during restarts....

Might need to reset to default BIOS settings and start over with the tweaking. If you still freeze up with default settings, THEN you have a problem.

First, you did lock the PCI/AGP frequencies? I agree with resetting the BIOS. Cold boot problems are usually PSU related, since boot up is when you have the largest power drain. Make sure your power is equally distributed on the different lines, watch your voltages.

yea, the pci and agp frequencies are all locked. I'll try resetting BIOS later since i need to use the computer now and cannot have it unable to work...
