Hi!
An older PC (Q6600 + P35) has this problem: Every now and then (once a week or less) it freezes right after power on or in the first few minutes after it.
It worked fine in august (the weather was very hot) but then last Thursday (when autumn weather kicked in) it happened. After Windows loaded it froze and a continuous beep started. After reset it hung during POST.
On next try it booted, so I started Memtest86+, where it reported a few RAM errors, in and only in test #5 (Moving inversions, 8-bit pattern).
After about 30 minutes all symptoms disappeared and the PC worked fine for the rest of the day.
First I suspected the temperature: it worked fine in august (hot), and give problems in september (cold weather). Also: problem when PC is cold, problem gone after it warmed up.
But later I could not reproduce the problem. I even left the PC on the balcony to cool down to lower temperatures, but it never malfunctioned after the first case.
This is not a new problem. It happened every now and then before. I replaced the PSU, but it didn't make a difference.
I mentioned the recent event separately, because I decided to sell the PC and cleaned it up (in august). Replaced the CPU thermal grease etc.
So what to do? How to find the root cause?
As mentioned, I am selling the PC, so I want it to work.
HW details:
Asus P5K-E WiFi motherboard (Intel P35 + ICH9R)
4 x 2GB RAM (DDR2-800)
MSI Radeon 6770
1 SATA HDD
1 SATA DVD-RW
I removed 2 RAM sticks during the problem hour and the problem persisted (RAM errors).
Regards,
David
PS: The LAN module on the motherboard does not work. It is not even detected as a device in Windows (or Linux). I suspect it broke after lightning strike in the DSL modem. The modem had to be replaced. Otherwise the motherboard looks fine (the capacitors look normal).
