Sporadic OS Freezes and Unexpected Reboots

Greetings;

First, I am a hardware novice (I'm much better when it comes to software).

I may have 1 problem, or, 2 separate problems. I will try and explain the symptoms as best I can.

I thought at first these symptoms might occur do to a corrupted operating system (I'm running Windows 2008 R2 Standard SP1). Last Saturday I performed a clean install of the OS. The symptoms continued after the clean install, so, I doubt the operating system is at fault.

1. This symptom began far and few between and has progressively become worse as of approximately 10 days ago. My mouse and keyboard freeze unexpectedly. By freeze I mean neither the keyboard nor the mouse seem to have any effect on the computer. CTL-ALT-Delete does not have any effect. I press the hardware reset button in order to reboot. About as often as my computer keyboard and mouse freeze, however, the computer will unexpectedly reboot as if the hardware reset button were pressed. This sudden reboot does not seem to be tied to a specific application.

2. This symptom involves Internet connectivity. The symptom started more progressively than the first symptom. As of today, about 50% of the time I wish to go to a web site, or, download a file, the connection between my computer and the Internet fails. My solution is to unplug my router and plug it in again. After the router talks to the cable modem all is well until the next time.

My hardware layman brain is thinking this may be a power supply issue. The computer was built in 2006 and is almost never turned off. I have ordered a power supply tester from NewEgg Software which should arrive tomorrow (Thursday, June 6th).


Any assistance you can offer is greatly appreciated ... David

I was thinking more on the lines of Memory faults. These usually lead to erratic and sporadic weird behaviour.
If other components fail (e.g power supply, Harddrives or Mainboards) the Server usually just bluescreens or downright flames out.

Is it a Server hardware or client hardware?

I'd run a memory checker over it. Some Server Hardware manufacturers offer bootable diagnostics tool such as HP's Smart Start CD.
If it is a client hardware, you could use memtestx86 which is a bootable iso that you could run from a CDRom. It runs checks on your memory banks and will be able to tell you if there is a fault there.

Hope this helps

Also sounds like symptoms of bad capacitors.  Your computer is 2006 vintage which is prime for this problem.  See this link for more info.

It can be fixed but requires desoldering the capacitors and soldering in new replacements.

Greetings;

I downloaded and created a bootable CD for memtestx86. The test ran for approximately 50 minutes with no discernible errors reported. I don't know if I should have let the test run longer or not. Perhaps you can advise me.

I removed the 4 2GB memory sticks and using compressed air ensured there was no dust in the memory sockets on the motherboard. I also blew off the memory sticks and reseated them. I didn't replace the sticks in any particular order, so, there is a chance some sticks went into different slots. The sticks are all identical however.

I haven't visually checked for bad capacitors as yet. The power supply tester will be here tomorrow and I will examine the motherboard for signs of "oozing crap" around capacitors ... LOL.

Thank you for suggestions and help so far ... David

when running a memtest  leave it running at least for 1 full pass - better 3 passes
but i suppose that's not your problem
freezes do come from many sources - mostly hardware though
in order to know how to diagnose -  How often does the freezes occur ? evry 10 minutes - or after 3 hrs?
te be sure it's hardware - if they happen frequently - boot from a live cd, and test for 2x the time between freezes (at least)
if no freezes -  the problem stems from software, and a fresh install should fix it (or a factory reset)

Greetings;

I performed a clean install of the OS 9 days ago. Using compressed air, I blew out the dust bunnies inside the case. I removed the memory sticks and blew out the memory sockets. I went to the ASUS sight (I have an ASUS P5WDG2 WS PRO motherboard) and downloaded and paid for a utility called Drive Tuner. I installed all drivers it said were out of date or were not installed.

The freezes and sporadic reboots continue to happen. Now, one or the other usually occurs at least once a day. The last freeze which occurred about 12 minutes ago left a footprint in the Event Log:

"The following fatal alert was generated: 48. The internal error state is 552.".

The Event Log recorded the following 2 entries from previous freezes/unexpected reboots:

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Bus/Interconnect Error
Processor ID: 1


And

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Bus/Interconnect Error
Processor ID: 0


After another freeze/unexpected reboot the Event Log reported:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000124 (0x0000000000000000, 0xfffffa80071a0038, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\Minidump\060913-34991-01.dmp. Report Id: 060913-34991-01.

Question: Would replacing all memory sticks be advisable at this point? Or, would a different action be advised?


Much thanks ... David

Greetings;

I understand and agree my symptoms are likely to be hardware or possibly driver related.

I use a backup and restore program called Retrospect. Without fail, when I run Retrospect and request a task which is either medium or long in duration, my system freezes. I have written to Retrospect and described my symptoms about 10 days ago. They replied it is not their software. This may be true, however, if memory serves me correctly, Retrospect does provide their own drivers (at least in part) to read and/or write to devices.

I am writing Retrospect again to update my symptoms with them. Their software may not be at fault, however, if their drivers are interfacing with hardware on my computer, and, my hardware is at fault, Retrospect may be able to shed more light on this.

I appreciate your patience. Yes, I do plan to invest in a new computer when I can afford it.


Much thanks ... David

check also the cpu and other temperatures -  install speedfan to monitor :

also - look for bad capacitors on the mobo : c

My apologies for not responding in a more timely manner. I have a newer computer.

I would like to award nobus the points for sticking with me on this issue.
