pfn_list_corrupt & other problems causing frequent crashes
Hi
I have been getting several messages in event viewer after one of my laptop's multiple daily crashes. One message is "The server (C7E39D60-7A9F-42BF-ABB1-03DC0FA4F493) did not register with DCOM within the required timeout." Another is "Hanging application iexplore.exe, version 7.0.6000.16915, hang module hungapp, version 0.0.0.0, hang address 0x00000000." Today, a new stop message occured 0x0000008e (0x00000005, 0xBF85GAAE....) Win32K address BF856AAE datestamp 49e87572. There have been several other stop messages and event viewer messages. I have run virus scans, malware, ram check, dskchk. Google suggested that the first message relates to a problem with McAfee. This is a 5 year old Toshiba A75 laptop running windows xp professional. It has 1 G of ram and the hard drive is about half full. Any recommendations? Thanks in advance Al Charbonneau |

You can look up the 8E error here. http://aumha.org/a/stop.htm ******* Examples of memory testers - http://www.memtest.org http://oca.microsoft.com/en/windiag.asp With memtest86+, test 5 is the most sensitive. And two passes may be enough, as for things like load sensitive faults, memtest86+ might not catch them. I find memtest86+ is good for "stuck" faults, such as a bad bit in memory, or a bad chip. Another test, which is a combined memory and CPU test case, is Prime95 torture test. It does a math calculation with a known answer. It also uses a lot of RAM while doing so. And that gives the ability to do additional testing, in a manner more stressful than memtest86+. So both programs have their uses, memtest86+ because it comes as close as possible to testing all the memory, and Prime95 stress test covers less of the memory, but does so with more stress. http://www.mersenne.org/freesoft/ You don't have to "Join GIMPs" when using Prime95, and can use it just for stress testing. An execution thread will stop when the first error is detected. I want to see a four hour run without errors, before assuming all is well. On a laptop, you'll want to remain on AC while doing the test. And elevate the laptop, so the cooling system can work at full efficiency. HTH, Paul |
