I am running a winXP sys on an ACER PC. These recent months, my computer has been displaying a wierd behaviour of coming to a BSOD almost everyday, which give quite a few different stop errors. This symptom was absent when I first started using this PC. Over the past two years, my parents and my younger brother was the sole user of this PC while I stayed on campus and uses another laptop.
When I return home this vacation, I realised this problem and found it started half a year ago. It seems to occur randomly, mostly when the PC first started up (before Win gets to load) or while connecting to or within a few mins after connecting to the Internet. Sometimes several bsod will occur when the PC first boots for the day. Sometimes only one bsod occurs. Other times it seems fine. In any case, once the PC stabilises for the day, it remains okay till the next time we boot up the PC.
I have tried going through the google and found that it may be related to my USB ADSL modem or USB devices. I figure this as my modem also gives much trouble when I tried to dial up(couldnt connect). Yet I am not very certain as I didnt have alternative modem to test this device yet.
I am not very certain what is going on (hardware? software? drivers? virus?) and would appreciate some professional advices on steps to troubleshoot this problem.
Some of the examples of the stop errors I recieve(noted down) as summarised below:
- *IRQL_NOT_LESS_OR_EQUAL 0x000000D1 and 0x0000000A error code related to USBPORT.SYS
- *0x0000008E error code
Thanks and Best Regards,
