It has been quite warm here so laptops run hot and occasionally misbehave despite extra fans, etc. My ADVENT laptop started acting sluggish and locking up while running multiple apps, that it normally can handle. It started in the hot part of the day, but now can be anytime. Example, dl'ing torrents, streaming web-radio and surfing simultaneously. Task mgr cpu was very high use, but no process/app was using that much cpu.
The pattern is
lose internet connect>cpu use shoots up>unit gets hotter>screen freeze on browser>reset router>bsod
I thought it was a virus because one day I started the laptop and mysteriously my FFox wouldnt connect...setting was changed to use proxies
. And my IDE primary controller had been changed to PIO only, not DMA. Scans found nothing.
Then I started getting BSODs with this info:
0x40000080 (0x89D756C0, 0x89C1BA80, 0x80551388, 0x00000001)
I saw nothing directly related to these crashes in Event Viewer. I found that odd! I noticed alot of network access denied errors, nothing in the MS error reference link explained those. Also found event warnings regarding wscsvc service, TfFs Mon and TfSys Mon. I seem to have more services than before.
I used ProcExp and found the prob was Hardware Interrupts using 40-80% of my cpu. Research suggested a router problem and resetting the router does fix the Hardware interrupts problem, but then it BSOD, or it may run for a few hrs, then Hardware Interrupts goes wild again.
I ran TrendMicro Housecall/SAS/MBAM/CF/Saphos rootkit 2weeks ago when this first happened. A few minor threats may come up, but nothing major. Fans and cooling duct clean. Did have some video driver issues 2 months ago, but Driver Genius Pro sorted that out(i think). Advent provides no XP video driver for this model, and the ones I got from devid.info lasted almost a year before they developed problems. Maybe it is related, I don't know...
So now I am following your BSOD protocol. There seem to be no .dmp/.DMP files besides FFox crashes, nothing from this week at all. I've been BSODing at least twice a day. I dl'ed the dump analyser. But have no dumps to put in it. Yes, I changed folder view to see all files hidden and system. Nada.
Please advise me on next step.
Advent 5530 laptop, 2Gb ram, Intel Core2Duo 1.8GHz, orig. Vista wiped, downgraded to XP Pro sp3, MBAM Pro
