Toshiba Satellite 1115-S103 not booting at all - totally stumped - any ideas welcomed Hi everyone, I left my Toshiba Satellite 115-S103 with the Norton Antivirus running when I left the house. I came back and it had completed and said there was no viruses. I didn't touch the laptop, I just went to bed. When I got up the next day the computer wouldn't come back to life, so I killed the power and tried to restart it. It wouldn't boot at all. No HDD activity at all. About an hour later, after I had just left it alone, I tried and it booted up fine. Then I restarted to see if the problem had solved itself, and it wouldn't boot. Awhile later I booted it and it didn't get into windows, it stopped at this screen. Phoenix BIOS 4.0 Release 6.0 opyright 1985-2001 Phoenix Technologies Ltd. All Rights Reserved BTK0 BIOS Version V1.20 CPU = Mobile Intel (R) Celreon (R) CPU 1.50 GHz 512M System RAM Passed 256K Cache SRAM Passed System BIOS shadowed Video BIOS shadowed Fixed Disk 0: IC25N020ATCS04-0 ATAPI CD-ROM: MAT****ADVD-ROM SR - 8177 Mouse initialized ERROR Resource Conflict - Allocation error static node #0D Press <F!> to resume, <F2> to Setup Press [F2] for Setup, Press [F12] for boot device selection menu Then the computer froze and I couldn't get passed this screen, so I restarted and had the same problem of it not booting at all. A while later I got into Windows, (just tried booting and it worked fine), and it was running really slow, so I checked to processes running and there was an Isass.exe running that was using up alot of CPU power. So I looked up the Isass.exe and some ppl say it's a virus and others say it might mean I have a virus, the thing is that Norton had just run and it said I was clean. Now the laptop won't boot at all, there seems to be no HDD activity, and I can't do anything with it. If anyone can help, please post a message. thanks, Aaron Edit: I noticed it starred out part of my message there, those stars are * * * * in the error message. Edit: I just remembered one more thing. When it finally started up again I noticed that it had done an automatic Windows security update. I don't know if that has anything to do with it, but it's another thing I noticed. Edit: new developments: Well it got to the error screen again now, but the Resource Conflict error wasn't there, it was "0280: Previous boot incomplete - Default configuration used" and the very last line about the [F2] and F was gone. Now it's just doing the same thing again and not booting at all. With all my reading I'm beginning to suspect that BIOS is not running POST all the time, or BIOS isn't working or something. Can anyone tell me if this makes any sense given what I have explained is happening? Edit: Well new developments....I left the laptop overnight with the battery out and the power supply unplugged. I came back to it in the morning (8 hrs later) and plugged in the AC and it started up no problem. What's going on!!??? I haven't tried restarting it again because I've been running checks on it, and it seems to be working just fine, but I'm sure as soon as I shut down, it will be just like the other times and not restart for me. Edit: Well i've heard a trick about freezing a stick of RAM to get it to temporarily work. So since I started thinking that it is some type of hardware problem with my laptop, maybe cooling it alot would help it get going. The problem is only with booting, once it is booted it seems to run as long as it wants. Although I haven't tested that theory thoroughly (only a bit over an hour or so). So I didn't want to put it in the freezer and damage the LCD and I didn't want to take the LCD off, so I put the laptop in the fridge for about 10 minutes. When I took it out, it started up no problem and is now running again. I don't know if it had to do with it cooling way down, or what, but that seems to have allowed it to boot. I'll try it again to see if it's consistent. Edit: Well I tried the fridge thing again, and that's twice now that it has worked fine after being in the fridge for 10 or 15 minutes. It seems to be consistent that if I shut it down, then put it in the fridge, it will start up fine.
