Everytime I leave the PC on overnight to download files, it shuts itself off I cant turn it back on in the morning. Now at first I had the system standby set to 30 minutes or something. But I also tried taking all power managment settings off, like standby, hibernate, etc. But the PC still shuts itself off and wont turn on in the morning. It wont respond to the mouse or keyboard or the power buttons on the keyboard. So i hit the reset switch and it reboots. After windows loads i get the message "the system has recovered from a serious error (or fatal error, cant recall exactly right now)" It give me the option to veiw the error log. After I click OK to get rid of the window everything is fine untill the next time it happens. Any ideas would be appreciated. SOME INFO ABOUT MY SYSTEM: Windows XP Pro. I put in a new motherboard and had problems with getting automatic standby worknig so i fixed it by going to BIOS and changing the ACPI Suspend Type from S1 to S3. Motherboard is Gigabyte GA-8IPE1000-G Im vary stopid

Hmm, thats a pretty odd problem. Now I've gotten similar warnings like that, except my system doesn't shut itself off... it runs really really slowly and then when I try to reboot it, when I get back to desktop it gives me that "Windows has recovered from a serious error" message. I tried a different hard drive with a clean OS and it fixed the problem. If you have a spare drive, put that in and try to intsall an OS and boot of of that. If you don't, try to do a system restore to a previous point. There may be a program that is conflicting with the hibernation/power management settings that you've tried to disable. If this were to lead to possible hardware solutions, I'd say look at your power supply first, then maybe ram.. and motherboard. Thats a pretty wierd problem though. Flashing and updating the bios might not be a bad idea, if you know how to do it (which I don't). -BornChaos

If you've turned off all the ACPI power management stuff so that it shouldn't suspend itself or hibernate or whatnot, then a BIOS update does sound like a good idea. That's where most of the APCI power management stuff is set up. To do this, go the website of the maker of your system board (or OEM, if it is built and sold by someone like Dell), and search for BIOS updates for your system board. Download the latest, and follow the directions there to put the BIOS flash on a floppy. If you don't have a floppy drive, then there should be directions on how to flash the BIOS from hard disk or a USB memory key. If you end up with a floppy, the usual procedure is to boot the system with the floppy and proceed from there. If there is an option to save the old BIOS, I'd do that, since BIOS flashes don't always suceed. Sometimes the old BIOS can be saved on the system, in the NVRAM I expect, sometimes you have to do it another way (like on another floppy, maybe). Anyway, this may help your problem. -Roger
