Hello,
My computer suddenly started shutting off, then, after a second or two, restarting -- as if I turned it off and on. There are no error messages in the log files. In the BIOS, I set it not to restart, but it does. The only thing that shows up in BIOS error logs is Keyboard not connected -- but I have a Saitek that I connected months ago. (Long enough for the darn key caps to start wearing off.) The keyboard shows up in the device manager.
I have an 80 gbyt HD
CD/DVD/RW drive
Floppy drive
Logitech wireless mouse (marble mouse)
Board: Intel Corporation D915GAG AAC64123-302
Serial Number: BQAG43717011
Bus Clock: 200 megahertz
BIOS: Intel Corp. EV91510A.86A.0431.2005.0324.1533 03/24/2005
3.40 gigahertz Intel Pentium 4
16 kilobyte primary memory cache
1024 kilobyte secondary memory cache
Windows XP Home Edition Service Pack 3 (build 2600)
The problem became evident when I tried to upgrade Webroot Spyware -- and the update just took off and hogged 97% of my system resources, forcing me to shut it down and remove it.
I've cleaned everything in the tower.
Removed and replaced the conductivity jell on the heat sink for the chip.
Removed the side of the tower and added a desk fan to blow into it.
BIOS reports temps running around 158 to 160 degrees.
All fans are functional.
Have run Spybot S&D to check for problems.
Have cleaned the registry with 3 different registry cleaners.
Used advanced Windows Care V2 to repair problems.
I use AOL landline, not DSL or Cable, as an ISP.
System shuts down and restarts at short intervals when I first turn it on in the morning. The intervals later grow longer, ranging between 30 minutes and 8 hours. Sometimes, even that interval shortens.
PLEEEZE don't tell me it's my motherboard!
BTW, system is 4 years old. Built specifically with a huge power supply at a reputable computer store. It's not off the shelf.
Any help will be much appreciated and please note, I'm not exactly real computer smart.
Thanks
