computers turns off randomly, but power supply stays on

by duncanrd19 / April 5, 2005 1:11 AM PDT

The computer is a Hp 503w. It has a celeron 1.7 processor, 128mb of ram, and is running xp home. It stays on for random amounts of time and then shuts down with no warnings or errors. It can be in an application or doing nithing at all. When this happens everything is off, but the power supply fan is still running. You have to hold down the power button for a few seconds to get it to go off before you can boot back up. When it boots back up it gives no error messages. Antivirus is up to date and has found no viruses. The system temp runs between 35 and 38 degrees celsius. I have replaced the power supply and ran a system recovery on the hard drive. It still has the same problem. Any suggestions out there?

Try these...

Review your "power management" setting and verify they are OK. You can ply with it, but I suggest "turn-OFF" any hiberate or slep modes for all devices and see if that helps. Also, under the bios area, check the system setting for "over-temp" control. Verify what it is and what action it takes, it may reach a certain temp and shutdown as it safety measure. Also, run an AV and malware scans fro any possible infection/attack. It maybe possible your HP model could be problematic so check the HP support website for any FAQ or known problems plus thier forum and query there. Check the p/s wiring at the mtrbd. for any loose or apparanet weak connection.

Duncan, More Things To Try
by Grif Thomas Forum moderator / April 5, 2005 3:02 AM PDT

128 MB is a bare minimum for XP..Try getting at least another 128 MB. While adding the extra RAM, make sure that your current RAM is seated correctly and working.

Although this sounds like a hardware issue, please try all the procedures below to make sure the computer is clean and running with fewer program conflicts which could cause freezes and shutdowns.

First, download, install, update, then run ALL of the free spyware removal tools from the links below. Delete all spyware found:
