Sudden Computer Re-Start

by billvonr / December 16, 2012 11:58 AM PST

I'm running an HP desktop (Pavilion Slimline s7600n) with Windows XP, used mainly for e-mail, internet, and MS Office applications. Lately, the unit is shutting down unexpectedly -- the screen 'Going to Sleep' appears, then immediately goes into restart mode. Very annoying, not to say unexpected loss of documents in process, etc.

I would welcome any and all suggestions on this problem and how to diagnose the issue.

How long since you cleaned it?

I'm pretty thorough on maintenance. Physically, I keep PC equipment clean and wiped down. Very liberal with the compressed air to get the dust out, including opening the tower and giving it a good blast. Software and OS wise, it gets daily care, deleting browsing history and temporary files. A more thorough cleaning of extraneous files weekly with Easy Cleaner, and at least once-a-month full system scan with Norton. Systems and software updates are all current.

Since this is a slimline unit it is a little more difficult to deal with but just from what you have said and since you have basically followed standard procedures, as per Mr. Proffitts link..hmmm. I am thinking heat, lack of cooling might be creating your shutdowns. On a regular tower we'd pull a side panel and see if perhaps the CPU or a cooling fan was not doing it's job well enough, creating enough heat to create a shut down. And of course it could be the PSU starting to drop out, similar effects to yours can/could be created by a whimpy PSU.

The basics done, now for your 100,000 mile service.

There is a bit of work we do on older machines that usually is never done since folk replace the cranky machine since a service counter will be around 100 or more to do this. If we DIY it's a few dollars. What is it? Replace HEAT SINK COMPOUND on CPU and possibly the GPU.

Some owners will trot out temperature readings so you nod and hand the machine back if they insist that's not it. But it's something I've done too many times.

Yes, it could be an old power supply but the owner or PC has given us clues to the non-operational fan by them.

There are some older machines that you just hand back. One of the ones on this list is at the top of the list is any Socket A machine. These are not accepted for repair since owners may think you can fix that model. That one is well beyond its service life and owners that want them fixed have to go elsewhere. No reason for the shop to get a bad rep over a machine that was repaired and still is cranky.

Finding the best 360 camera

GoPro, Pixpro, or Ricoh?

You can spend hundreds or even thousands of dollars on a 360-degree camera. We tested three of them to find out what kind of quality and ease of use you can expect at each price point.
