My computer shut off for no apparent reason, what could be wrong?

Question

It shuts off for no reason about every 10-11 days. I have to turn it off in the back then turn it on for it to work again. What could be the problem. It's a LG and I had it almost 18 months.

Answer 1

Does it turn off or fail to work? If it turns off by itself, it is most likley a power supply problem. You need to look on the power supply to find out the watts it puts out. Then go to Best Buy or another Computer outlet and get another power supply. It should cost you no more than $50-60 bucks. You don't need a Computer Tech to change it out for you. If you feel confident enough. Remember what power connectors go to what, unscrew, change out and replug.

If your computer stops working but you can still see the screen you may have a memory problem. Either you need more or you may need to clean your memory pins which are located on the memory sticks (thier gold colored).

I am shying away from the thought of it being a heat problem, because I think if you had a bad CPU FAN or power supply fan, then it would overheat faster than 10-11 days. I agree with the above that you should examine the components inside for any damaged capacitors and such. Look for dark brown spot on the solder points. Aside from that, check for viruses. If you can not determine any problems, consider doing a system restore back to before this started happening.

Well, my first instinct would be that it could be the Power Supply. There are really a number of things that could cause the problem. Especially when you say that you have to turn it off at the back of the unit before you are able to power it up again. Power Supplies, depending on age, come with a thermal protection device (among others) that will shut itself off if it reaches a critical temp. Some even require to remove the AC power cord before it will reset because it latches in the "off" position. They are relatively easy to replace and I would try that first. Hope this helps....

likelihood is, it is your means provide going undesirable. As they age, they could't positioned out as a lot means. Leaving them operating 24 hours an afternoon hurries up the growing older procedure. attempt this regularly happening, inspite of the actuality that: top-click on My pc, and choose homes from the drop-down field. Then, click on the stepped forward tab (on the accurate), and close to the bottom, less than Startup and restoration, click the Settings button. as quickly because it opens, uncheck immediately restart. once you're having a difficulty that is regarding at least something else, like a stick of RAM going undesirable, it grant you with a blue demonstrate of death, fairly of restarting. If that doesn't ensue, you'll recognize that is the means provide.
