Open the PC box. Check the CPU heatsink/fan for dust clogs. After that is cleaned, put a little fan blowing onto the mobo. An over heating processor acts just like this. If the BIOS were changed try to scale back a little, first. Just see if the venting solves its prob. Wont cost you anything, and it wont hurt....

My lenovo g560 randomly shut down


Sounds like your taxing your system too hard. Perhaps you need to purchase a beefy-er CPU, graphics card, or cooling fan.

DeepFreeze is a softwre which help you when you shut down or turn off your computer the virus will not save


Hello,

I have used deep freeze software. It is primarily used when computers are shared, or personally can be used for protection of your computer from virus or other malware.

If you create a file and save it, it will be deleted by deep freeze upon the next reboot, unless you open the program and reboot to the thawed mode first. In thawed mode you can create files or other items that will not be deleted. You can boot thawed up to 10 times, then the next boot will be in freeze mode.

Good Luck

My fat 60 GB PS3 just stopped working. Blinking red light persists despite multiple resets. Please advise


The manual clearly states a blinking red light is an "over heat condition" and your system has shut down to prevent a failure. You need to find more airflow for your PS3. If your system is cooled down and you are still getting a blinking red light then you will need to replace the CPU board because it has melted from excess heat. Click on the link below to send in your PS3 for warranty repair:

2 light is lit on front of cpu


That's not a problem. One light(Green one) is for power and another (Red one) is for Hard Disk. Red one will blink continuously, if hard disk is being accessed.

My CPU freezes a random times or when i reset it, video will not come on, but the cpu comes on.. I have to power it down a couple of times. Does that sound like a video card going bad? Radeon 7000 graphics...


it could be your graphics card going, before purchasin a new 1, check that all your fans are working and that your cpu cooling fan or heatsink has not come loose. those type of problems cause the computer to shut down because of overheat. last but not least your hard drive can be going bad and its hitting bad sectors causing it to shut down or freeze.

Dell 5150c shuts down orange flashing light


As a temporary measure, taking the side panel off the dell 5150c stopped it from shutting down, so in my case it was clearly a heat problem, as suggested by previous the poster. The following instructions assume you're comfortable replacing computer hardware components - do at your own risk!

The solution is to buy an 'air duster' and some thermal compound for the CPU heat sink. If your CPU fan doesn't sound healthy (mine didn't), also buy a new one (ca. £20 on ebay: search for G9474 ).

Read the service manual: http://support.dell.com/support/edocs/systems/dim5150C/en/sm/index.htm for details on how to install / remove the fan and heat sink.

Clean out dust from the heat sink with air duster. Remove the fan, and clean or replace (recommended). Also clean the grill in front of the fan. Clean off old thermal compound from the CPU / heat sink and replace with a thin layer of fresh compound. Replace heat sink and side panel and you're done.

Blinking red lights on startup


4x red blinking light on this system means it's "CPU thermal shutdown" this is done when the cpu fan fails to cool the cpu and the computer shuts itself down to keep you from burning up the system.
This could be caused by dirt, hair, dust in the cpu fan or heatsinc or because the fan has failed.
you can blow some canned (dry) air through the fan and heatsinc undernieth it and try to clean it. most likely you will have to take it off to clean it thoroughly or replace the fan. It is about a 15-20 dollar fan and your local computer shot or neighborhood computer guru can replace it in 10 minutes, so dont let then keep your computer longer than a day.
If your computer savy, remove the case, inspect the fan while the computers ON to see if it sounds weird or is not coming on at all. it has usually two retaing clicps the can be difficult to remove with the power supply in the way. so be ready with a philips head screwdriver and a notebook to write down anything you dont want to forget to put back. If you decide to tackle it, post again here after you check the above mentioned things and ill get you a detailed breakdown of how to do it. It real is not too hard.
Regards..
