Starts up not all the way then shuts down thermal shutdown put in new power surply

#1 on the list for this is shut down from over heat due to CPU fan not running or CPU overheat. Check to see if your CPU fan is turning on when your system is powering up. If its not.. thats your problem (get a new fan)... Even if it is it could mean the fan is not properly contacting the CPU with thermal paste. If this is the first time you\'ve powered the system up, your next step is to go out and get some thermal paste and put it under the CPU fan, if you\'ve been running the system and this problem just cropped up.. skip the thermal paste, its already there. #2 Next possibility is BIOs power settings are incompatible with your hardware. For example the frequency on the CPU is set higher then it can operate and its over heating. Some systems will automatically shut down and restart with default settings others you have to get into and set to default. can you get into BIOS? Can you reset your BIOS settings to defaults? Check your mother board manual. #3 A compenent is shorting out your system and needs to be replaced. Is the system posting prior to shutdown (beeping once on start up?) If its beeping more then once that means something else and you should read your manual. If its not beeping then its a short somewhere and you can bet you have a bad part in the system. To identify which part it is you can either disconnect things (RAM, Drives, vid card, PCI cards,ect) one at a time, attempting to start the system after each one or you can take everything but the bare bones out and try to start it. I usually take all the RAM out but one stick and start by testing them. Your RAM is the most likely place for a problem in this situation. #4 If you\'ve striped it down and it still can\'t get a boot (with no post beep). You need to replace the mother board.

I installed a new alternater th battery is new

You also should change the thermal paste. If you want to play games, please choose normal PC. I think you are asking too much from your laptop.

Most of the reasons for automatically shutdown are lack of cleaning or cooling. Clean your computer and put one (1) drop of thermal paste on the cpu core. Also your system files are corrupted or infected by viruses.

Please rate me

take the power surply out and under it should be a black valve on a small hose take it out and push the pin in, if it is in already then ther is no presure in the line, put it back together leaving the valve out, then start the compressor up and see what the valve is doing, it should be out again and it will not release untill u push it in.so if it comes out then you are closer to the solution, also ther should be a little round plasic connector that the valve hits when the switch is turned off or auto shut off, make sure that is there on the power surply and not built up of **** then just put it back together.hope this helps

There are several reasons for a pc to shut down. One of the main reasons is overheating.

Did you properly put on thermal paste on the processor?

Ddi you check your processor fan to make sure its working and working fast enough to cool the proscessor?

Check all these things and if they are not done, put more thermal paste on processor and get a new fan.

If that does not work, the board may be defective and needs to be replaced.

Hope this helps

Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the computer back on and figures out a way to foil the protection, the unit is probably doomed. Once a unit shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated unit is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning. Check the CPU fan if it is spinning and also the CPU itself put thermal paste. So that the heat from CPU will absorbed by the heat sink.

Hi there... It may require some settings change in Power options of your NB.. Follow these steps, these may help...
Option 1:
Go to Control Panel - Power options - Double click - under Power Schemes, make sure 'Turn Off Hard disks should be selected as 'Never", System Standby "Never" Adjust Turn Off monitor accordingly..
Go to the next tab 'Advanced' and select the option accordingly..

Option 2:
-This may be the problem with the RAM on your NB, take help from Hard ware tech and reseat the RAM card

Option 3;
If nothing works, may a prb with the OS on the comp, may have to reinstall the OS ..** NOte: Do take a backup of all the important info on your computer before Reinstalling / Repairing the OS...

All the best...

Your CPU is likely overheating. Very likely the thermal conducting material between the CPU chip and the heatsink may have shrunk and now impeades the thermal transfer.
You may need to remove the heatsink and put new thermal paste and perhaps copper shim to restore the thermal contact to the heatsink.

You must have the CPU fan plugged into the CPU fan power connector or the system can not monitor the fans speed. Your PC will shut down & give you that message. (The fan must be connected to the correct power plug).
If when you did replace the CPU's fan & had to remove the heat sink, which is where the fan screws into & did not clean the old thermal grease off the CPU & heatsink & replace with new thermal grease than your CPU will still overheat. If you add thermal grease over top of old thermal grease your CPU will over heat.
This is all a balancing act. If any one is not correct your system will shut down. (This is better than killing the CPU).
To remove old thermal grease use a clean cloth damped with house hold alcohol & use the same on the bottom of the heatsink. Please allow plenty of time for the alcohol to dry.

Good Luck! Take your time.
