Over heating valiant 671 dp

My system is overheating. i think the cpu fan is inoperable. i also noticed the power supply was extremely hot. i was wandering if the system overheating because of a bad fan can also cause the power supply to be overworked because of electric load change durng overheating? i would appreciate any insight. thanks.

The power supply and laptop are both hot because your fan isn't working. You'd know if it was working by the whirring sound it would be making. Send it in for service.

Computer keeps overheating


Your power supply has a theoretical Maximum output of 700 watts, but the problem is that the hotter it gets the lower that number becomes... It's obvious your power supply can't handle the power draw or the heat from the Graphics card when taxing it by playing games... Two things you should do:

1. Make sure you have more than just your power supply venting hot air out of your case... Adding a fan or 2 will help take some of the cooling stress off the power supply.

2. Buy a better power supply... Newegg.com is a place I get most of my PSU's. Read their ratings and compare specs. You will notice on that site that your particular model is not rated very high.

Hi

The 300W Power Supply Unit is still somewhat under-powered 550W is required so that the computer is powered by a PSU working under minimum load strain and well within its power output capacity. 300W is the original Specification, See here:

Sometimes, positioning the base unit directly on a carpet with a thick shaggy pile, or enclosing in it, during use in a poorly ventilated under desk cubby hole, next to a radiator, or in place receiving direct sunlight, polarised by glass in the nearby windows or some similar place can have a underestimated impact on the base unit's ability to cool itself when in use. Cooling is essential for the CPU, Motherboard Chipset, Graphics Card or onboard Graphics Chip, Hard Drive and RAM Memory. All need to be as cool as possible to work at optimum efficiency and the performance of each suffers drastically when exposed to over hot conditions, particularly the CPU which, from stone cold, can reach the temperature of boiling water within seconds of the computer being powered up and will underperform, overheat and shut down at the merest incidence of over hot conditions. So review all the salient cooling issues, then consider adding a separate, dedicated, fan cooled graphics card, its GPU Fan adding to the efficient cross circulation of cooling air to more of the interior and, also, its own built-in GRAM freeing up the 16Mb, 32Mb, 128Mb or 256Mb of System RAM that the on-board graphics chip borrowed from the RAM Modules. RAM that has to work less hard, works at a cooler temperature and thus more efficiently. The CPU works more efficiently as it no longer has to compensate as much for the loss of System RAM previously commandeered by the on board graphics, so it also generates less heat in doing so. Consider removing the (usually) green coloured, plastic Heat Conduit over the CPU and changing the CPU Heat Sink for a more effective, higher quality one, the leaving the conduit to one side. Cooling is about the rapid movement of vast volumes of air. The conduit works against itself by unnecessarily confining the hottest component in the case - the CPU. See an example here:

Consider also Inexpensive but beneficial, cooling Motherboard Chip and RAM Heat Sinks for the RAM Modules. Inexpensive, underside fan powered Hard Drive Coolers that screw to the underside of Hard Drives. See examples here:

http://www.amazon.com/Thermaltake-TMG-HD1-HDD-Cooler/dp/B000ZM8D4I/ref=sr_1_1?s=electronics&ie=UTF8&qid=1315115079&sr=1-1

The 550W PSU is necessitated by the extra cooling devices you contemplate installing

My motherboard keeps on overheating @ 70C and over plz what must i do?


Hello and Welcome to FixYa!

If the overheating is not due to hardware issue, faulty components, you can control the temperature by using Heat sinks and Temperature controlling fans, and by regulating a proper Air flow to the unit. For this, you can also use Cooler Master casing specially designed for high end purposes, or can use any such available brand to control the temperature...

I turn the laptop on but it immediately turns off within seconds


1. First step is to check if the laptop is overheating:
  • Does the bottom feel very hot to the touch
  • Is the CPU fan not spinning up
If it is hot to the touch and the CPU fan is not spinning up, this will cause the system to overheat and shutdown as a safety feature. In this case the fan would either need to be cleaned or replaced.
2. Failing hardware can also cause this (i.e. a failing motherboard, CPU, Battery, Power Cable, internal PSU, etc.):
  • Did you notice any system freezes or slow down prior to this happening
  • Have you noticed a sharp decline in battery life
Try disconnecting the battery and then only use the power supply cable to power up your laptop. If the problem still occurs, then reinsert the battery and remove the power cable and attempt to start up the laptop with only the battery inserted.
3. In some cases this can be caused by a malware (virus) infection. The infections that cause this can sometimes be remedied, but usually require expert assistance and the remediation process is very specific to that type of infection.
  • Does it get to the first splash screen (i.e. the BIOS splash screen)
If it doesn't get past (or even to) the BIOS splash screen (usually a Dell Logo) then that would point towards it being a over heating issue or Power issue.
Having said that, it's more likely a hardware issue (i.e. dead to dying Battery, failing Power cable, broken CPU fan, etc.) instead of a virus infection. Make sure to check the first two steps to get you closer to properly troubleshooting your issue.

My gateway computer do not turn on.the fan try to start and stop.what should be happenning?


I think that the CPU fan isn't working as it should and the CPU is overheating quickly. If the CPU is heating too fast, the mainboard is automaticly shutting down the all PC to prevent damage. Your thermal paste might be gone. Isn't the computer giving any sounds or LED flashes ?

Is my cpu getting to hot my cpu fan runs in high speed a lot. do i need a bigger fan or my cpu is going bad.


Neither.

Turn the computer off.
If it is a HP laptop, remove the battery.
Disconnect the AC power.

Buy a can of compressed air, and give your computer a "blow-job",
to blow all the dust away from the heat-sink on top of the CPU,
and also, if it is a desktop, from inside the power-supply.

A layer of dust is a layer of insulation, preventing the heat-sink on top of the CPU from "radiating" the heat away from the CPU. So, your motherboard is detecting that your CPU is "too hot", and automatically speeds-up the cooling fan, to try to move the heat.

Turns off


I assume you have a desktop computer. It is either the CPU is overheating or the 'Power Supply" is overheating/failing. Put your hand at the top back of your computer where the power supply is to feel if the fan is blowing air out the back. If there is no air coming out the back, then I think the fan has failed and the power supply overheats and fails. Repair or replace the fan before the power supply totally fails and has to be replaced.

Also check the fan and heat sink on the CPU. If they are loaded down with dust, the CPU is not getting cool enough, With power OFF, remove the fan and heat sink, clen them and put them back. That will do wonders to cool the CPU.

I've had a bad dust problem and my cpu fan began making a loud whirring noise and finally the computer shut down altogether. Took the cover off totally cleaned out the dust and turned the power back on....


If the computer detects overheating or fan failure it will shut down automatically. If you replace the fan you should be fine. Remove your old fan and try to get one that connects the same way, some of them connect directly to the heat sink, others to the motherboard.
