Cyclic restart until complete power failure?


The trouble happened — the laptop (Acer Aspire 5520) when enabled, operates as follows:

1. Includes LEDs for power, WiFi and HDD

2. Includes cooler

3. Judging by the sound, initialisere CD-ROM

4. Completely turns off after a second or transition to point 1.

Started behavior of a sudden when surfing online.

There is a small suspicion that the consequences of overheating.

The service gave, was diagnosed with "problems in the power supply circuit" and put up the price one and a half times higher than the cost of a new motherboard from eBay.

Who can help with diagnosis (by advice or deed — if from Peter)? If anyone have a donor laptop of the same model with poperezhivat spare parts for diagnostics — I a symbolic fee.

And what's up with the donor to rearrange? The problem seems to be in the motherboard.
Try to remove everything (disk, memory, CD-ROM), if the behaviour is the same with the donor to remove, nothing special.

Either you have to order a motherboard on eBay (if beech sentimental value), or change the whole computer.
With donor you can try to rearrange video and Prots, there is some suspicion of them, for a couple of times the temperature of the cores and the GPU got to 78+. - rebeca_Sta commented on October 8th 19 at 01:26
Disable everything that could be tried. No memory/disk/cederom/protsa/video behaves exactly the same. - rebeca_Sta commented on October 8th 19 at 01:29

1. Change the thermal paste, if you have not changed. The machine I think 4 years...
2. If not most likely blame NVIDIA GeForce 8600M GT they mess up a lot on different laptops, the result otpisyvaetsya overheating GPU, but for this Hairdryer in your hands and go!
But it is shamanism helps more than half a year, then again... - rebeca_Sta commented on October 8th 19 at 01:30
Change thermal paste and clean all regularly. Second — I will try. - rebeca_Sta commented on October 8th 19 at 01:33
Preferably places that do not want to impose a heat foil. - rebeca_Sta commented on October 8th 19 at 01:36

He never comes to loading axis. At all. - rebeca_Sta commented on October 8th 19 at 01:32
