Question Laptop games crash, 3 lights flash then shutdown instantly

[Angelmaker30]

i have a 6 year old pc specialist gaming laptop in good condition thats developed a fault. On games i've always been able t run perfectly on high setting, the games now crash (sometimes after a minute, sometimes after 20 or 30 minutes). 3 leds flash then it instantly shuts down.

Specs
Chassis & Display Vortex Series:17.3" AUO Matte Full HD LED Widescreen (1920x1080) (£79)
Processor (CPU) Intel® Core™i7 Quad Core Mobile Processor i7-3720QM (2.60GHz) 6MB
Memory (RAM) 16GB SAMSUNG 1333MHz SODIMM DDR3 MEMORY (4 x 4GB)
Graphics Card NVIDIA® GeForce® GTX 675M - 2.0GB DDR5 Video RAM - DirectX® 11
1st Storage Drive 120GB INTEL® 330 SERIES SSD, SATA 6 Gb/s (upto 500MB/sR | 450MB/sW)
2nd Storage Drive 500GB SERIAL ATA II 2.5" HARD DRIVE WITH 8MB CACHE (5,400rpm)
DVD/BLU-RAY Drive 8x SATA DVD±R/RW/Dual Layer (+ 24x CD-RW)

Ive cleaned fans etc. checked the ram and the slots. I think its either cpu or gpu thats causing it. The system idles a little hotter than i'd like but nothing drastic. Any advice gratefully received

Check your laptop manual to see these 3 lights meaning.

Also check your SSD to see it is full or not, because 120GB SSD is very small, it can be filled up quickly. Usually you need to let it has about 10% free space , you can fill up the regular HDD, but not for the SSD.

Also like you said your laptop maybe overheat that caused by either cpu or GPU. You can use the software to monitor the temp.

Or use "Reliability Monitor Tool" to see you can find something or not.
