facing PC issues that makes no sense

[ochin]

I know its like an essay but please help me out

my pc config is

i3 2100- 2nd gen
msi-h61m-e33
4gb corsair vengeance
Sapphire 2gb 7850 gpu
550W thermaltake smart PSU

bought the pc back in 2012 only played multiplayer games like bf4,cod4,lol

recently after a gaming session i left and when i came back there was a burning smell and the pc wouldnt boot it was stuck in a ON/OFF cycle. after a few hours the pc did boot but there were some problems im listing those down.

1) After booting the pc runs fine till i start a game like league of legends whenever the game starts the pc restarts

2)if i open the gpu and then play the game runs just fine, but after turning off the computer and turning it back on after a while the ON/OFF cycle starts and the pc boots only after a few cycles


3) yesterday i took the pc to ryans for them to find out whats wrong(i have tried everything to find out whats wrong) but the pc ran OK even with the GPU!!!!

4) after coming back i started a match in league of legends the graphics quality was set in low and the game ran just fine and IN GAME i maxed all the graphics settings and it ran perfectly until i finished the game and joined another. the funny thing is the pc restarts ONLY if i start the game in high settings but runs ONLY in low settings and this is a very peculiar problem.

5) with the gpu the ON/OFF cycle is still there and takes a few cycles to boot

many will say its a psu issue or gpu, i thought the same till i brought in a generic psu and started the pc without the gpu the On/off cycle was still there.

my guess is its a motherboard issue but im not sure that is the reason im posting this HUGE list of problems so you the experts can help me out .

Do you use ups? Check the power cable connected to the psu, reset mobo bios by jumper or battery. Check your mobo for burn marks.(opposite side as well)

Could be a partly damaged CPU VRM, Best way to check it would be to stress test the CPU.

Bios Reset : usually taking out the battery for couple minutes will be enough.

Stress test: Use prime 95(!) or intel burn test.

so far when i took out the ram the motherboard was giving out 3 beeps for the missing ram. bbut now the motherboard does not give out any beeps even when the ram is missing.

Something has burned which is quite obvious. Check wall socket/multiplug/Fuse in PC power cable plug/power cable/PSU power socket @ochin

i think the multiplug you use should be checked properly and may be its a power supply issue as in under load like in low settings problem didnt occur but in high settings the gpu tends to go for more pressure on psu and it shuts down, try to run everything on different psu
