Alienware 17 R5 , 7 beeps of deaths but works??

Hi, I have this strange issue , started a week back where my Led would intermittently shutdown and then the unit will power off soon after. Then when I reboot, it will sound a 7 beep code and then continue till I manually power off. I did some research and 7 beep means a faulty CPU or motherboard "BUTT" it works from time to time. I can power this in the morning works and dies either instantly or would carry on for 8 to 12 hours before the problem occurs again. I have to point out, in December of 2016 my GPU 880M died and was shorting the motherboard . I removed the external GPU and the machine is been working on the built in intel GPU ever since.
I even did a ePSA pre-Boot system assessment test and it cleared all, that took a while to complete and didn't shutdown during any stress tests.

What I would like to know is , is this the CPU acting Up?, is it the motherboard ( some component heating up). Has anyone encountered this problem and were successful in solving it.

Specs:
Alienware 17 R1 purchased in 2014 July.
Core I7 4710MQ
16 GB Hynix 1600Mhz
1 TB Western Digital Blue
512 SSD Crucial MX100
880m gtx 8gb ( 2014-2016, shorting the board, placing it in the MXM slot laptop wont even start)

 

Buy another motherboard, yours is on its way out.

 

Thought so.

 

I do have a similar problem but mine does not really post, all time 7 beeps, even with a spare motherboard. I replaced it with a temporary cpu and now i have no more problem.

 

I am leaning towards the motherboard rather the CPU. I am running the ePSA pre-Boot system assesment test again right now and its stress testing the CPU and other components , and I am sure it will clear that but as soon as it boots to windows it shuts down either within a minute or last 3Hrs which it did before, then started again with shutting down and beeping 7 times. I am compelled to try the nonsensical Blanket fix see if that helps.

Completed all stress test booting to widows now.

 

Smone please correct the title from "R5" to "R1".

 

It's known as R5 in various continents.

NA it's R1 though

 

When I bought it, the listing on amazon said R5 also tired changing it but there is no option to change the title. Unless I have missed some setting.

 

Yeah, it's either called m17x r5 or AW 17 r1, not AW 17 r5, that's the 2018 model. Just a bit misleading though, not that important.

 

A bit, but clarified in the OP with a purchase date, there was no 8th gen anything in 2013-2014

 

Update:

Took it to a reputable hardware store that fixes these sort of problems and even they were not able to solve the issue.They concluded on testing the CPU with a different board, which they didn't have so, stuck with purchasing a refurbished board with a spare I5 Cpu off ebay. This could take a while so will update when things move along.

 

I have an extra board from getting mine repaired. Tested and working, A14 standard BIOS. If you are US48 and interested PM me

 

Thanks for the offer but I am considering purchasing a barebone Dell precision M4800 at the moment this seems like the logical choice. No I am not located in the US and have to import most items.
