Please help, PC keeps crashing

[MightyPickle]

Hi I have had my PC up and running with no hiccups for about a year now and just 2 days ago it started crashing, the first day it happened every hour or so, second day only twice, and today its only staying on for about 20 mins before crashing. It also somtimes crashes while booting up. All my temps are fine but I did notice on restart after a crash my dram led turns red then away, also an led right beside the power led turns red too (motherboard is a ASUS M5A97 R2.0 AM3+ ) but I couldn't find it in the owners manual..

Specs:
AMD 8350 with h100i
ASUS M5A97 R2.0 AM3+
16gb corsair vengeance 1600mhz
AMD 290 tri-x
Evga 1300w supernova v2 PSU
Win. 8.1

All help is greatly appreciated

Edit: another mystery led to the right of the 1st pcie slot turns red on restart (was covered by GPU)

Edit 2: Im now not able to get into windows at all, it crashes a few moments after the Asus logo disappears.

Greetings,

May You please do the following?

1. Run Memtest x86 from usb/cd/dvd - 2 wall runs
2. Run Crystal Disk Info, and post a screenshot here [or write whether there's some yellow/red markers]
3. Run OCCT Linpack/Prime 95 for at least 10 minutes
4. Run FurMark, or MSi Afterburner for at least 10 minutes

And tell us which of the tests failed.

@uplink-svk before I could try any of these my PC crashed and now it crashes right after the Asus logo when booting.

 

[uplink-svk]

That's bad. You can have either a power surge somewhere, or bad memory, or bad graphics card, or bad cpu, or bad motherboard, or bad psu. Please do try to run memtest, maybe we'll get lucky.

 

[MightyPickle]

Ok I'll keep at it, if I can't get it to boot what should I do?

 

[uplink-svk]

Remove everything from the computer, put out even motherboard. Put motherboard on a paper, discharge any static from Yourself, and connect power supply [main rail, cpu support rail], one ram module [pick a random one], and a processor. If this won't work, one of those three is dead. I go to bed now, I'll be back within 10-12 hrs. Take care!

 

[MightyPickle]

Thanks for all the help!

 

[uplink-svk]

You're welcome, just, did any of those work? Does Your pure motherboard, with ram and cpu hooked up on PSU run just fine?

 

[MightyPickle]

I'm pretty sure the problem is the ram, my friend is lending me a stick to try it out. And again really thanks for all the help!

 

[uplink-svk]

Let's hope it's only a ram. Keep us updated for the situation!

 

[MightyPickle]

Update: it turns out one of my ram sticks was faulty and causing the problem, yha ks for all the help. I am wondering if anything else is damaged and what are ways to check?

 

[MightyPickle]

Also I was able to run kombustor no prob for over 10 mins

 

[uplink-svk]

Nah, there's not a big chance that something else will be damaged, so You should be fine. But, if You wanna be sure, run that Crystal Disk Info, HD Tune Surface test, MSi Kombustor/Furmark [You did that already] and OCCT Linpack, for at least 10 mins, and You're golden.
