Question

PC shutting down and rebooting by itself twice everyday,

Hello,

Today I turned on my computer in the morning, then I went to play a game and maybe 10-15 mins while in the game the computer turned itself off. Try to turn it on and wouldn't turn on. Then 1 minute after turned on again.

Then maybe almost 1.5-2 hours after finishing my game the computer turned itself off again but this time I didn't try to turn it back on since I decided maybe needed some cleaning, checking cables, etc. While I was waiting maybe 3 mins after the computer turned ON by itself!

What could be the problem? I haven't installed anything and temperature readings seems fine.

Any suggestions? I went to event viewer and this is what I found:

Thanks a lot for all your help. I really appreciate it.

Clarification Request
UPDATE

In reply to: PC shutting down and rebooting by itself twice everyday,

This issue is very strange. The last 2 days the computer was running perfectly, I even thought the problem fixed by itself. Then today has already shutdown 5 times!!! the times it didn't shut down yesterday and before yesterday is doing it today..

Please help.

That dump was not needed.

In reply to: PC shutting down and rebooting by itself twice everyday,

Your first paragraph points to heat issues. So without any PC make/model/age or such I'd get its maker to fix this overheating issue. The overheat can cause hardware damage but...

Many PCs have a setting in the BIOS to resume after power loss. For now, turn that off.

Heat is not the issue

In reply to: That dump was not needed.

That's not possible because this only happens first thing in the morning twice and the rest of the day working perfectly so heat is not the issue.

Here are my system specs:

Processor: AMD FD6300WMHKBOX FX-6300 6-Core Processor Black Edition

Cooler: Cooler Master Hyper 212 EVO

Motherboard: ASUS M5A97 R2.0 AM3+ AMD 970

Hard Drive: WD Blue 1TB Desktop 3.5 Inch SATA 6Gb/s 7200rpm Internal Hard Drive

Video Card: Sapphire Radeon HD 7790 OC 1GB DDR5

Power Suppy: Cooler Master eXtreme Power Plus 500w

The story is classic.

In reply to: Heat is not the issue

Then it's got to be another hardware issue like the motherboard. These look like new parts so start RMA on the part you suspect.

The 500Watt looks slim. With it's split rail design, +12V1@18A, +12V2@18A, you would have to be an expert to not overload a rail.

How could I check which part could be causing the problem. I bought everything brand new in October 2013.

Do you think the power supply is very underpowered? but strange that this never happened to me before.

That's a great clue.

In reply to: R.Proffitt

PSUs lose capacity as they age. So if it was OK new and it didn't have a lot of spare power over time it could cause trouble.

If there is a problem in the industry it's the lack of BIT (built in test.) Today we rely on experience, symptoms and swapping parts. This doesn't sit well with folk new to PC repair.

One of the things that derails your post is the dump in the first post. It means folk have to scroll through all that to comment and if it was some software issue, you could reload and move on.

I appreciate all your help

In reply to: That's a great clue.

Update:

This is strange. After 8 reboots aprox today I decided to reboot one more time and has been working perfectly ever since. What do you think is going on? does this add a clue to the problem or the PSU can still be the problem?

So according to this this PSU like to work warm not cold, I don't know, I'm just guessing.

Here's a screenshot of OCCT values:

After running the stress tests the values stay the same.

The thing about eletrolytic capacitors is

In reply to: I appreciate all your help

They perform better after a warmup. You can google BAD CAPS to see that symptom but I'll not be vetting this old issue. Your graphic is too tiny. A simple link to the image may have been more usable.

So let's say it's working fine. Wait another day after it's been off. If the caps are in play such as an aging PSU or BAD CAPS on some board, then the issue will return.

I apologize, here's a direct link to the image:

If this is the case should I leave my computer ON all the time until I get a new PSU so I don't have to deal with these "cold reboots"? it's basically ON all day since 6:00am until 1:00-2am.

all things are possible

In reply to: Heat is not the issue

still sounds like heat causing something to cut out, then when it cools down the trip meter resets itself and if you have "resume power" following a power loss on in the BIOS, the computer restarts.

Answer
Memory Card

In reply to: PC shutting down and rebooting by itself twice everyday,

Have you checked the memory card or memory bank? It happened to me two days ago, and my roommate found the memory bank loose and plug in again, my computer was back to work.
