My rig keeps incessantly restarting at startup

[ntraturownrisk]

Hi All,

I have a PC with the following config:

Corsair GS 600 PSU
Intel i7-2600k
Zotac GTX 560 Ti
2x4 Corsair Vengeance (1333 MhZ)
2x2TB Seagate Barracuda 7200 RpM hard disks (Raid 0)
Gigabyte motherboard (Kinda forgot the exact model number. Will update as soon as I find out)

This rig was running on a 1KVA UPS till one year ago and I had absolutely no problems bar the occasional failure to startup; i.e, incessant restarting at startup. I used to get over this by unplugging one hard disk and then starting the machine. Then after it would start, I would switch it off and plug the second hard disk back in and it would start up well again. Overall, this incident happened like around 10-20 times in the past 4 years.

however, since the last year, my UPS hit the shed and I've had to manage this rig without one (a cardinal sin. I know.). And due to the frequent powercuts maybe, it has stopped starting up a couple of days ago. As soon as I start the system up, it keeps on losing power and restarting itself. I've tried the thing I used to do with the hard disks but that isn't working either. If it is of any help, the GPU used to crash regularly before this happened.

The PC was used frequently for gaming, 3D modelling, video rendering and other such demanding tasks and it used to absolutely steamroll all those tasks.

Is it a problem with my PSU? Should I replace it? I'm a bit out of my depth here. Can someone help please? Thanks.

Looks like a failing PSU. Can you try another PSU ? How old is you PSU ?

Remove extra hard disks. Reset overclocking if you have overclocked your i2600k. Remove Graphics card if you have onboard graphics. Try to start system then.

Do you use a surge protector ? I'd recommend to use it if you are not using UPS in the power chain.

Hi Faun,

Thanks for the suggestion. I'll try unplugging the GPU and trying to start it. The GPU is 4 years old and has run its period or guarantee / warranty.

In the case where I have to get a new PSU, which one should I get, considering that the GS series has been discontinued (last time I checked).
Also, I had some inhibitions about the 600W capacity of the GPU. Is/was that actually enough for the rig or is it a paucity / overkill for the config?

600W is alright. But do check the source of problem.

Check this list and select one from Tier 1 or Tier 2 category. No reason to go for Tier 4 or beyond.

PSU tier list 2.0 - Power Supplies - Components

Antec VP550P -4400.

or

Seasonic S12II 520w -4900.

Go with any PSU according to your budget. As for the GPU is concerned you can go with Asus/Zotac GTX960 2GB OC @ 15.5k

Hi [MENTION=320507]ntraturownrisk[/MENTION],

I agree with [MENTION=20614]Faun[/MENTION], there might be high chances of the PSU and MOBO issue; but there are also other possible reasons like high temperature of CPU, faulty RAM, faulty HDD and Culprit PSU causing the issue. I give you some basic troubleshooting steps. It may help you to solve the issue.

1) Remove the Overclocking, if exist.

2) Download DLG software to check the HDD. If possible, try different HDD with same MOBO.

3) Try different RAM or MOBO to make sure that the problem is with the RAM or with the MOBO.

4) Try different PSU to make sure that the problem is with power or with hardware.

In the meantime, do you have any kind of temperature monitoring program installed? If yes, then would you mind sharing with us the temperature for the components that you can monitor?

Hope it helps.

First things first. Check if the PSU is fine. Unplug the PSU, connect the green wire with any of the neighboring back(gound) wire, using a wire, or any metallic paper clip. With a load attached to the PSU (typically your 12mm cabinet fan), power on your PSU. If the PSU starts, and the load works, then PSU is fine. This is a quick test.

Also, if the PSU is fine, unplug all the components, including the RAM (mobo have only CPU attached), start the PC. You should get beep codes, signalling no RAM module, if your motherboard is fine. This way you can rule out your motherboard being damaged too.

Hi All,

Sorry for the long layoff. Nevertheless, I finally tested out all the suggestions and turned out, my PSU is fine. My mobo is the culprit. I got a friend's PSU and the rig would still not start. The RAM worked fine on my friend's system and so did the hard disks. So, I think the case is pretty much zeroed down to my board. In light of the same,

1. Would you recommend getting the board repaired or replaced? I've heard that boards once impaired generally tend to fail over and over.
2. In the case where I have to get my board replaced, could you please throw some suggestions of good LGA1155 boards? Thanks.
