[SOLVED] Fans sometimes turn off and power indicator lights dim, PC runs slow

[peterng]

Hello All,

Hope all is well, not sure if this is the right sub to post but please move if needed. I have a ABS Stalker X ALI012 with a few modifications:

• Chipset Intel Z97
• Intel Core-i7-4790K (4.0 GHz)
• 16 GB DDR3 2 TB HDD
• GTX 2060 (replaced the original Nvidia GTX 960)
• Additional 500G SSD
• Cougar SL 600 Power Supply

It's been working flawlessly for years and i could be able to play a lot of games out there at Ultra. What happens recently is that sometimes the fan on the processor stops working, and the power button light dims. When that happens, the whole machine slows down, i can feel it on the monitor while playing game or just browsing the website, it's jerky and laggy. At that time, the CPU temperature can spike up to 100F+.

I've tried a few things like switching the fan, plugging the CPU into different outlet where there is no other appliance but the problem still persists. I also tried to open it up and place a big fan right to it, the temperature went down but the problem was still. It's intermittent, sometimes the fans turn off, the CPU heats up and the whole PC slows down. Restarting the machine does not help, i need to leave it there for hours and it will be back to normal.

Not sure if that's the power supply issue since i don't have a spare one to try. Should I go buy a different one or is it another issue with my rig? Thank you.

This is my first thought.....especially with the light dimming.
You could check the voltages with HWInfo.

Thank you, im not sure which one should be suitable for my rig and can fit in? can you please give some recommendation.

Here is also my HWINFO, where can i check for voltage and make sure its correct? Thanks

It looks like the PSU you have is of standard size so I don't think fitting should be a problem.
As far as what to get....there are so many model PSUs...good and bad...but in general...any Corsair or Seasonic is a good quality PSU. I'm running two Corsair RMx models at the moment.

Here are two good links to help you decide.

Thank you again for the info. It was really helpful. Maybe one last dumb question, does my PC fall under midrange system (tierB) or highrange system (TierA)?

I'd call it a midrange system but that wouldn't stop me from getting a high end supply if I wanted one.

The thing is...with power supplies...a bad one can ruin all your other hardware.

This is why it isn't a good idea to skimp on a power supply.

And as far as HWInfo....you have to click on the motherboard tab (I think) to get to the voltages.

You want them within 5% of +12, +5 and + 3.3V at idle and under heavy load.

It's your motherboard dying.

Thank you for your input. So do you recommend to get a new mainboard? any advise on which mainboard only that can fit in my rig as im tight on the budget now, can spend around $200 or less.
