Solved I have no idea what my issue is, but my PC restarts itself, and now Benchmark has my performance dropping a lot.

CPU: Intel Core i7-4770
GPU: Nvidia GTX 1660-Ti
SSD: Crucial MX500 1TB
HDD: WD Blue 4TB (2015)
RAM: HyperX Fury DDR3 1600 C10 2x8GB
MBD: Dell XPS 8700

My PC started as a prebuilt Dell XPS 8700 in Late 2013/early 2014
Since then I'd upgraded the RAM and GPU in late 2016
Then, about 5 months ago I got a new GPU, PSU, RAM, and switched from HDD to SSD

After I switched to the SSD and New RAM, my pc started to shut off now and then, I thought it was a PSU issue so I got a new PSU (Corsair VS650). And I decided at the same time to get a new GPU.


Since quarantine I've been using my PC more often, and I feel the problem is getting worse.
I ran the Memtest86 tests, and there were no issues, I changed some power settings (processor Power Settings in adcanced power options) from max processor state from 100% down to 95%

but in the past 2-3 hours my PC has restarted itself twice.
What used to happen was the screens would go black, I could still hear the fans whirring, and the lights inside were fine. It did nothing no matter how long I left it, so I had to restart it myself.
But today, it's been restarting itself automatically.

I ran a benchmark around 5 days ago, which gave this result
UserBenchmarks: Game 72%, Desk 80%, Work 62%
CPU: Intel Core i7-4770 - 75.3%
GPU: Nvidia GTX 1660-Ti - 75%
SSD: Crucial MX500 1TB - 103.2%
HDD: WD Blue 4TB (2015) - 82%
RAM: HyperX Fury DDR3 1600 C10 2x8GB - 57.8%
MBD: Dell XPS 8700

And this one about an hour ago
UserBenchmarks: Game 69%, Desk 71%, Work 56%
CPU: Intel Core i7-4770 - 67.1%
GPU: Nvidia GTX 1660-Ti - 73.6%
SSD: Crucial MX500 1TB - 103.2%
HDD: WD Blue 4TB (2015) - 80.8%
RAM: HyperX Fury DDR3 1600 C10 2x8GB - 54.6%
MBD: Dell XPS 8700


and this one right as I'm posting this
UserBenchmarks: Game 68%, Desk 71%, Work 56%
CPU: Intel Core i7-4770 - 69.3%
GPU: Nvidia GTX 1660-Ti - 72.9%
SSD: Crucial MX500 1TB - 100.6%
HDD: WD Blue 4TB (2015) - 76.9%
RAM: HyperX Fury DDR3 1600 C10 2x8GB - 54.2%
MBD: Dell XPS 8700


I Have no idea what's going on, why would my PC's performance drop this much.

Please help me

Click to expand...
VS = Value Series that are not intended for use with anything more than an entry level desktop, you really should have a minimum of a Gold efficiency rated PSU for a build like yours that has a gaming quality video card, cheaper PSUs are made with lesser quality capacitors and wires, both get real hot when under any load and the PSU will often shut down to stop it from melting, the add on GPU being the most power hungry is usually the first thing to suffer as is your GPU hence the computer still running but you having a black screen.

Try physically removing the add on GPU from the MB and then testing the computer using the appropriate video port on the MB, if my theory is correct you should not get any restarts.

My "crashes" were seemingly random. Some happened while playing a game, some happened while I was just watching a youtube video. and they were kind of sporadic with anywhere from a few hours to a few days in between.
Whether or not the PSU is the cause of the issues, I should still get a better one with a gold rating correct?

When you say testing the computer, what do you mean? Like Benchmark tests?
I took the GPU out and ran Benchmark, giving this result

UserBenchmarks:
CPU: Intel Core i7-4770 - 69.3%
SSD: Crucial MX500 1TB - 104.8%
HDD: WD Blue 4TB (2015) - 81.1%
RAM: HyperX Fury DDR3 1600 C10 2x8GB - 51.8%
MBD: Dell XPS 8700

Okay, so I'm going to leave it running for a while and see what happens

I'm looking at new power supples, right now I'm looking at an EVGA SuperNova 850 fully modular, which seems like it should be fine, but I don't really know computer parts that well.

Unless urgent can you avoid adding multiple posts and give us a chance to reply to your last, it is rather distracting when having to stop mid way through typing a response.

Replacing anything is always a last resort and before making any purchase it is always advised that you get your system tested first.

When you replace the PSU depends on if we determine here whether or not it is the cause of the problems that you are having, if you intend keeping the computer long term a Gold efficiency rated PSU would be a sound investment.

By test I just mean use the computer as you normally would, no point in knowing that the computer crashes under load without also knowing if it crashes when idle, knowing if the computer shuts down when not under load is actually more of a clue that there is a problem tbh.

It's always crashed when I was using it, it's never crashed while Idle.
I do plan on keeping this PC long term.
I can close this thread for now, and if the issue persists, start a new one referencing this thread. and if It does not happen again, Should I just assume that I need a new PSU?

Also, I don't know how I would close this thread.

thanks.

The below are the types of normal use a computer goes through, use yours as you normally would albeit without the GPU fitted.

Browsing only = idle, Watching a youtube video = mid load. Gaming = under load

Download and run SUPERPOSITION free and see how the computer behaves.

Your thread can remain open while testing, we should know pretty soon what is going on.

Okay, so Under 1080p Medium

score: 635
FPS
Min: 4.12
Avg: 4.76
Max: 5.63

Should I attempt 1080p High, it says VRAM limit is reached, and that the benchmark can crash. Is that what I'm aiming to do?
 
#13
We are not interested in figures only seeing how the computer coped and being that it did ok it does look like having the GPU to power is too much for the PSU.

Another test you can try, Furmark no rush as I`m going offline now as I have an early start.
 
#14
I ran furmark.
It handled the Preset 720 and Preset 1080 fine, I ran the GPU stress test for about 4 hours with no issue, no idea how long I should have let it go.

I was unable to run the preset 1440 or 2160, it said it could not switch to fullscreen mode and to try another resolution.
 
#15
Just continue to use the computer for the rest of the day and if still no problem you can either post straight back and let us know or chance putting the GPU back in and running the same two tests, the latter is totally your decision but if me I would not run Furmark with the add on GPU fitted as going by the outcome of your testing done up to now the PSU looks to be the cause of your issue.
 
#20
So now you need to replace the GPU and just use the computer for general use, no benchmarking and no gaming, if you don`t get any problems, try running just SUPERPOSITION then post back with an update for us, we need to do one step at a time to see what triggers the issue.
