pc troubleshooting

Hello everyone,
I'm in over my head with my computer and would appreciate some help.

The computer seems to work fine in every regard apart from these random crashes. the crashes seem to happen at any given time, so not only when the computer is under significant stress. I even had them happen whilst I was in the Bios.

before a crash occurs, the screen usually distorts in one of three ways. These distortions seem to share a characteristic pattern of diagonal stripes or dots.
after these distorted flickerings, the computer either completely freezes or a distorted blue image comes up, followed by an automatic reboot.

I tried updating windows 10 as well as running a clean installation for my graphics drivers but I don't really know what to next.

these are the specs of my computer:
CPU: Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz, 3501MHz, 4 core
GPU: NVIDIA GeForce GTX 570
RAM: corsair 8gb
Motherboard: Asus P8H77-V
operating system: Windows 10

Any help whatsoever would be very much appreciated.

Kind regards,
Jaap

I'd replace the video card or the motherboard.

Looks pretty old.
Whens the last time you gave the innards a good cleaning with some compressed air and a small brush?
If no help test with the side panel off.

thank you for your replies,

I cleaned the insides and replaced the conductor paste of my cpu 4 weeks ago but maybe that's when I messed something up.
I tried monitoring with msi afterburner but the temperatures seem fine. also the problem only started a week ago.

Still I'll try to clean it again and check if anything seems out of order.


But am I right in concluding that it's most likely a motherboard related issue? and is there any way you know of in which I could check to be sure?

No way to tell

In reply to: crashes

You just start eliminating stuff.

Get the innards nice and clean.
Make sure the cpu hsf is attached proper.
Test with the side panel off.
Your bios may have a temp monitor section so you can use that to watch the temps.

progress

In reply to: No way to tell

thank you so much for all the help, I actually made some progress.

I cleaned everything thoroughly and this didnt seem to help.
then I tried using the video card in a different slot, also didn't help.
but then I removed the gpu altogether and the problem was solved entirely.
so pretty sure it's just a broken gpu right?

however a new problem arose, without the gpu the computer now functions but only with a very long delay.
for instance, if you type something it takes about 10 seconds for it to show up on the screen.

this is not normal right? or would the introduction of a new gpu solve this too?
note that it didnt have this problem when the old (faulty) gpu was in place.

Slow typing

In reply to: progress

Without the gpu.

Boot the machine and enter the bios.
Does the keyboard react at normal speed?

If so boot into safe mode.

Answer
The 570 is from 2010

In reply to: pc troubleshooting

And pulls 219 Watts peak so it's highly suspect as well as any power supply that drove it.

Yes it is suspect. Only way to test is to try another card and this card in another PC.

If you are to replace it, a nod to the 1050 or 1050 ti from Nvidia. Less electrical power but higher performance at a nice price.

Example: http://gpu.userbenchmark.com/Compare/Nvidia-GTX-570-vs-Nvidia-GTX-1050/3156vs3650

The 1050 Ti is of course even better but you may be looking for a good price.
