My monitor showing only vertical and horizontal lines due to GPU.

[aravindu43]

My Specs:

Motherboard: GA78lmt-usb3
RAM: Hyper Fury 8GB RAM DDR3 1866Mhz
Processor: AMD FX 6300
OS: Windows 10
GPU: r7250 1GB DDR5

Today I changed my RAM (ADATA 4GB DDR3 1600 Mhz to Hyper Fury 8GB DDR3 1866Mhz). But when I turned on my computer, only horizontal and vertical lines are showing (screenshot added). I tried my old 4GB RAM and still same problem is occurring. Sometimes windows loading screen comes and then this problem comes and then eventually the system get restarted.

I tried to access BIOS and then too while changing the setting the problem comes and then get automatically restarts.

I tried resetting my taking out CMOS battery but the issue still persists. I tried to connect by using VGA cable as well as HDMI cable but the issue persists.

Also I tried using the same VGA cable to connect another computer, but didn't find any issue with the cable.

So please help me in fixing this issue.


UPDATE: I have found that my GPU is causing the problems. Is there any way I can confirm that it's faulty or not?

Thanks in advance.

1| You forgot to include the CPU cooler, case, PSU, HDD and the SKU/model number for your ram kits. Please include them.

2| Have you made sure your BIOS is up to date?

3| It's probable that your GPU is either being starved of power or that it's cooling fins are clogged with dust/debris rendering it to go past thermal throttling thus the artifacting. If your PSU is to blame or bad airflow will be revealed in the followup post from you.

4| To test out f your graphics card it really the culprit, you're going to need to borrow the card from a friend and try it out your system(AMD ofc) or try your card at your friends house.

Hi thanks for the reply.

1| I'm not using a cooler in my CPU.
PSU using is Corsair VS450
HDD is 465GB Seagate ST3500413AS ATA Device (SATA)
Currently I'm using a single RAM: Hyper Fury 8GB DDR3 1866Mhz. Currently it runs @1600 CL9-10-9 @1.5V

2| SInce I'm not an expert with BIOS settings, I didn't do any BIOS update

3| When I turn on my computer, GPU fan will start running and from outer it works well. My PSU is new and I'm sure it's not causing any problem as with out GPU my system is working as expected.

4| That I'll try

Thanks for the advice mate.
