My computer recently started getting a blank screen before it can get past the login screen. The computer will boot up, get to the login screen, sit for about 5 seconds, and then the screen will go blank. It doesn't make any weird noises when it happens. The thermometer for the CPU on the motherboard goes blank as well when the screen goes blank, but the temperature is never anything crazy right before it gets a blank screen, under 30c, and the fans keep running on the case, CPU and the graphics card, the lights on the MOBO also stay on, just not the CPU thermometer. I have thoroughly cleaned the entire computer, pulled out the graphics card and cleaned that, reapplied new thermal paste, made sure all connections are secure, reset the CMOS, and I have no idea how to proceed at this point on figuring out what is wrong. I did have a problem a few months ago with the CPU overheating, but after I cleaned everything and reapplied thermal paste, it worked great. There was another issue where I would turn on the computer, and fans would run, but nothing would happen until I hit reset and then it worked normal. I could never figure out what was wrong and just hit reset if it did not turn on correctly. I built this computer 4 years ago with

Case: Corsair Carbide Series 300R Black Windowed ATX Mid Tower Case
MOBO: BIOSTAR TA990FXE AM3+ AMD 990FX + SB950 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS
CPU:AMD FX-8350 Black Edition Vishera 8-Core 4.0 GHz (4.2 GHz Turbo) Socket AM3+ 125W FD8350FRHKBOX Desktop Processor
GPU: XFX Double D Radeon HD 7870 GHz Edition DirectX 11 FX-787A-CDFC 2GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
RAM: G.SKILL Ripjaws X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C10Q-32GXL
PSU: Thermaltake Black Widow W0319RU 850W ATX 12V v2.3, EPS 12V v2.91 CrossFire Certified 80 PLUS BRONZE Certified Modular Active PFC Power Supply
HD: Seagate Desktop HDD ST500DM002 500GB 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive
CD: LG Electronics 14x SATA Blu-ray Internal Rewriter without Software, Black Model WH14NS40 - OEM

and upgraded to a 1 TB Seagate SSHD later on when I purchased Windows 10, I still have the old hard drive hooked up. I have attempted to read any articles on here related to this type of issue but if I missed something I apologized just point me in the right direction! Thank you in advance for any help

UPDATE: I went and bought a new cheap video card and the exact same problem happened. Waiting for a cheap mother board to come in the mail so I can switch that out and see if that is the problem. After that I am going to try the power supply. Still taking suggestions on things I can try to fix this! Thank you!

No, the kit is a dual channel kit because it has two modules, and the motherboard is capable of dual channel as well, but you can still run single channel with one stick. RAM is easy to troubleshoot because you always gets at least 2, so testing and troubleshooting is easier than other hardware.

Test one stick at a time, that will give you an idea of whether it is a problem with RAM, BIOS, or something else. You don't want to update BIOS with an unstable system, so testing RAM is usually the first thing to do since you have 2 to test with.

I did not check to make sure I have the latest BIOS, nor did I try testing the memory modules. The RAM is dual channel so I would need to test 2 at a time correct? I am getting a PSU tomorrow and I am going to switch that out to see if that is the issue, found some other posts where that was the problem and the symptoms sounded very similar. If the PSU switch does not fix the problem I will try the BIOS first, althought I dont know if it will stay on long enough to update anything, and then the RAM. Thanks for the help and I will keep this updated!
