Question RX 6600XT + i5-11600KF black screen

[sirbetr]

Hello everyone, I had i3-10100F and MSI H410M-A Pro, I bought i5 11600KF and H470M-K. Now my problem is black screens, sometimes when I do alt + tab in game my screen goes black and I had to restart my computer. I checked my ram with windows ram test and memtest86, I did CPU stress test and benchmarks there is no problem. I thought my new mainboard is a problem then I changed my old one, I didnt get any crash or black screen. Its happening for 3 days in CS2 and today I tried my new system OCCT Power test for 30 min nothings happened, I tried FurMark for 10 mins nothings happened again but I did a benchmark in GTA V when I alt + tab its happened again. Please help me I am gonna mad its happening for 3 days. My RAMs 2400 and 3000 mhz but its showing basic mhz 2133mhz is it a problem?


My old specs: GPU: XFX RX 6600XT, CPU: i3-10100-F, RAM: 8x2 Corsair 3000mhz , G-Skill 2400 mhz, Mainboard: MSI H410M-A PRO


My new spec: GPU: XFX RX 6600XT, CPU: i5-11600KF, RAM: 8x2 Corsair 3000mhz , G-Skill 2400 mhz, Mainboard: Gigabyte H470M-K


Note: My BIOS updated, GPU was latest version but I thought the problem about the driver and I am now using 23.8.2, windows updated, I mean all drivers updated.

Yeah I bought today i5-11400f, but I didnt try the motherboard because my old motherboard not supporting 11th generation cpu, I will refund my motherboard. I am doing memtest86 rightnow its been 1 hours 20 min pass 3/4 no error. I would like to ask one more thing, if my motherboard is broken why I dont get black scrren with my old cpu 😖

should have gotten a cpu with igpu, then you could test with the igpu
