Is my CPU bottlenecking my GPU?

[tgimike]

When i first purchased the MSI R7 250x an error would always appear telling me that my "display driver has stopped working". However this is not the first GPU for this to happen to. All other previous GPU's i've purchased have had this same error. I've fixed the issue by going into MSI Afterburner and lowering the Core Clock and Memory Clock. I've googled around and the only solution i've encountered is that my CPU is potentially bottlenecking my GPU. The CPU I use is the AMD A6-3620 APU with Radeon HD Graphics. I just really want to know if I do upgrade my CPU would the problem be fixed. Thanks!

Full PC Specs:
CPU: AMD A6-3620 APU with Radeon HD Graphics
GPU: MSI R7 250X 1GD5 1GB 128-Bit GDDR5
Motherboard: MSI A55M-P33 FM1 AMD A55 (Hudson D2) Micro ATX AMD Motherboard
Memory: 8GB DDR3
HDD: Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache* (pretty sure lol)
PSU: RAIDMAX RX-535AP 535W ATX (80 PLUS BRONZE CERTIFIED)
Operating System: Windows 7 Home Premium (64-bit)

I dont think that CPU will bottleneck for a significant margin the GPU you have. If anything, the PSU is the one that might bottleneck your system. That brand of PSU only have tier 4 and 5 PSU. So you should change it, even it its not the source of your troubles.

It might also be a software problem:

You can start by uninstalling the GPU driver(run the driver installer and select uninstall). If you used an nvidia card before your should try to run this uninstaller: http://www.guru3d.com/files-details/display-driver-uninstaller-download.html. And then install GPU drivers agains.

If problem persists you can try to do this: https://support.microsoft.com/en-us/kb/929833

I tried both solutions. I wiped the GPU drivers and reinstalled them. Nothing. So i tried the other solution with the System File Checker, I DID have many corrupted files, but nothing to resolve my problem. I don't think it could be the PSU since the total wattage of my pc is quite lower that my current PSU. I have another PSU, but it's lower wattage and when i installed it, the same problem occurred. Thank you for the reply though.

If by lowering the speed of your GPU you fix the problem, its probably a PSU problem, because when you do that your GPU will require less power to work.

The PSU you have is supposed to give 430w on 12v rail, but it might not git it, since its not from a good brand and specially if you have it for more than 2 years. And your system ca pull more than 300w at 90% load.

You can also check this thread, it might help you locate the source of the problem:

But I dont think its a CPU problem.
