Hi, i need some help finding out whats wrong with my PC. Its specs are; R9 270X 2GB GRAPHICS WINDOWS 7 HOME PREMIUM 64bit FX-8350 Eight Core 4.2GHz Processor - Asus M5A78L/M-USB3 Motherboard 550 corsair 80 bronze PSU . Its about a year old, never overclocked.

The problem is that my computer started to "blink" white lines across the screen. They get more frequent until the PC reboots with blue/white and black vertical lines down the screen. Eventually the pc could barely be on 40 minutes before this crash happens. Games like the Witcher 3 experience heavy graphical glitches and crashes with the video driver. Benchmark test heaven would crash before completion.

There is nothing in the event viewer to give me a clue on where to start.

All wires are secure and checked.

Windows memory test was passed 100% and windows self check passed as well.

The only solution i have found is to uninstall and then reinstall my graphics drivers. This fixes everything,(the system can run games/pass benchmark tests) but only lasts about 2 days, before the problem occurs again. Any help would be greatly appreciated. All i can think is that i need a new GPU.

Thanks for reading

The PSU is a Corsair VS550 PSU. Brand new, These glitches have occurred with both PSUs ive tried. I have monitored temperatures of the GPU. During a benchmark it never got above 70 degrees. It tends to stay around 65 degrees during the heaven benchmark. I haven't monitored the CPU temperatures, but these glitches usually happen after the units been on for 40 mins.
Thanks for your reply

I can't find where you said you have tried 2 PSUs....VS and CX series are known not to be good quality power supplies and your being only 550W might be a problem. Do you have the latest BIOS? When you check CPU temperatures, check the thermal margins with AMD Overdrive.

Sorry I forgot to mention that, I have the american megatrends 1801 12/11/2013 BIOs. Im unsure on updating them because this is my first rig. Would the BIOS cause this? ive had this for a year and nothing has gone wrong with it until now.
But again thank you for your help

BIOS versions can cause instability.........http://www.asus.com/uk/supportonly/M5A78L-MUSB3/HelpDesk_Download/

Select your OS version and then download the latest BIOS version. If you don't know how to update, I can tell you step by step or you can watch youtube tutorials.

I will try with a replacement GPU.
But since it crashed again, I looked through the event viewer and found out that since it first crashed, the event viewer is filled full of Service control Manager errors 7000,7001, 7026. Could this be related?
