Intermittent stripey screen "crash" with AMD R7 265

I have a 2 month old Chillblast overclocked Windows 8.1 PC with a Radeon R7 265 graphics card. It has had 2 stripey screen "crashes" in the past 4 days.

Both times I had a few windows open, but nothing graphics intensive. Both times I was editing an Excel document, although I suspect that is just coincidence?

I was editing and suddenly the screen went blank and stripey. If it's relevant, the first time the stripes were grey / white on both monitors. Today the stripes were blue / white on my main monitor (DVI connection), while my other monitor showed a plain black screen (HDMI connection). (see screenshots below)

No idea whether other computer functions were still working as with no display I had no choice other than to hold the power button down to power down, but the PC rebooted without problems both times.

The graphics driver is up to date according to the AMD autodetect utility.

The PC is still under warranty, but tech support are not available until Monday. In the meantime has anyone got any suggestions for what may be causing this? Or is it most likely a faulty graphics card?

My system was built by the guys at Chillblast.com with the following spec:

Intel Core i5 4690K Haswell Refresh Processor 3.50 GHz (Overclocked to up to 4.3GHz)
Akasa Nero 3 CPU Cooler
Arctic Silver 5 Thermal Paste
Asus B85M-G Basic Micro ATX Motherboard - Haswell CPU only
16GB Corsair/Crucial/Samsung PC3-12800 1600MHz DDR3 Memory (2 x 8GB sticks)
Chillblast AMD Radeon R7 265 2048MB Graphics Card
120GB Samsung 850 EVO Solid State Drive
Seagate 2000GB SSHD Hybrid Drive
24x SATA DVD /-RW Drive
Aerocool Premium Grade 500W PSU (80 )
Onboard High Definition Audio
Windows 8.1 64 bit with Windows Classic Shell
23" Asus VS239HV IPS Widescreen LED Monitor - connected via DVI cable

Plus I have a second monitor - 22" Samsung Syncmaster B2230 - connected via HDMI cable.

Thanks in advance for any suggestions.

I'm thinking bad graphics card. Probably best to return it since under warranty.

No other graphics card to try? Can you run off the integrated graphics to see if it works?

Thanks for the reply, Popeye. That's what I thought... :(

Hopefully it will be easy enough to disable the faulty graphics card and remove it. I don't do hardware!

I'm sure I can use the integrated graphics while I'm waiting for a replacement though.

Since it's overclocked it maybe because PCIex port is overclocked to more than standard speed of 100 MHz. Should be able to put it's value on manual and 100 MHz in BIOS.

Thanks for the suggestion CountMike. I'll give it a try...

The stripey screen has only happened twice, so maybe it is as simple as you suggest.

I hope it will do the trick because the replacement graphics card the vendor sent is a different model and the power cable won't reach as far as the power socket on the card :think: I really don't want to lose the computer for 2 weeks while they sort it out for me...
