Graphics Card
SAPPHIRE Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card (100314-3L )

- No overclocking

AMD Catalyst Driver Version, and Driver History
- 8.98-120611a-141402C-ATI and one previous version I cannot remember

Operating System
- Windows 7 Ultimate Service Pack 1

Issue Details
- Every time I cold boot my system I need to hit the reset button between 1-5 times before I get a 'clean' startup.

What I mean by this is that as I start the Machine I can see graphical issues in the opening BIOS text, just parts of the text missing. If I let the computer continue to boot I will see 3 veritical thick blue lines accross my screen and it will BSOD before getting to Windows.

I can reset my machine between 1-5 times and eventually I will get a boot where the BIOS text looks clean and it will get all the way into Windows and once I'm there I have no issues whatsoever - I can leave the machine running for several days and experience no problem until i need to cold boot again.

I had a similar problem with a HD7950, and am in the process of replacing it under warranty.

The same problems that you have started for me when I used more than one screen, are you using more than one monitor? How old is the card?

I would just try returning it and getting a replacement if you can.
