I have an i7-3770 on an Intel DQ77MK. Other hardware (all new) are:
- memory Geil GOC316GB1333C9DC 8G+8G (officially tested by Intel for this motherboard)
- SSD 240GB Kingston V+200 A21 (SVP200S3/240G) (already was with the latest firmware)
- PSU Seasonic 400W X-400 FANLESS GOLD (SS-400FL)
- no CD/DVD
- no external graphics card
- mouse, keyboard
- monitor (tested LCD LG and Philips (digital/analog) and CRT Samsung (analog))
i.e. ideal system IMHO
The problem is when graphics drivers have been installed and the PC is restarted Windows always rebooted or BSOD-ed (with random codes) when graphics has been initialized.
Sometimes I can see logon screen for a second or two but usually it reboots right after the animated logo screen.
The behavior is the same for the all Windows I was able to find - Windows 7 64 bit and 32 bit and Windows XP 32 bit with or without the latest updates.
When I go to the safe mode and uninstall the graphics drivers then everything is good and stable - I did "burn", memtest86 etc. tests for hours.
What were done trying to fix this:
- tested all 4 BIOSes available including the latest 0049
- tested drivers from DVD, the latest from the download center and Microsoft Update and even for Windows8
- memory was tested with memtest86, MS memtest and from Windows using Sandra
- memory sticks were swapped, tested one by one and together, in the blue and in the black slots
- PSU was swapped with fully working Enermax Pro82+
- SSD was put into IDE and AHCI mode as well as plugged in into all 5 sockets
All above has no effect at all.
The only effect I can catch is when memory timings were changed to the slowest direction I be able to see logon screen for a couple of seconds more.
To summarize - when graphics drivers are not installed then the system is stable like a rock.
I am suspecting either CPU (it's GPU core) or motherboard.
Please help me.
