nothing on screen, motherboard power on

Screen just went blank , pilot light on monitor blinking,  m/board light remained on. Appeared as though no activity from drives, turned main switch off. Restarted, only 1 long  & 7 short beeps. Moved memory to another spot,  Ok. Shortly after same problem, again,  same steps to remedy Ok again. O/s w7 working ok. Frustrating. Not  crashing, no blue screen, no messages

Try reseating your Video Card and check the cables are seated properly.

Please provide mobo manufacturer and model we we can check what that beep code stands for. Also if you think it could be a memory module try to remove it, not move to another slot (in case you have more than one). For RAM you can try to boot MemTest+ and run it to chcek memory.

Foxconn Renaissance 2,   9 months old. I had 2 banks of 2gb DDR3 memory before this problem occured. I have removed one stick, but the problem has continued

Always run memtest 86+ when you suspect bad RAM. You'll find it on the UBCD:

Make sure your system isn't overclocked. Make sure the fans run smoothly. Also ensure the heatsinks are firmly and properly attached so there is no overheating.
