intel board d845gvsr lost all visual

I used my pc for 4 yrs now. But now it has stopped working. It starts but no video. Just black screen. This happened after i changed RAM. Shall i scrap it or there is any hope? Any clue?

Restore the CMOS settings and go back into the BIOS to restore conservative RAM timings. There's a jumper on your board to do it, find the manual for your board on Intel's website unless there's a printed version at hand. It could well be that your previous RAM was using tighter timings that this new RAM can't handle. Another reason might be voltage. That Intel board won't let you change VDIMM yet your new RAM might be unstable unless it gets 2.6V instead of 2.5V. Lowering the RAM timings as above might let you overcome this hurdle though.

Do you have a PC speaker connected to the board to hear any beeps? Or perhaps a port 80 debug card? Probably not. How many DIMM's have you put in? I believe that board has 2 DIMM slots. Remove one memory module and retry.

Either faulty RAM, incompatible RAM, or too strict timings. Any DDR should run find at 266MHz at 2.5V but not necessarily at CAS = 2.

Thx first.
But the case is as I stated and I tried replacing the previous RAM but it doesn't work. No beep speaker sound. But when I press START, it sometimes starts and after loging in to windows or just before that, The display will bshshhh and black screen again. I suspected that may be I have blown some component with a static electricity. Now that the cost is about 1third of my salary. And I would be glad if I could someway fix it.

Sometimes starts....

Sounds like something with the DIMM slots has gone wrong. Did you perhaps at one time put in the DIMM the other way round (which is nearly impossible to do)? ....and then powered on your system. You would have had some smoke, which in turn would damage the DIMM slot so whatever RAM you put in their now, it won't work without errors.

Did you try trying just 1 DIMM now? In either of the slots to see where that leads you?

After I dealt with the jumpers the system worked for 3 hrs. I was very happy. I restarted it and turned it off and turned it on just to make sure that it is restored back to normal. Then when I started it up the next day the problem was still there. It startsup but No video-third day now just like that.
The ram can not get in the other way no matter how you try. I am also using only 1 ram.

I would really aim to try out different RAM that follows the JEDEC standard to the T. I think it's a voltage issue but since you can't bump it up on this board, the memory is flaky or otherwise not stable. DDR by default operates at 2.5V and this is the current supplied by this board.

Either this or remember to lower the RAM timings in your BIOS to 3-3-3-8 instead of 3-2-2-5 for example. The higher the number, the more latency cycles to access the RAM hence more stability and lower voltage.
