Diamond HD4850 1GB GDDR3

[jjeremycai]

I just built a new computer from scratch with new pieces (including monitor) yesterday night and left it there until this morning. However, the first time I ever booted it up, nothing showed up on the monitor. The monitor didn't pick the computer up. At first, I thought the monitor was broken, so I switched it to a reliable one I've had for a year. Again, same results. Then I changed the DSUB cable, same results. I opened the case and I took out the card and I put it back in, same results. However, throughout all of those tests, I've noticed one thing: on the graphics card (where I assume the problem is) there's a little red light that flashes up and above it in tiny print says overtemp. By the way, yesterday, I left all the pieces in the car, and they did get quite hot. Anyhow, I was just wondering, if anyone could post a clear answer, or better yet, a tutorial on how to fix this. If I still can't, I can still bring it back to the store for a refund, but I'd like to test my new computer first. The graphics card is a Diamond HD4850 GDDR3 1GB
Thanks in advance.

Welcome to the forums!

Make sure the six pin power connector is plugged in the Diamond.
Tell us if the fans and hard disks are spinning.

New build won't post checklist
