Brief history. I built a W7 machine a few months ago, and overall it has been working pretty well. I noticed shortly after purchasing that I'd occasionally have problems where my system would entirely freeze up (I thought it was the so-called W7 black screen of death). This would happen about 1-2 times a week.
Things got better and I didn't notice any major problems until last week when my PC froze about 15 times in a 4-day period. Things got better again for 5 days until today. Now I can't even get the machine to boot into Windows at all. The PSU will power-up the machine, but all I see is a black screen. I thought it might be my power supply, but I tried a spare I had and that didn't work either. I'm pretty sure now that it is either my video card or my MB, but don't know for certain. If I disconnect my monitor from the video card, I get the standard notice that the monitor is disconnected, but I'm not sure if that eliminates a video card problem.
Unfortunately I don't have a spare MB or video card to use as a tester, so I'm trying to pinpoint as much as possible. I'm inclined to say it's a MB problem at this point, but these problems are tricky to identify. Does anyone have any ideas?
My first question is "PSU will power-up the machine, but all I see is a black screen"
Do you have post? in other words does the bios screen show up, if not spinning fans are not a sign of power-up (opinion).
If system is dead just spinning fans things you can try:
disconnect unneccesary devices, leaving you with just keyboard/video/one stick ram. Clear Cmos as per manual, attempt startup- if post screen bios comes up your on your way and more advise from that point.
If nothing at that point it will be difficult to identify Mboard /video/ram without backup components. Also if you have an old system speaker somewhere and hook it up maybe it can identify problem for you.
I have the same problem.. almost the same build. Have you come up with a solution?
I can access and tweak bios, but once it tries to load the operating system, all I get is a flashing "_" in the top left corner.
I've disconnected all devices like you said, cleared cmos, tested memory sticks one at a time, swapped video cards, and still nothing.
I've gotten win xp to run off an old IDE HDD, so I'm convinced my RAID 0 array has gone bad. I'm putting off wiping that for last.
