Please Help Monitor (and sound) go black after a while (Upgrade gone wrong)
What User Name
So I took this computer: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01549568&lang=en&cc=us&taskId=101&contentType=SupportFAQ&prodSeriesId=3793920&prodTypeId=12454 And started upgrading it. I bought a new rosewill capstone 550 watt power supply, and took out the old processor and slipped in a e8400 alnog with a new cpu HSF from newegg that is supposed to be pretty good.. Still running good. Got a 240 gig corsair neutron GTX SSD, and loaded windows 7 on it. Running good. Installed a saphire HD 7870 video card. Still running great. In fact, it is running skyrim fantastic! A week goes by, and now out of the blue, screen just goes completely black, monitor shuts down as if I pulled the video cable out. Also, a good clue, the sound cut out (using on board audio). No key presses, ctrl alt delete, nothing will get the computer to come out of the dead state until I turn off the power supply and reboot. Sometime ago, an issue popped up forcing me to buy a cheapie video (8400 nvidea) card to make things work. I wish now I could remember what happened, but it was a couple years ago.
Is there any utility I can use to find the GPU temps? Is there any utility I can use to find the CPU temps?
I figure it can be one of many things: memory, motherboard, my new video card, my new power supply, or the e8400 processor from ebay.
Where should I start?
I feel like throwing in the towel and ordering up a new copy of win 7, an I7, MB and ram. But I do have a daughter in school, and it may be a bit impracticable.
