Hello glorious Tom's community! Just finished a new build; but the computer will only boot when it's on its side. Once it boots on its side, I can stand it up and it performs flawlessly. I've done some research, and I've come up with a couple of sources to the problem:
1. There is a loose screw banging around behind the mobo (I highly doubt it, I've looked and I can't hear anything).
2. The CPU isn't seated correctly. (I'm a little wary of popping it out and re-seating it; having $320 dollars worth of CPU in my hand scares me)
3. The power cords from my PSU could be kinked in a way when the computer is upright that limits power to the mobo/components.
4. I'm running 2 Radeon 5870's in CrossFire, which I'm told could be slipping out of the PCIxE slots; i.e. something weight related?
Does anyone have any input on what this problem could be? I'd greatly appreciate any suggestions at all; this problem is extremely annoying. I'd like some feedback before I try to re-seat the CPU or mess with any wiring. Thanks in advance!
Here are my PC specs:
Windows 7 Professional 64-bit OS
CORSAIR 1200 Watt Modular PSU
ASUS Intel Z68 P8Z68-V PRO Motherboard
i7-2600 Sandy Bridge CPU
Kingston HyperX 8GB RAM
2 x Radeon 5870's in CrossFire
CoolerMaster HAF 932 Full Tower Case
Samsung 1TB 7200 RPM Hdrive
I'd be afraid of running the system that way long term without finding/fixing the problem. If its a short in PSU, wire pinched by MB, etc. then when it finally hits you it could take a lot of parts with it.
Alright, it's a CPU problem. One of the connecters that snaps the heatsink/fan into place on the i7 won't properly snap in. I messed with it for a while and I think I got it snapped in all the way, but when I boot now it says that my CPU temp is overheating, and just shuts down.
I must have read it wrong, I guess it was 97C, which is like 206F. Very very hot. I had to reapply the thermal past a third time; I guess I used too much the 2nd time. After reapplying 3 times, i made sure all 4 of the heatsink clickers were snapped in, and it now boots standing up. An insanely hectic and stressful day, thank you for your help!
