Hello and thanks for any help in advance. I have a home built Phenom II X4 2.7 (Comp. Specs on my profile) which I was using an ASUS M4A785-M MB with. Last week my computer started freezing up at the BIOS screen. I removed all RAM and checked for diagnostic beeps. No beeps. I put one stick of ram in at a time, taking the ram out and putting in a different stick each time. It still did the same thing. I removed all cards and used the on board and it did the same thing. I bought and installed a new 600 Watt thermaltake and it still did the same thing. I checked for possible grounding issues, there were none. Today I took the RAM and MB to be bench tested and both were OK. I had ordered and received a new MSi 785GT-E63 MB and installed that tonight. I set everything up and installed everything properly and double then triple checked all connections and hardware. I powered up and it did the same thing, only this time it doesnt make it to the BIOS screen, it freezes at the MSi splash screen before the BIOS screen. Before I installed this MB I took it and had it bench tested to make sure it was good before I did anything further. Since installing I have gone through all the same things as mentioned above with the ASUS and it does nothing, just freezes. I am at a total loss for an explanation. Anyone have any other things I might try? Thanks

hi TankerHC

thats quite a problem you got there.
looking into the hardware side of things too..
maybe there are some electrical ground happening in some other component

maybe check:
1. your video card -- assuming you are using a pci addon card?
2. your lan connection -- maybe test with the lan cable unplugged
3. usb extension wires for the cpu casing
4. cpu casing wires and any additional fans
5. dvd/cd drive?

basically, im also thinking the same thing about connecting as few devices as possible to make sure they are not causing the bios lock-ups.

It may not be this, but I ran into the same problem where it would freeze at the motherboard splash screen and I had just been re-configuring some hard drives, so I unplugged them all and it got past the splash screen, plugged one in at a time and restarted, found the culprit, changed the Sata cable and then it worked the first time after that. It's a long shot, but sometimes if the cables are bent too tight around corners, or if it has a slight defect which does happen, try that next time. Just another troubleshooting tip.
