Can a chip get hot/warm if its bad? 8450 related

[greyclear]

Back story. Old 8450 X3 system that I had doesn't stay powered on long enough to troubleshoot what might be the problem. It comes on but goes right off. I tested the power supply with a tester all values are good. I pulled out parts and started putting them in one by one to test but same result. So I bought another MB and it stays on but nothing is on the screen. The nvidia card (9600gtx I think been so long I forgot) the fan runs at 100% so I swapped that out with a standard ATI PCI card. No beeps and with or without ram nothing posts to the screen.

But the processor, gets warm and warmer the longer you keep it on. So my question is can a processor still exhibit this behavior even if it is bad? The MB might be in question I did get it refurbed since it is hard to find AM2+ boards but I trust the seller so it's 50/50

Have you tested the PSU while it is trying to power the system? It might still put out the right voltages when unloaded, but fail to do so when loaded. If that's not the problem then I would think that there is a problem with your refurbished motherboard. The CPU is the most reliable essential part in a computer. They almost never go bad, especially without major increases in voltage, and that usually makes them die slowly, not suddenly.

Did you check your ram ? try clean the golden contact a bit , it may help
If you plug in more than one RAM, try only use one and different DIMM slot

Sometimes ago my old Phenom X3 8450 have failed one set of IMC and refused to boot , I have to use DIMM 1 only or it won't boot at all

Lets hope it isn't your CPU died

the fact that the cpu is getting warm means it's getting power. i kind of agree with the ram theory have u tried 1 at a time? diff slots? double check wiring to ensure you have no shorts. tried diff hdd's? last but not least try clearing cmos.

Power seems to be good. The ram I checked one at a time in SLOT 1 but I did not try the other three slots one at a time. I might pick up just one brand new stick at the end of this week and try it again. I appreciate the help

[i found nemo]

ok well be sure to try it in diff slots, something good may come from just for trying it out. it's true about those chips dropping mem controller channels... the more i think about it the more it fits in. but you need to test all rams in diff slots 1 at a time. how many sticks do u have btw? i've had 2 sets of ram go at the same time, and it made testing more difficult.

Sounds like a MB problem, although it could be the PSU (under load)...
Have you checked to make sure the HSF is mounted properly and seated well with an even spread on the paste?
That's probably not the problem if the heatsink is getting warm, but it's worth a look.

Another thing you can do is pull the board from the case and test it on a piece of cardboard.
I've seen situations where the brass standoff's have been shorting out to the bottom of the board causing similar problems.

If you live near a MicroCenter you can pick up a nice combo deal with MB and a 4gb kit of DDR3 1600 for <$250 (including an FX-8320 or 6800K).
If you can't find the problem that's a better option than throwing more money at such an old system IMO...
