Question

Boot problem - Post Code C1 - Initialise Post Error Manager (PEM)

Asked by: CSHTech

I am trying to sort out a desktop system whose issue was blue screen spontaneous reboots. On boot, couldn't get into the OS, even in safe mode.

Ran Memory test on the 1GB stick and it failed 5 out of 6 tests. Replaced with two sticks of known good RAM. Initial test results showed failed 1test/passed 5 then passed all 6. Still no access to OS on boot - rebooted every time. BIOS display showed only one stick present, though.

Reseated RAM (tried one stick only in slot 2 to see if it would boot into OS) and now get continuous beep. Post card shows error code C1 - Phoenix BIOS lists show this as "Fail to initialise Post Error Manager (PEM)".

All jumpers and connections are correct and this happens irrespective of which slot the RAM is in.

PSU is fairly new.

ESys mobo P4M800Pro-DDR2 with N15235 printed on the board itself.

Any thoughts on what this could be? Is the mobo on its way out?

Thanks.

Further info: -

The BIOS chip on the mobo has a Phoenix BIOS sticker on it, but the Esys website specs for the mobo state that it has an Award BIOS!

If this is the case then the C1 error code means memory detection error.....which bearing in mind the above, would indicate that the mobo has a major problem.

Any advice greatly appreciated.

possible that there's some problem with the memory slot. possible that the gold edges on your ram are dirty. take a clean white paper and wipe the golden edges of your ram modules and put it back on your ram slots and try to power on your pc again.

CAUTION: this process could damage a working ram chip. do at your own risk. still, i've used this method thousands of times and never damage a good chip. take necessary precautions like grounding yourself before touching any naked pcb/chip on ram modules, motherboards, hdd, etc.

if the system won't start, you have a bad mobo on your hands.
the only thing to narrow down the problem is the minimum setup :
Here my troubleshooting procedure :
i suggest testing with the minimum setup - disconnect also all peripherals and network cables :
motherboard + cpu + 1 ram stick, video card, power supply
verify that the 4-pin cpu Aux power plug is connected
on boot, do you have a display?
if NO it is one of the connected, swap ram, Power supply, video card or monitor - leaving only motherboard and cpu
if Yes, add devices till the problem shows

you can also check the motherboard for bad capacitors as shown here :   www.badcaps.net
