I have an assembled PC, it was working fine since 18 months. Now, I tried to upgrade its RAM and as it was mentioned on the mother board DDR1, DDR2, so I got a DDR2 RAM of 1GB and inserted in the free slot. The 256MB RAM already existed in the DDR1 slot. The DDR2 did not fit properly in the second slot (one end was fixed and the other was loose), but I went on to power the CPU, there were fumes coming out and I switched the power off within 2-3seconds. Later I checked with the DDR1 RAM, it fits in the second slot as well, even though it’s mentioned DDR2 on the motherboard. But now when I tried to power the CPU, it gives beep (Alarm) sound continuously and there is no display on the monitor. the Processor fan is running smoothly, I checked the battery, even that’s working fine. Please help…
My system configuration
Celeron Processor 2.53Ghz,
RAM 256MB, HDD 40GB,
