I have a Dell XPS 410 and recently been having problems with the Ram memory modules. About 3 months ago computer wouldn't boot and diagnostic lights 3&4 were on referencing 'memory modules are detected but a memory failure has occurred' per owners manual. I removed both modules and replaced one at a time in the first slot and was able to figure out that one of the modules was bad. Computer was able to boot on one module. I ordered two new modules and computer worked fine with the new ones in. Then it happened again, one of the modules was bad. Looks like it overheated as the label was partially melted. Ordered two more but only put one in. Worked for a few days then one morning it did the same thing again, computer won't boot and diagnostic lights 3&4 came on. Replaced module but this time it didn't work. Again this new module also had the label melt. After reading a lot of forums online I rebooted computer without the modules in and diagnostic ligt 1 came on, per owners manual 'no memory modules are detected'. I reseated module, checked all wires, cleaned any dust but does not boot up. module just gets very hot and start button light is a solid amber with the diagnostic lights 3&4 on. Only thing I can think of is the motherboard is bad. Could it be the mobo? Don't want to buy a new one if it is something else. Here are the system specs:
Dell XPS 410 Pentium D processor 820 with Dual Core Technology (2.80GHz,800FSB), 2x1GB Dual Channel DDR2 SDRAM at 667 MHz, 250GB Serial ATA 3Gb/s Hard Drive (7200RPM) w/Data Burst Cache, 256MB nVidia Geforce 7300LE TurboCache.
Any help would be greatly appreciated.
