Hi, tried on another forum but nobody could help, maybe I'll have more luck here. Basically I added 512 ram to my self build pc which already had 512 installed. The ram was exactly the same as the ram I had installed (KIngston PC3200) and the motherboard is Gigabyte GA-K8VT800. After installing the new ram the pc gave a series of long beeps indicating ram error. I took it out and the computer booted fine with only the original ram. Tried the new ram on its own in all 3 slots and again the error beeps. I assumed the ram to be faulty but on booting with only the original ram I got the same error beeps again. Nothing on the screen, only constant error. Took the new ram back to the shop, the guy there replaced it and said I should reset the cmos and the original and the new replacement ram should work fine. The reset cmos is a bit strange on this mobo so eventually I took the battery out, left it out overnight and still the same beeps with both the original ram and the replacement on their own. Has anybody else had similar experience? Has the motherboard bitten the dust? Will take it to the shop tomorrow but just wanted to know if anyone could help before I do that. Thanks
