*normal boot up* *WinXP(Pro) Logon screen* *sieni enters his password* *Jingaling Windows start up song, which is unkewl* *BEEEEEP ERROR sound* I've tried googling around a bit, and what I've done so far is checked my administrative logs (System and Application logs) and ran MemTest, but neither helped(meaning no errors that would explain what has happened). So as I hope my reenactment explained my situation, I get an annyoing windows error beep right after the Windows Start Up Song, and I have no idea why it is happening. I just upgraded my computer with 2gigs of ram, a new sata-hdd and a new gfx card. I also OC:d my processor, but with such a minimum amount that it atleast shouldn't affect anything. Just for the record, I have 2 HDD in RAID0 now and 4gigs of ram. The error beep started happening completely suddenly. I had installed all windows updates and everything was running fine. Then something went wrong with my firewall (Eset Smart Security), it didn't let me use any web browser while on, after I fixed it is the approximate time I started hearing the beep, but I'd guess it has nothing to do with that, perhaps I only now noticed it as I usually use earphones. DXDIAG: http://paste.servut.us/4ry5 Can anyone help me? Thanks :3 -- EDIT: I think the screen flickers just a bit during the error beep. -- EDIT2: It could be a coincidence, but I had a crypt32 error around 6am(gmt+2)... -- EDIT3: http://paste.servut.us/y1e2 <-- ntbtlog.txt -- EDIT4: Confirmed, processor OC had nothing to do with it. -- EDIT5: Pretty sure that it's not a RAM prob. Disabled fast boot in bios and let it check my memory. Reported it to be fine. -- EDIT6: Installed WinXP from scratch, problem solved. I win.
