I just recently bought new parts and built a pc. This is the first one I have built but I had some help from friends in the process. Here's the stats on the computer I have in hopes it helps solve my problem: ASRock 939Dual-SATA2 Socket 939 ULi M1695 ATX AMD Motherboard CORSAIR ValueSelect 1GB (2 x 512MB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Kit System Memory AMD Athlon 64 3200+ Venice 2000MHz HT 512KB L2 Cache Socket 939 Processor Western Digital Caviar SE WD1600JS 160GB 7200 RPM 8MB Cache SATA 3.0Gb/s Hard Drive - OEM eVGA 256-P2-N553-AX Geforce 7600GT 256MB GDDR3 PCI Express x16 Video Card ****** ****** When I first setup the computer everything worked fine, but I got a Trojan Virus called cmdService and was unable to reslove any issue with that. I used Hijackthis, Ewido, Spybot and Norton Antivirus and all were unable to delete the virus. Despite that issue the system still worked fine. I had also had frequent Audio problems where the sound would just stop working. I went through many troubleshooting options to get it working again and sometimes it would work but then it would stop again. I read through several other forums and I think some lead me in the wrong direction. It now took about 5 minutes for windows to startup after login and I got these two error messages: ALi 5289: Windows Sockets??? RUNDLL: Error loading w08b4021.dll The specified module could not be found. I restarted the computer and reinstalled the OS (Windows XP) but it didn't solve anything. So I decided I would simply reformat my HD by using the Recovery Console on my Window XP CD. I don't remember exactly but I went through some steps so I could use the recovery console from boot (it gave me the options: Start Windows XP OS or Start Windows XP Recovery Consoloe). After starting up the recovery console I got this message: A problem has been detected and Windows has been shut down to prevent damage to your computer: **STOP : 0x0000007B** (0xf7c7A524, 0xC0000034, 0x00000000, 0x00000000) I went to run CHKDSK but I got this message: CHKDSK cannot run because the volume is in use by another process. Now after rebooting the OS no longer starts up. Either the computer goes into a continuous loop of starting up and restarting or, if the windows xp installation disc is in, it will boot up with 3 options: 1) To setup XP press ENTER. 2) To repair XP press R 3) To exit without installing XP press F3 Pressing ENTER to install windows xp gives me the option to press F6 and install 3rd party SCI or RAID drivers, so I got onto my older computer and dl'd the drivers from the ASrock.com website and burned them onto a CD > restarted the computer and hit F6 when I got this option again.. but it wouldn't load these drivers when I put in the disc. I assume I need to do it from a floppy since it asked for the A: drive... but I have neither a floppy drive or discs for that matter. When I choose repair from the 3 options listed above I get this message: Setup did not find any hard disk installed in your computer. Make sure any hard disk drives are powered on and properly connected etc.. So this is where I'm stuck at now. 2 days of reading through lots of forums, messing with and messing up my computer to try to get it fixed and I'm stuck with a new pc that cycles through startup and restart w/o the windows installation disc in the drive and tells me that no hard disc is installed when the win xp disc is in the drive. Any help on this would be greatly appreciated. Thanks in advance for any help with this. I'll be checking this topic regularly so if you need any more information I'll update ASAP.
