Ive been browsing the forums but haven’t found the answer to my problem. Im new here. First ill start by listing my components. I just bought a barebone system from American pc and it came in yesterday and ive had nothing but problems with it. New: -Asus K8V SE Deluxe -Athlon 64 2800 -Rexpower 450watt powersupply -new case Stuff I am just adding to the barebone: -PNY Verto GeForce FX 5700 LE Optima 128 DDR AGP -generic floppy drive -sony dvd drive -samsung cd RW -2-3 year old Western Digital 40 gig IDE hard drive -a 512 stick of PNY 2700 DDR Ram (few months old) -a 256 stick of generic brand DDR Ram may be 2100 or 2700 DDR Ram (2-3 years old) Ok my problem is I cant get into windows. I just figured I can unplug my HD from my computer now and put it into the new one. Didn’t format or partition, still has everything on it that I have been using, ie, games, apps… After I start the computer, the bios checks itself, finds the HD, finds the ram, graphics card. All is found during bios check. Then the HD makes a sound, screen goes black for about 5 seconds, then HD starts to spin up again and I am given the choice between Microsoft Windows or Windows XP. The reason I have a choice is cuz I am not running NTFS, just FAT 32 and using a Win 98 boot disk was the only way I could do this. So it sees Windows and XP but windows O/S is not there, just XP. So I choose XP and then I get this blue screen that says: “A problem has been detected and windows has been shut down to protect your computer If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps: Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Fun CHKDSK / F to check for hard drive corruption, then restart your computer. Technical Information *** Stop: 0x0000007B (0xF894E640, 0xC0000034, 0x00000000, 0x00000000)” I have run memtest for 7 hrs straight. 3027 cycles and 3719% coverage. No errors. My bios Revision is 1004. I am using the HD I am having problems with in my new system, in my old system now. It works perfectly. No viruses, all data there, nothing is wrong with it. The new system just doesn’t like it. Help, im lost.
