Hello, This is my first time on this forum and I can see there are some very tech savvy people here that could possibly help me. I built a new system, and it just keeps getting progressivly worse...but I am not sure why... ... there is so many little things that are odd and I cant pin point the exact the problem. I have placed this is other hardware because it maybe many different hardware problems... or just one... I am not sure. This is my system specs: -AMD Athlon 64 x3 4600+ Manchester 1ghz fsb socket 939 dual core -ABIT Fatal1ty AN8-SLI Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard -2X BFG Tech Geforce 7800GTX -4 gigs of ddr ram (CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM System Memory and OCZ Titanium 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel) -Maxtor MaXLine III 7L300S0 300GB 7200 RPM 16MB Cache Serial ATA150 -2X Western Digital Raptor WD740GD 74GB 10,000 RPM 8MB Cache Serial ATA150 (Raided) -Plextor 8M Cache SATA DVD Burner -Windows XP sp2 (32 bit) Alright that sets the battleground. My first problem is that things randomly start to slow down then crashing, or if I listen to music it randomly starts repeating quickly... then if I let it go its ok. . Lately though it has just been crashing after words. or now it crashes when I play videos at random moments. I hear a clicking from my western digital drive before it happens. That clicking makes me uncomfortable. It may be my raiding maxtors... but I am not sure. Sometimes though it pops up with a blue screen saying it is dumping my physical memory and a error. "Driver_irq_equal_or_Less" and at the buttom it gives the driver "nvata.sys" (Nvidia driver) with the hex numbers. I am not sure of what to do, I been searching for solutions with no results... The problems could also be with my memory. I have 4 gigs installed, and 32 bit windows only shows 2.5 gigs. I have set may paging to zero. When I use torrents online now, it gives me an error called "Delayed windows writing" and then the entire computer freezes. I am not sure what that means or what it freezes. It used to work fine a week ago. My seta dvd drive lost its ability to burn dvds using encore, and when I burn regular data dvds it gives me errors after verifications. It says sections didnt match up. Here is some more random information, Some games like, knights of the old republic and psyhocnauts, they start to speed up like crazy and the (only kototr) starts to lose lights and can only see the shades while you run into walls and such. I am not sure if taht is anything. My main point is my system is unstable, but I am not sure why. -Video card drives screwy -My hard drives are not synched, or faulty -Seta drive dvd is causing problems with...something -Memory confusion, wrong paging, cache messed up? It could be motley of these things. Can someone just help me with some suggestions? Any start, is a good start.
