alright, so, when i went into frys today (i work at palo alto frys in components), i got to talk to our service department head, and he seemed to agree with my diagnosis of the problem, and the possibilities for what to check when and how.
1: this comp's northbridge cooler had a fan, and i say had because it is DEAD, since the bearing is full of dust, and its pretty much completely locked up. fortunately, i actually still HAVE a spare northbridge cooler i was using when the cooler on my old 750MHz Duron board/cpu went up in smoke (completely fused), and the retaining bracket on the stock cooler is identical to the one i need to mount the old cooler, so i can fix that.
2: if the northbridge isnt cooked, or at least a little crispy even, this should hopefully fix my memory error problem. if it doesnt, this comp gets to eat memtest all day tomorrow with different memory settings and configurations until i find out why its erroring. hopefully that should fix this issue
3: if #2 doesnt work, this comp is getting its PSU pulled and were going to have a meeting with my multimeter, as well as a full system tear down/clean up in the process, just since it needs it, and a full capacitor + magnifying glass run
4: i think the other drive that was in the comp, the one i havent imaged yet and was having trouble defraging, is also dying, which isnt a problem so long as i can image it since i was going to replace it with another used drive that still has some life in it (i havent checked it 100% yet), which should solve that problem.
5: pray?
6: i had someone come into work today looking to buy a socket 939 motherboard, but the only one we had was $80, and it looks like he is going to just buy an AM2+ board and an athlon X2 7750 Kuma at my recommendation, and he is welling to sell me his old X2 processor if he replaces the rig. i can use this as a drop in upgrade for my old rig's 939 athlon 4000+, since even a 3800+X2 would be faster in new multithreaded games (which said friend plays), and chances are for what he paid when he got it, this one is at least a 4400+. if i buy said CPU i can talk to him about working out a payment plan for the cost of the CPU, case (brand new CM 690), and graphics card (like new HD4670). even if this isnt an option for them, i was half ready to look into giving the rig away to him, its just that again, the case is brand new and it would need an up to date GPU, since the one in this old rig is an AGP x1650 512mb.
as for parts to test the rig with, the 2 1GB sticks of DDR400 i have in my 939 rig should work in the old motherboard, since they both run DDR400, i have spare power supplies and graphics cards. the only thing i cant swap out directly are the CPU or motherboard really. this system honestly should just get replaced, but somehow he is managing to play farcry 2 on it (dont ask how), and if it means less work for me and no cost for him, thats pretty much the quickest outcome i can get him. its just a pain in the ass and what not. as soon as all this shit is over and done with, i get to go and do a clean sweep of the OS, because it turns out he has a bunch of trojans he cant get rid of, that he got since last time i gave it a checkup, and all the standard ways of getting rid of them just dont want to work, either for me or 2 other guys who he talks to first, since he sees them more often.
well, its 7 am, and i been up all night on monsters watching episodes of supernatural while i hammer away at this thing one bit at a time, and im about ready to pass out. hopefully i can get this fixed by the end of the week.
