What am I looking for in CPUz? It can show you the processor voltage in Windows as well as the bus speed. What I meant was the components which drop the 3.3/5/12V (whichever rail is used) to the CPU's voltage (~1.5V) and stabilize it. In the BIOS: CPU Temperature 43ºC/109ºF; M/B Temperature: 22ºC/ …

If you want to try it yourself there are a lot of how-to solder videos on YouTube. Decent inexpensive irons are sold at RadioShack and Frys. The parts are pretty inexpensive http://www.digikey.com/product-search/en/capacitors Search for Aluminum/Aluminum Polymer caps. Usually motherboards use 470uF, …

Or there could possibly be a power stage on the motherboard failing to supply enough current when more things on the CPU activate. That seems unlikely as the same problem happens with 5 PCI cards + 4 HDs connected, or with no PCI cards and just one hard drive. What I meant was the components which …

Try IntelBurnTest, SuperPi, Sandra. Also see what CPUz tells you. What is the CPU temperature while idling? Is its voltage correct in the BIOS? When running a stress test, measure the 12V rail from a 4-pin molex and see if it is dropping too low. Or there could possibly be a power stage on the …

That's a really cool motherboard to have, but Tualatin was never on socket 478. DDR1 never had a triple channel controller. Using 3 DIMMs disables the dual channel ability and they will all run in a single channel. The motherboard and 2.8 Northwood are the same ages so you already have working parts …

A storage controller always needs a driver, so I'm looking into what makes your scenario true. If I research something ubiquitous, like the SIL3114, the driver support officially starts at Win98SE. It looks like it bridges from the SATA interface and situates itself in Windows as a Bus Master IDE …

I am thinking of getting an IDE/SATA adapter with it if that is important. The 500GB drive in the discussion is SATA? Windows 95 probably won't have drivers for that. Or for anything else in your system, if your motherboard is new enough to support SATA onboard. If it is a PCI card, it will …

the thickness of the oxide gates (transistors) before they breakdown keep everything with in a safe range when it comes to the temps. Yes, because of this, old 500nm CPUs will operate far longer than newer 22nm ones--I'm not making this up. Though newer CPUs have many more thermal safety and power- …

You could get an LS14250 with axial leads and reuse the 4-pin female 0.1" connector. Cut off the dead battery and strip back some of the wire. Wrap the wire around the new battery leads and cover the exposed wire with electrical tape or heatshrink.

Just a guess, but the switches are probably for toggling between NTSC/PAL video mode. It could be that an RCA CVBS output is on those pin headers.

I'm puzzled by this. Can or can't DOS Box apply scaling algorithms to upscaled resolutions? Could the 320x200 be upscaled 5x to 1600x1000, and then that 1600x1000 is the data which is used to do like a live bicubic (or some optimal nice looking algorithm) to stretch it into 1600x1200? Otherwise if …

Use a solder pot or a heatgun. The slot is bad anyways so melting the plastic won't matter. Just don't hit the adjacent slots! If you do this correctly, with a matching part, and it tests working, don't even mention you replaced the slot. It's extra info practically nobody needs to worry about. …
