In recent days, I found a case for sale at an attractive price, I perfected the purchase and used it to put inside one of the many PCs that I fixed (long ago). In addition to the case there is the floppy reader, currently it is not yet connected, it is there to fill the hole, but I should have a …

I got to test one of the MBs where I had changed a couple of capacitors, it is the Supermicro Slot1 with Intel i820 chipset (chimney), before the replacement it was put away because it had a problem, it stopped working after a while, I thought it was due to two swollen capacitors, but I know that …

Ordered a batch of motherboards yesterday, three ASUS and one ASROCK. Looking in detail these are cards from the mid-late 2000s, The ASRock is a socket 478 for Pentium CPUs up to Prescott, it has some capacitors to replace in the area near the CPU, the exact model is P4VT8 +, I have a working one …

The batch of motherboards shown previously arrived a couple of days ago, when I opened the package I had a pleasant surprise, the motherboards purchased were four, but those arrived are five (the fifth for free), the fifth card is a MSI MS-6741 SKT 754, apparently it seems ok so it is likely that it …

The 9200SE is AGP 8X, the Radeon 7000 I don't know if it's AGP 8X, but looking at the position of the slots, it looks like an 8X too. I'm afraid that Radeon started supporting AGP 8x from R300 core (9700 and 9500) and later with RV280 core (9200/9250). Even Radeon 8500, the best chip of R200 core, …

Order two AGP video cards today, nothing fancy but they were particularly cheap, and given the low price I ordered them. They are both from ATi, one is a 32MB DDR Radeon 7000, the other is a 128MB 9200SE, both have two VGA ports, one normal and the other DVI. One has a third video output, I think …

Very beautiful those thermal images, I think they can be useful but only if you can highlight strange temperatures, that is higher than normal. Now I do not know exactly what it is to not start the PC, sure that strangely cold Chip could make us suspect a failure there. It would be useful to check …

Finally an update to this topic! I did my homework and replaced the Varta 3 battery with a somewhat more modern NiMH counterpart. In fact the old NiCd happily charged up to 3.6V on my hobby charger 😀 Also had to resolder the ceramic decoupling capacitors sitting underneath the CPU package since …

Hi, by chance I found your post, I have a VLB controller same as yours, but it has a malfunction, the problem is that the PC freezes, I later found that the freeze is caused by a missing capacitor, to be precise it is C20, it is located next to a J1 jumper, it is of a similar type to the other one …

I change motherboard type, this time I have a Barebone PC board, it is a BIOSTAR M7NBA VER: 1.2, the board had a couple of visible problems, a missing SMD capacitor, and an electrolytic dented on top, not knowing which SMD to use I removed it and welded one at random (from a scrap MB), while for the …

The 83MHz FSB bus however is another story, most devices won't be able to handle it. The PCI bus runs way too high at that speed courtesy of lacking a proper divider. Like I mentioned above, this board's clock generator has the ability to run the PCI clock at a constant 32MHz independent of the FSB …

I fixed the ATX Super Micro card, i820 chipset plus MTH for PC133 ram, with Slot1 PIII 500 CPU, the video card is an AGP Intel i740 I think 8MB, the audio is integrated. The problem he had is the PC freezing after a certain time from starting, I do not know if it was due to the swollen capacitors, …

In the last few days I have looked for the missing SMDs of the BKi810, unfortunately I do not find the 76C and 18C resistors among the scrap boards, those marked 472 are very common and are present in all the boards, since I cannot find them, for the moment I do not I can perform the repair, so I …

Since I have used this CF card in other PC I already know it's CHS values, it's also formatted under DOS with DOS installed and working under other PC. The problem is that, this bios does not allow to set CHS values, all it has when it comes to HDD types is selecting from 1 to 47, where Type 47 …
