    Upgrade horror stories

    This computer upgrade horror story relates to my HDD horror story, which is in another thread.

    One day, I decided to upgrade my Pentium 100 to a Pentium 166 MMX. Of course, I needed a new motherboard.

    So after dishing out Australian $500 for the CPU and motherboard (a somewhat cheap one from a company called Spear), it was decided that my RAM would have to be replaced as well, since the new motherboard only supported EDO RAM. So a couple of hundred dollars went away with some new EDO RAM, and I finally brought my system home (after 3 business days of "upgrading").

    Unfortunately, the system still did not work at this time, since it would not boot at all, so I brought my system back to the computer store. They kept on saying this was a software issue, which may very well be, but they said that they did not touch the software so it isn't their responsibility (I thought that their responsibility was to do the upgrade and make sure the system works, at the very least - it appears they didn't even test the system after the upgrade).

    After hours of arguing about this, they finally gave up the fight and decided to fix my system - they wanted to remove my existing HDD and add a new HDD to it so they can install a new clean OS and test the setup - fair enough. Of course, they nearly wiped out my HDD, if I hadn't pointed out that they were trying to FDISK my current HDD, as opposed to the new HDD - they "wisely" decided to disconnect my HDD, just in case they did something stupid again.

    Anyway, after installing the new OS, everything was working fine, so they said I needed a new OS (I was using Windows 95 at that time, but they said I needed Windows 95 OSR2) - they wanted to charge me $150 for the new OS, which I saw was just an OEM CD (no box, manuals, license ...). I said no.

    It was at this time they re-connected my old HDD and found that it will not boot anymore, because it had been extensively damaged - along with all my data!!

    So a replacement drive was put in, I went home and re-installed everything, and it still did not work. I did manage to do some tricky things to make the thing boot into Windows, although my Panasonic CD-ROM drive would not work all the time now. I decided this was acceptable, and I really did not want to go back to that computer store ever again (as a side note, that computer store was later sued my Microsoft for software piracy, and fined quite a lot of money - I swear I had nothing to do with it - really ).

    Anyway, 6 month later I finally found out what was causing the problem - it was my CD-ROM driver. Apparently, the software engineers at Panasonic could not write a driver that worked on CPUs faster than 100 MHz - and it was only later that a 100 MHz + drive was released. Finally, everything started working fine, although the build quality of the motherboard was not up to standard (but that's another story ...)

    Moral of the story : don't upgrade your CPU/motherboard - small upgrades are okay, but CPU/motherboard means too many changed things, and you still have your old components in there anyway, which will cause bottlenecks. If you do need to upgrade your CPU/motherboard, just save up get a new system instead.

    If you need another horror story, there is one about my friend's upgrade of his IBM computer at another computer store. It was one of those with non-standard casing, and basically it was determined that his system could not be upgraded and that he needed a new system (and it only took about 5 hours to figure this out). Fortunately, the computer store guys were good guys, and they gave him a very very good price on a new system, and did all the work in one day (they were there at the computer store until midnight that day). Of course, the new system cost my friend double what he had intended to pay for, but I think it was worth it.

    It is fortunate that I learned to assemble everything myself before I started liking "computer upgrades." I've survived two major (CPU, Motherboard and RAM) upgrades without much trouble (The first one saw me plugging the floppy data cable in the wrong order, which was nothing to fuss about). Of course, prior to the upgrades, I always backed up my important files and prepared to reinstall Windows (Which is always the sensible thing to do in the case of upgrades).

    One particular small upgrade gave me the real headache and pain (I had assignments due in a few days and the damn thing would not work stably -> Frequent BSODs in Win2K!!!). One day, both of my 256MB PC2100 modules decided to fail simultaneously. I decided to purchase one 512MB PC2700 module (My SiS645 mobo supports it) to replace the dead modules. Upon inserting the RAM chip and starting up my system, it started up nicely and hell! it was noticably faster, esp. for 3DMark and encoding. One or two hours into the fun, the system froze right away. I had to cold-reboot. Upon rebooting, the system complained that no system disk was found. Somehow the boot partition (C drive) had been wiped out.

    I proceeded to remove the primary hardddrive and backed up the files in ALL partitions in that drive to another system. I also disconnected my other harddrives connected to the main system of concern (Just to play safe, as the computer store you went to did).

    I fdisked the primary drive, repartitioned everything and formatted the partitions. Installed Win98 in one of the logical drives, followed by Win2K in the primary partition. Barely through the installation, the freeze problem occured again and (you guessed it), I'm back to the "No system disk found" problem. I repeated the whole thing for two to three times only to keep coming back to square one. Exasperated and nearly losing my insanity (Mainly because I needed to sleep after the sleepless night I spent to finish another major assignment, and also because of the persistent problem).

    Two days went by without any progress, until I decided that something had to be done with the new memory module (I had no other DDR module handy at that time). My board happened to be a first-batch board, meaning that it still had bugs using PC2700 modules, which were still very new at the time of release. Using my other system, I went to the motherboard website and downloaded the latest BIOS release and flashed the board with it.

    Then I found that the latest BIOS had memory problems (3DMarks went down from 7500+ to 5000+), and that was after I reinstalled BOTH Win2K and Win98SE. Smiling to myself, although deep inside I wanted VERY MUCH to throw the f***ing system out of my windows, I proceeded to download the second latest BIOS release and flashed the board, destroying Windows in the process due to the changed ACPI structure.

    This time, I discovered the BIOS had the wrong DMI pool (No performance problem fortunately), and that was also after I reinstalled Win2K and Win98SE. I was stunned. I was ready to buy a new motherboard too. Fortunately, someone pointed to me to an alternative BIOS file (Same version), but with the right DMI pool. I was wondering whether I should try flashing the BIOS and re-do what I'd been doing for the umpteenth time. I decided to just do it, since I had become quite adept at installing Windows (Ever heard of crash expert course in software installation? I can now install Win98 and Win2K, complete with all software updates, in 40-60 minutes time). Fortunately however, my Windows installations remained intact and I'm still using them up to this day. The only catch is that I had to tone down my RAM timing down from fast to normal. The performance gain from the new module was reduced, though still noticably good.

    Never again will I want to do another memory upgrade, which was supposed to be just a simple task.

      I had trouble with a memory upgrade once. I was replacing 256 MB of CAS-3 PC-133 SDRAM with 512 MB of CAS-2 PC-133 SDRAM. That went well.

      However, when I went to put my old CAS-3 RAM into my older system (already has 128 MB of PC-100 SDRAM), something went wrong. No matter what I did, the computer would not boot. I even removed the newly added RAM, and it would still not boot.

      Thinking that I may have killed some other component in the PC while I was upgrading the RAM, I finally tried a last resort solution of removing all the RAM, and putting them back in a slightly different order. It finally worked.

      I still have no idea what went wrong, and I can only think that perhaps one of the RAM chips wasn't seated properly. Still, it took me the better half of the day to finish the upgrade.

        Theoretically, it is possible to mix PC-133 and PC-100 modules together. However, being a frequent poster in a PC hardware forum and having seen my friends with similar problems, I can say that it is very difficult to succesfully mix RAM modules with different FSB ratings. Computers are such complex beasts indeed.
