thnx very much for the technical info...how about mobo for AMD K7 processor, naa kay available diha? thnx again...

[mr.suavi]

pla pa au sa hardis na 20g?? dli na cya madetec kai mu hang man imu pc kung imu ita.od hehe...

pm.. kung pla price og kung ma.au paba ni... pang masa na price sir ha??

TO ALL WHO ASKED IF YOUR HARD DRIVE CAN BE REPAIRED OR NOT:

I can only say YES or NO after I have diagnosed the drive (desktop or laptop HD).

My success rate is 7 out of 10 in general. I mean, 7 of 10 hard drives submitted for repair were fixed. And none of those drives repaired were returned for repeat service so far.

If your hard drive is really hopeless after my diagnosis, then at least we have tried. Anyway, I don't charge anything if I haven't fixed it.

FOR MOTHERBOARD REPAIR, MY SUCCESS RATE IS 9 OUT OF 10.

SOME HELPFUL TIPS ON HARD DRIVES:
1. Drives that cannot be partitioned or formatted have physical bad sectors (not logical) that need to be remapped/wiped out so that these become hidden from access by any Operating System.

2. Wiping out bad sectors and hiding them from OS access certainly reduces your drive's capacity somewhat, but that is negligible compared to the total size of the drive. For example, if we wipe out 10 physical bad sectors that is only 10x512bytes or 5.12MB which is very small compared to 4.3GIG, etc.

3. It is normal for hard drives to develop physical bad sectors through continued use due to wear & tear on the platter surface, deterioration of the sensitivity/accuracy of magnetic heads, etc. Fortunately, there is a pool of spare sectors kept by the drive controller to keep these bad sectors hidden from our view. But when the number of physical bad sectors exceeds the spare sectors in the drive's pool, then these bad sectors start to show up in Scandisk and begin to affect the drive's normal functioning.

4. Hard Drives can serve us long when handled properly, such as avoiding SHOCK while it is in use, installing in proper position and orientation, running Scandisk periodically, shutting PC from the Windows SHUTDOWN MENU to allow the drive heads to park to a safe location, etc.

@ruelnov: hope u dont mind na i-post ni ang sketch sa imo place:

grss1982:

No, that's very fine with me. And thanks a lot for posting it. I was actually preparing a sketch of my own and was about to have it scanned for posting here.

Thanks again.

@ ruelnov: no problem!!!

The reason is simple, your system will never boot up if these are indeed the cause/causes. It's either a GO or NO-GO. Secondly: System instability such as random restarting or system hang is mainly caused by faulty capacitors on the mainboard. It is a fact that electrolytic capacitors simply DRY UP (or lose the bulk of its capacitance) with time. And since the majority of mainboards are designed with low cost of production in mind, most capacitors installed don't really last that long and you are indeed fortunate if your mainboard is still alive after 3-5 years! In fact, I have repaired a number of motherboards that have been in use for only 1 year. Unfortunately, you just cannot tell by simply looking at the capacitors if they are bad or still good. Dunay burot nga OK pa ang ESR Reading, duna pod dili burot nga tass na kaayo and ESR Reading. The key actually is to be able to test the ESR of capacitors without ever detaching them from the board. Fortunately, I have that kind of tester and so we are doing it the scientific/professional way. Here's some hard facts about electrolytic capacitors: http://www.freerepublic.com/focus/news/849190/posts However, other board components such as the chipset and all other microcontroller chips do last a very long time if handled with care (usually 10+ years). Lastly, yes I'm reselling reconditioned motherboards and hard disks with warranty.

Found something to validate this story.

@modz: sorry wrong post!!! should have edited the one i made before, instead of posting a quick reply. adain, sorry.

[BhUr9z]

i still have my FUJITSU 20GB na mapawng lang kalit ang iya power causing the OS to hang-up. Pero once makabugnaw ang HDD kay detect nasad balik. pero nig taud2 kay mapawng nasad.. Can u fix this bro? How much man sad kaha imo charge ani? PM me, tanx.

[ruelnov]

To BhUr9z:

Chances are high na maayo nato ning heat problem sa imo HD bai, again I wouldn't say YES or NO unless ma-diagnose jud nako.

But if you want a quick fix which you can do yourself, palit ka Cooling Fan kanang 12V den i-mount mag-atubang sa circuit portion sa likod sa imong HD. This is just a suggestion. Don't carry this out if you're not confident you can do it yourself.

[BhUr9z]

bro, ako na g-gamitan og cooling fan pero it still didnt work. naa jud cooling fan for HD na naa 2 fans naka-mount sa flat metal frame. id like to visit ur shop pero bz man sad gud ko.

Asa dapit imo office sa Victor Village? Naa kay sketch? Like if facing MJ STUDIO, asa inyo dira?
Just in case naa koy kaila nga gusto pa repair..

[grss1982]

@Hot Ice: sir, look at the top of this page, naa kay makit-na na link. thats the map or better yet:

To all those who wanted to have their motherboard or hard disk repaired:

Please come to me only after you have exhausted all means and your unit is still not working, or when you have consulted other technicians/shops and nothing can be done about it.

I don't like you paying me for Quick Fixes such as simple Battery Replacement, CMOS Clearing, replacing faulty Video Card or RAM, re-installing Windows to fix System Hang or Random Restart, replacing Power Supply if CPU Fan doesn't turn, setting Jumper Settings correctly if Hard Disk is not detected, etc.

But I would be most willing to answer if you have technical questions on how to do it yourself for the quick fixes.

HERE'S A VERY RELIABLE FREE SOFTWARE TO TEST ANY TYPE OF MEMORY MODULE:

http://www.memtest.org/

It's called Memtest86+, and I found it very thorough and deep when it comes to testing every adressable bit of memory (EDO/SDRAM/DDR).

It's not enough that Windows can boot then we say that our RAM is OK.

A memory module with failing address bits or intermittent errors can still enable the system to boot into Windows, but then we get lots of surprises such as System Hang, Blue Screen, or Windows behaving erratically. Or a failing memory module can even corrupt a hard disk.

Try it!. Highly recommended.

@mods: oops sorry wrong post, should have PM'ed him instead. again sorry.
