long story short, my 2730p has been giving me numerous problems and it seems like i will have to reinstall windows as many dlls have gone missing/broken (and the damn thing is barely usable now)... before doing so, i'd like to make sure that everything is functioning fine on the hardware level.

what are some good tests for checking the condition of components?


unfortunately, the info that i have on testing computers is rather dated (and iffy).

voltage:
no clue.
is there a program that can check the condition of a psu?

hdd:
seagate test (in past experience, it gave a good status even when an hdd was just about to die)
hp hard disk test (likewise...)
crystaldisk (likewise)

ram/cpu:
memtest86 (this program actually does work, although i doubt that i have a ram problem)
prime95 (i've never been able to capture a snapshot of instability with either this or the following two programs)
superpi
occt


also, is there a place where a 2730p system recovery iso can be downloaded?

many thanks!

Well, the problem with checking the power supply is that you can't just poke a voltmeter at it and call it a day. You have to apply some kind of load to it and measure the voltage across the load. Especially the case with batteries (batteries may output their nominal voltage if you just poke the leads, even though they're basically dead). Oh and yeah, you can't use software to check it. If you need to check the power supply/battery, it's a hardware thing.

In any case, I would start with replacing the hard drive first.

hi, thanks for the info!

>replace hdd
aw damn, i was hoping i wouldn't have to do that... i only just replaced the hdd about a year ago as the last one completely died (what happened to that hdd is, the bootup got slower and slower and one day it just hung on the os loading screen ... after about half an hour, i rebooted and then bios says it's no longer a valid hdd).

the current model is a toshiba mk1633gsg

would a solid state drive would be more reliable/ more resistant to power problems?


i'll be running memtest, prime95 and the seagate test soon.

in the meantime, do these problems seem characteristic of any specific type of failure?


TOUCHSTICK MOUSE RIGHT/LEFT CLICK PROBLEMS
booted into a different os (linuxmint ), found the same touchstick 'mouse' problems (!!!) or at least a similar one, where right click stopped working ... i think that would indicate a hardware problem

back in vista...
left click stopped working for about 10 hours ... had to click right click before left click would work ... typing quickly would randomly elicit a right click effect ... this problem persisted through multiple restarts ... then, as mysteriously as this problem appeared, it went away, without restarting or anything. weird.

due to the random nature of this problem, i wonder if perhaps i have a piece of conductive dust in the system or something ... i THINK the mouse problems started after i tried blowing into the vent of the heatsink to clear out any built up dust ... that did dislodge some 1cm long whitish fibers (probably nylon or something) that i then had to tweeze out of the intake vent ... there's probably a lot more back there but i'm having a devil of a time trying to access the heatsink (there seems to be a hidden screw keeping the panel in place)

if this problem had not persisted into a different os, i would have already reinstalled vista. as it is, i don't feel very secure doing this ...

another touchstick mouse problem that occurs sporadically is that clicking left click will elicit the behavior of clicking right click ... and clicking the right click elicits no response. furthermore, the right click menu will sometimes pop up by itself when typing. clicking with a usb mouse seems to reset these issues.


TESTS
ran windows memory diagnostic, passed with no errors

ran vista disk check ... had no effect ... found bitmap errors, crosslinked files, orphaned files ... can produce logs if desired

ran sfc /scannow ... found numerous missing and broken dlls ... more info further down

the operating temps are not the highest they've ever been ... between 37-40 degrees celcius

ac adapter voltage (checked with multimeter) is perfectly stable and within parameters ...


LAGGING
every 3-5s and every action elicits a random laggyness of between 5 and 30 seconds ... chkdsk didn't fix the lag problem. ... there are random pauses during playback of a local 5mb mp4 file in vlc ... clicking _anything_, opening a webpage, switching tabs, even hovering over things, etc will elicit the spinning circle 'busy' animation ... with just two tabs and nothing else open other than notepad++(!) ... there is lag when selecting text and typing into google ... everything causes lag other than moving the mouse back and forth

amazingly, if i wait about 20 seconds before logging in, the longer i wait, the longer it will take for the 'enter password' screen to appear ... and getting to the desktop can take anywhere between 30 seconds to 5 minutes to never (as in, the screen goes black and nothing happens) ...

if i leave the pc on, eventually the lag will get worse and affect more things, including there being tremendous lag before turning the screen back on after returning from idleness ... if enough time has passed, the screen never turns back on and the only option is to reset.

one time, saving a txt file as the lagging was getting worse turned the contents of the file into junk.


BSOD

just got one recently, after attempting to open a txt file in notepad++ caused that program to crash.
unfortunately, it disappeared before i could write anything down ... can't seem to find the bsod in the event viewer, though i'm not sure what i should be looking for ...

windows\ minidump\ is empty ... there is no memory.dmp ...

HOW IT ALL STARTED
i have no idea.

all of these problems are coincidental with installing a new version of java a few days ago ... based on the non os specific nature of some of these problems, i think that is just a red herring ... i used system restore to roll back to a much earlier date and that didn't fix anything ...

a few days later, i got a windows update error: "WindowsUpdate_8E5E0147"

and that's when i ran sfc, which fixed nothing ... multiple dlls are still missing or broken ...

PS: possibly unrelated, i found a small, whitish dust mite crawling on the top of the screen after placing the laptop down on an outside table ... this occured long after these problems started but i do tend to use this laptop outside quite a bit ... opening the main access panel at the bottom of the laptop reveals no obvious infestation or any bug carcasses, although only a small bit of the mobo is revealed ...

PSS: long before any of this happened, i used to run into similar problems after running a java program called jdownloader; basically, the pc would start getting more and more glitchy ('cannot locate hard disk' errors when the hdd is perfectly fine) and laggy until i restart ... but these problems would only happen after i'd start that program and would never occur otherwise. i could literally have the pc on for months and not run into a single problem ... but after starting jdownloader for 30 minutes, BAM.

these problems are coincidental with downloading a java update. i'm not sure what the connection is but it seemed to trip something off...
