Sudden (significant)drop in perfomace

jirakst · Jun 13, 2014

Hello,

I have buy a PC (Sun Microsystems Ultra 20: AMD Operton 1218, 8GB RAM, nVidia Quadro FX3500 512MB, 160GB SATA) and everything was running swiftly until I picked it up and switched it on in my friend´s flat (actually, I was doing it for his father but I doesn´t matter). After I turned it on it was incredible slow, it takes a lot of time to run any application or open a folder. Perfomace is nearly comparable now to his old computer with AMD Sempron and 768MB RAM!
Please would anybody know what could cause this drop in perfomace? Note, that everything seems to be working property otherwise and it was runing fast before.
Thanks in advance.

Sounds like hard drive issues... Get yo data backed up quick, then run Check Disk

jirakst · Jun 13, 2014

Yes, it is what seems to me, but I have checked up the SMART and everything was looking good.

Additionaly, I forgot to tell I was copying some data to the HDD with total amont about 27GB and it taken app. 5 hours with a ave. speed 3MB/s!

How full are your drives? Hav u tried a System Cleanup?

jirakst · Jun 13, 2014

There is complete new installed system (Win7) and it worked pretty fine before I replaced it to my friend´s appartment. It is quite strange because I haven´t thud it anywhere and the readings head of the disk are in parking position while disk is turned off, so the disk would not work at all if damaged.

Hav u run a full virus check and malware scan? What software did u use?

Download Avast/Bitdefender as well as Malwarebytes and run full scans. Do the same for CCleaner as well.

Actually, I have installed cracked ESET Smart Security 5. It required reboot in safe mode and run fix app to path(crack) the antivirus. Since ESET haven't find anything, could be the crack a virus which cause terrifying slowdown of the system? I don't have access to the computer now, the friend of mine is at university this weekend and his parents are enjoying the holiday. But I installed it (eset) at their's old notebook (originally suffer from broken keyboard and touchpad) which doesn't show so huge drop in performance. I may try installed it to my MacBook via Bootcamp, but not sure if the potential virus will cause observable slowdown here(will let you know).
Thank you for your guidance.

Firstly, you'll get no respect here for using cracked software.

Secondly, it is possible that your massive slowdown is simply a result of yo antivirus settings if everything seemed fine before you installed it? A recent antivirus suite will be designed to run on a system with an up to date spec - if yo HD is SATA 1, it won't handle it very well

Hello,

I have the computer at home now. The HDD is SATA-II and I've checked all possible about the disk (SMART,benchmark, error scan, aam, ...), everything is OK. What seems to me very odd is the computer runs perfectly sometimes. It was running normally when it was in my apartment and was running slow when I connected it in the apartment of my friend's parents yesterday and was running slow today until I arrived a couple of hours before. Now I have it back again, restarted it serval times and still running perfectly. I see no another try then re-install operating system, what about you?

snowctrl · Jun 15, 2014

It shouldn't come t that - carry on using it, and next time it goes slow, open up Task Manager and see where t CPU is being used. Also watch yo drive lights for excessive drive use.

Finally, install a program that monitors yo CPU n GPU temps so u can see if heat is t cause

jirakst · Jun 15, 2014

OK, thank you for your advise and quick respond. I'll let you know how the situation develops.

jirakst · Jun 15, 2014

A couple hours of using and still running smoothly up to now (I've also ran some performance benchmark to load it a bit). I've google up some people have experienced drastically slowdown after downloaded and installed Windows's updates. The PC is not connected to the internet in my apartment due to provider rules. May this be what happened?

jirakst · Jun 16, 2014

Black news indeed. Due to my final exams tomorrow I decided to reinstall the computer this morning. So I put in a DVD, formatted disk and when I was trying to pick up the disk for installing, the message appeared says something like "The program could not create new system partition or find existing partition. For further details see program protocol in files." What the heck? It was working before. Where can I find the protocol?

jirakst · Jun 16, 2014

It's working now. I forgot my flash disk in the USB during installation.

Windows reinstalled, no problem has occurred up to now.

snowctrl · Jun 16, 2014

Well done.... can I suggest in future you DON'T try a full re-install the day before something critical like an exam....?

jirakst · Jun 16, 2014

Actually, I am having a work interview also (quite busy day)

Otherwise, computer seems to work fine and I can only thank you, snowctrl, for your guidance, advises and time. Not sure entirely if I would be able to finish it myself. Thank you!

snowctrl · Jun 16, 2014

No worries - best of luck with the interview, etc
