Slow boot up, sometimes program missing, HDD problem?

March 5, 2012 at 16:07:21
Specs: Windows 7
I have experiencing a slow boot up after a lightning storm strikes, and some of my programs are not functioning properly. Issue that i faced after boot up:

1. Some drivers could not be detected properly, sometimes it works fine
2. Some programs working properly, and suddenly went missing
3. Some programs could not run at all, another boot up may solve the problem occasionally.
4. Sometimes BSOD may appear in the progress of booting up and sometimes it works fine.

It could be some other issue that i had not found, this is the current problem. Is this because of my HDD problem? I had ran a disk check and also using HDD scan, and it show no bad sectors. HDDscan shows a few slow sectors. Does the slow sectors causing all these? Or is it some other matter that causing these?

I would suspect bad RAM. Download Memtest and let it run overnight.

I've never heard of slow sectors, if the sectors are having trouble being read, then they are bad, period.

@THX1138

Thanks for the alternative solution, i'm currently running memtest now. Will report here after it's done.

In HDD, not all sectors are read/write at the same amount of time, some might be slower, HDDscan is able to detect how much time it need read/write into the particular sector as well as bad sectors. So in this case, since there's no bad sector detected, i'm just wondering whether is it the slow sectors are causing the problem.

I've done a memory test using memtest86+ v4.20. Passes 4time without any errors for 8hours+. So i will make an assumption that my memory is working perfectly (If the testing is accurate). I also tried removing & changing memory stick and the problem is still there.

Oh, and I forgot to mentioned that I had already formatted my HDD a few times, and made a clean installation of windows 7, and the problem still retains.

Before jumping into conclusion, I hope more experts out here can provide more information on this. Based on a few testing, discussions and articles i found, my suspect here is still my HDD problem, can anyone argue this point?

Well, suspect doesn't mean guarantee, don't really want to waste money buying a new HDD just to test it out without any satisfaction answer. =/

It possibly could be hard drive (maybe in the electronics), but It is probably a power issue since your power supply would have taken the worst of the hit from any power surge. Check in your BIOS set up and read your Voltages, all of them should be within 5% of their nominal specs (3.3V, 5V, & 12V all should be +- 5%), if not then there is where your intermittent issues may be coming from.

You have to be a little bit crazy to keep you from going insane.

Hi Fingers, thanks for the quick reply.

I had checked my hardware components power consumption, all voltages are within the nominal range. For your information, previously i was using 1000W which is already dead due to the lightning strike, and I had downgraded to 850W which I think is more than enough to support my current specification. Maybe i will just list down my components in case anyone here needs to know it.

CPU: i7-2600K
MOBO: Sabertooth P67
RAM: Corsair 8gb (C9) Dual channel x 2
PSU: Corsair AX850
GPU: GTX560 Ti Twin Frozr
HDD: WD 1TB x 2
Casing: Cooler Master HAFX

If the lightning strike fried the original power supply then some of the extreme surge may have leaked through to other components and there may be other damage. This may not be visible, but might, be so take a strong light and do a thorough visual inspection of the motherboard for components that show some burnt color.

I am thinking that a lighting strike, that was enough to kill the PS, may have done other damage. You think it is the medium used for the OS, than try another meduim.

@Fingers @larryf215
Yeah, that's what I suspect also, if the strike can kill my PS, it might leak to some other components also. I think I have no choice but just to swap all the components individually to test it out. Hope it's not my board that is damaged. Will report here again once I had finish diagnosing it.
