Computer slow a few days after restore (Hardware or Software problem)?

December 23, 2009

I run a windows XP (SP2) desktop, it is about 2 years old.

Intel(R) Core(TM)2 CPU 4400 @ 2.00GHz

So instead of reinstalling my windows, I used repair which just restores the system. After repair, my pc runs very fast, but after using it for a few days, it starts gradually slowing down until it reaches a point where even typing or moving my mouse is laggy. However, this only happens when im multitasking on my windows. If i end all the big processes (antivirus, downloading programs, MSN, etc.), then my computer runs normal again. Another thing i’d like to mention is when im watching a youtube video and I try to open a program, it lags insanely bad for a short amount of time. When I watch a video, even if its loaded, it still lags. I do not use my PC 24/7 but sometimes I leave it on, for downloads. My CPU usage is not necessarily high when my computer is lagging so its probably not a RAM problem. I also have over 50% of free disk space on all local disks.

My PC does not have any viruses, I use Rogers Online Protection, and i am not experiencing any other difficulties except for multitasking slowdown. I’ve tried many things already, I’ve tried to cancel windows updates, stop using anti-virus, I’ve checked all my running processes (searched them on internet) and they were fine, I’ve recorded all the running processes of when my pc was slow and i’ve checked them after repairing my windows. None of these solutions worked. Is this happening to anybody else? Is my PC too old? Could it be a hidden virus? Should I stop downloading and see what happens? Is this a case of software or hardware?

I don’t want to use my computer without being able to download and use the internet at the same time, or cancel antivirus. And I don’t want to repair it every few weeks/days. I am not a pro at these kind of things, so plzz help!

How do I speed up my notebook computer?

December 12, 2009

I own an ASUS A8Js laptop
Intel Core 2 Duo T2700 2.00 Ghz
RAM 2GB
nVidia GeForce Go 7700

I would like to speed up my computer without a system reformat, I am running in Windows XP Professional SP2 and am NOT looking to upgrade to Vista. How can I improve the performance and speed of my notebook computer?

Installed new hardware and now windows won’t start.?

My brother built a new computer based around a new processor and motherboard, (intel Quad-core Q6600 and Asus P5E), along with a new case so it would be compatible(Antec 900). After transferring over these new parts along with the necessary older parts the computer works fine except for one problem. Everything powers on, the computer gets past BIOS and then goes to boot windows but instead he gets:

"Windows Error Recovery"
Windows failed to start. A recent hardware or software change might be the cause.

If windows files have been damaged or configured incorrectly start up repair can help diagnose and fix the problem. if power was interrupted during startup choose start windows normally.

Launch startup repair(reccomended)
Start windows normally

Whenever he starts windows normally he gets the blue screen of death and an instant restart. If he launches repair it goes to a loading bar that completes in about 5 seconds then just sits at 100% and does nothing.
P.S.
We do not have a copy of windows vista, it came installed on the computer and we never recieved an actual copy.

He cannot get to the actual desktop to do any of that from, windows will not launch.

What is wrong with my PC? **PC expert needed**?

November 26, 2009

My PC has recently sprung a new problem on me that I can’t solve. I am by no means a noob but this has got me baffled!

I am using Windows Vista with Intel Core 2 Quad CPU

The problem is that my PC will turn it’s self off for no apparent reason… I can be doing my normal work at my PC and it just goes off, no "Windows is Shutting Down" message no logging off message, nothing, just turns it’s self off.

If I try to turn it back on it wont boot up, I need to wait a few minutes before I can turn it back on (this suggests to me that my PC turned off as a precaution as my processor was over heating but I don’t know to be honest)

It started to happen more often so I ran Windows task manager to see what could be pushing my CPU so hard… nothing obvious there but all 4 cores were running at 100% when my PC turned it’s self off again so I’m pretty sure my PC is turning off because of it but I don’t know what is causing my CPU to run at 100%

I’m running a lot of programs at the same time I must admit but this was never a problem for my PC (at most it would use 80% total CPU for the same amount of open applications and that really is at the very most!)

Needless to say I have ran a virus scan and nothing come up (NOD32 anti virus)

I have also used CCleaner… Run Reg Cure and Registry Cleaner, Tune Up Utilities 2009 and Malwarebytes’ Anti-Malware… none of them helped even a small bit.

Stupidly I deleted my restore point that was created before this problem started so thats not an option.

I appreciate any help as always.
