When running antivirus and spyware full scans the system cache will max out where the program will stop and the system becomes lagged where a restart is needed. No malware was detected by scans in the virus forum so I was led to post here again.

Here are pictures of my current processes, performance, and startups. In performance you'll notice that my system cache is currently around 1358000 since I'm not running any scans, but during scans the system cache peaks around 2755000 then a reboot is required.

Computer details:
Gateway 838GM Desktop
Operating System: Windows XP Media Pro (5.1, Build 2600) Service Pack 3
Motherboard: Augsburg Intel D915GAG, 800MHz bus, GMA900 graphics, 196MB ram
Processor: (2)Intel P4 630HT, 3GHz cpu, 800MHz FSB, 2MB L2 cache
Hard Drive: Seagate Barracuda 200GB, 7200RPM, SATA, 8MB buffer
Physical Memory: Crucial 4GB, DDR400, PC3200, 128M bit x 64
Virtual Memory: 2GB, available 1.95GB
Page File: 4.6GB
Power Supply: Antec 430W
Antivirus: Avast 4.8.1368(had problems with 5.0 so I uninstalled)
Spyware: Spyware Terminator 2.6.6.196(included Clam AV disabled)

I would also like to add....

His computer is free of malware. He does have corrupt system files. He has been unable to run sfc /scannow as he does not have an install CD. I tried to alter his registry to point sfc to an i386 folder we placed at the root of the drive but it unfortunately failed and still prompts for the install disc.

Thanks for the help,

Yeah, unfortunately, it rarely works (from my experience).
Since "sfc" asks for the CD, then surely we have some system files issues.

I suggest borrowing CD from a friend/family member.

Ninja thanks for posting the link to the old thread since I forgot to.

Delta, no I run the scans separately.

I have no one to borrow a xp cd from. Can I run sfc then write down every file it requests the cd for, then exit sfc at the end, and then copy each of those files from the c/xpsp3/i386 folder and paste it into the c/windows/i386 folder to replace the files manually?

EDIT: I deleted the java update startup entry too btw. Saw it after I posted the startup picture.

You can try. You won't hurt anything.

IMHO, everyone should have Windows CD, because it's needed sooner, or later.

FWIW: I've had the same experiences/perspective as Broni on this i386 thing. I spent a couple of hours trying to get it to work and I usually don't suggest it.

Borrow/burn/buy a CD with the same version is the best solution, IMO.

What is everyone's opinion about his problem with the system cache maxing out requiring a restart when he is running a scan? This is a 64 bit system with 4gb of Ram if I read the specs correctly. That shouldn't be happening right?

What exactly do we mean here by "system cache maxing out"?

Well...I guess that I don't think that a problem has been well defined...there's been a lot of verbiage...including some about corrupt files.

There's only one way to cure damaged files...you replace them.

If the OP doesn't have the capability to replace possibly damaged system files...he needs to be directed as to how to obtain that capability. And then he has to act on such.

No matter how much I might want to run sfc /scannow or do a repair install of XP...it ain't gonna happen without an XP CD or some alternative tool.

I must be missing something :thumbsup:.

A system running 32-bit XP with 4GB of RAM...I find it hard to believe that said system has problems relating to memory utilization, since it has minimal dependence on the pagefile.

If it does...then I would think that testing the RAM would be in order...but I haven't seen anything posted here to make me believe that there is a RAM problem of any sort.

No BSODS...no Event Viewer errors relating to such...I've not seen anything but Task Manager screens which don't indicate a problem, IMO.

The system has already been given the "all clear" from a malware possibility...I do not get it. A system with 4GB of RAM...even if the system cache were totally consumed...then turns to the pagefile. The result might be a slowing, but it would not be a crash, a freeze.

I'm out of my league on this one, sorry :flowers:.

Louis
