laptop build in graphic mismatch

chan1314 — Sat, 10 Jan 2009 01:42:05 +0800

an acer 4520 lappy, which has build in graphic nvidia 7000m, in the windows shown 512MB, but in the bios max can go up to 256 only. i tried update bios, and used the latest or any driver. but still get blue screen when dota. how can i solve this problem? windows xp. sorry i didnt record the blue screen code. but i think tat is windows driver recognize graphic ram has 512 but actually accessible only 256, so the memory access problem cause the bluescreen. i will update immediately if i play dota.

Ms c++ stack stuck..

i need to use stack to do some simple calculation +-*/ wif () ,
but i cannot get the answer , my result always 0.

my header is

QUOTE

#define SIZE 10

typedef int StackType;

struct Stack{
StackType Item[SIZE];
int top;
};

void InitializeStack(Stack &);
int EmptyStack(Stack);
int FullStack(Stack);
void Push(StackType, Stack &);
void Pop(Stack &, StackType &);

implementation is

QUOTE

#include <iostream.h>
#include "Stack.h"

void InitializeStack(Stack &S){
S.top=0;
}

int EmptyStack(Stack S){
return (S.top==0);
}

int FullStack(Stack S){
return (S.top==SIZE);
}

void Push(StackType x, Stack &S){
if (FullStack(S)) {
cout<<"Error : Stack Fulled"<<endl;
}else {
S.Item[S.top]=x;
S.top++;
}
}

void Pop(Stack &S, StackType &x){
if (EmptyStack(S)){
cout<<"Error : Stack Empty!"<<endl;
}else {
S.top--;
x=S.Item[S.top];
}
}

and my code is

QUOTE

#include <iostream.h>
#include "Stack.h"

main(){
Stack S;
StackType x , y;
int result=0;

InitializeStack(S);

cout<<"Enter Number : ";
cin>>y;

for (int i=0; i<'\n'; i++)
Push(y,S);

while (!EmptyStack(S)){
Pop(S,x);
switch (x){
case '+': result = result+x;
break;
case '-': result = result-x;
break;
case '*': result = result*x;
break;
case '/': result = result/x;
}

if(x!=0){

if (x=='('){
Push(x,S);

}

else if( x==')' ){
if(!EmptyStack(S)){
Pop(S,x);

switch (x){
case '+': result = result+x;
break;
case '-': result = result-x;
break;
case '*': result = result*x;
break;
case '/': result = result/x;
}

}
}

}

cout<<"Result : ";
cout<<result<<endl;

return 0;

which part is wrong ?
reference part ?
or the main code ?

HDD detected wrongly in bios

chan1314 — Thu, 26 Oct 2006 15:58:23 +0800

i have 2 seagate IDE40GB hdd , i use as my primary master and secodary.

start from yesterday , my secondary HDD unable to access in windows , so i found tat windows set it to PIO mode.and my drive become unallocate. i allocated back to my drive , it only allocated 5GB , the rest dissapear.

after tat i restart look at bios , i found tat my problem's hdd become alot unknown code in vendor detail , unknown size, another same model hdd detected as usual.

i think not the bios problem , since my mobo LAN faulthy last 2 day, my hdd got problem.

any problem will make the hdd like tat ? virus ? or mobo problem ? or the hdd problem ?
the hdd used just few hundred hours only.

network cant use

chan1314 — Wed, 25 Oct 2006 01:41:18 +0800

while just now raining , suddently saw spark and sound from my modem , after tat my mobo asus k8n build in LAN cant use.
it is always connected even i unplug , and no receive packets. my router doesn't show connected , but LED on router shown got data transmiting from my pc.
i reset bios , format my pc , and i tested my modem , router , all function properly , mean tat my mobo ethernet was going crazy.

i plug a new NIC into my PCI slot , but in windows its shown exclaimination sign , said tat not enough free resourses to let the device use.
1stly i thought is IRQ conflict , but i change to other PCI slot and test other NIC card , it gave me same result.

is tat my controller burned ? now only network adapter cant use neither build in or PCI.
my USB and sound function properly.

so other than change new mobo , any other solution ?

if i buy a USB to RJ45 convertor , izzit will give me same result like the NIC card ?
i afraid if like tat , wasted my money to buy it.
my house has wireless connection , so is tat wireless and local area network using same resources or via same controller ?

infineon CE-5

chan1314 — Wed, 06 Sep 2006 14:43:48 +0800

wat is the problem ?

i using infineon ce-5 ecc 1GB , but i face a problem
my clock cannot higher than 225 and the timing cannot lower than 3-3-3-8.
i tried to set higher voltage but when playing game is more lagging and the timing or clock is same.

even i tried set 2.5-4-4-8 @200 also cannot boot . since this ram look like default voltage so i din add any voltage.

is this ram is "impotent" ? or need to burn it to let it become clockable ?

why below my avatar show warm 0%?

chan1314 — Mon, 28 Aug 2006 01:54:26 +0800

i read from FAQ , warm 0% mean NOT been warned. but only me got tat bar ?
