Hello. I need help please. My computer has lately been freezing up on me. The screen was freezing and ctrl alt delet did not work. had to push restart button. Now when i go to turn on my computer the power light comes on and the hard drive spins but on my screen nothing comes up. Its a custom built computer intel duo chip with 2 gig ram and 2 x nvidea geforce 9800 gt's in sli format. at first i thought it was overheating as it would work for a while before freezing up now i am wondering if it is somthing else. Any help please.

When does it freeze?
Is crtl+alt+del (Task Manager) disabled permanently? or temporarily disabled at the time of freezing?

So you mean its plain black?

Hi limmerman.

How old is the pc? Fairly new by the sounds of it. What is the power supply rated? (wattage?) That would be my 1st suspect. Overheating as well. Where is the box physically located? You may have enough fans, but if the box can't get airflow, it"ll overheat. And are the fans set for airflow? If the fans are all pointed in or out, there is zero flow. Check the PS and mobo for bulging caps (unplug the pc 1st!)

Good Luck and let us know what you find.

Do you get "nothing" on the screen - or does the BIOS POST stuff show up? If you get some display, then I'd suggest some testing with a bootable CD/DVD. If you get absolutely nothing, then it's likely to be a video problem (check the connections and see if you can borrow a video card to try in it's place).

When the problem started and it started freezing It could happen anytime. from 1 min in to 2hrs or more. When it froze nothing worked ctrl + alt + delete did not work if a timer was on the screen it froze all stop like sombody pushed a pause button. now when i power up i get nothing. plain black screen. What i used to get was the aseus screen which i think is my motherboard name. To usasma iyes i get "nothing" on the screen. No bios stuff or anything. When i turn it on the front "temp gauge" lights up and shows temp usally runs between 77-85 and it beeps 5 times. thats all. I will try another video card if i can find one to try. am hoping it will be an easy fix. Thank you for all your responses and any more responses with ideas will be helpful.

I also had that experience and problem just recently and mines could even hang like 30mins or 5 mins but now,i did a fresh reformatt and the problem vanished
But if you insert a disk into your drive,does it hang? as it did to me

5 beeps = not good. Dbbl check and make sure
Bios beep codes

Ok yes it is 5 beeps problem is im not sure which bios my computer uses if it is the Phoenix BIOS It beeps twice fast then 3 single beeps. Question is how do i know which bios my computer uses and if it is the phoenix BIOS and means my memory is bad can i fix the problem by removing the ram sticks and trying them one at a time (my comp uses 4 x 512Megs) ? I cant use BIOS agent or any other program as my computer will not boot up.

What is the make and model number of the motherboard?

Let us know the make and model of your PC (or the motherboard if it's custom built).

Has anything happened to the PC recently? Being moved/bumped, power surges or outages, kids with peanut butter sandwiches?

Have you checked the cabling between the monitor and the PC (including the connectors) to ensure that there's nothing wrong there? Have you tried another monitor to ensure that it's not the monitor that's gone bad (unlikely, but possible)?

It is not the monitor.The make of the motherboard is asus. not sure about the model. I am responding to the posts when i am at work.Will check.
