MY PC has issues what it is doing it is blue screening, it all started after I upgraded the video card and memory. I took PC back to the shop where it was build and they couldn?t find anything wrong with it, so last night I turned it on and same thing it blue screened last night and this morning, the only thing I noticed is on error message is different last night it was IRQL not less than equal, and this morning it was memory dump. Another person at work said it might be a blue screen virus but wouldn?t the technician find it if he ran a virus scans? The person who worked on it told me he did a memory test and all functioned fine and un-installed drivers for video card and installed latest drivers for it. What else would be the problem? Could it be a blue screen virus or something else?
Here are the specs for PC.

VC/ EVGA 9800 GT 512 Drivers 8.15.0011.8585

First, run Memtest86 to test the RAM, goodgle "Memtest86" and download either the bootable floppy, iso, whatever suits you. Boot your PC to that and test the RAM, let it run for a bit. Does it Blue screen right away?

sometimes it bluescreens right away and sometimes it takes a few minutes 2-5 minutes.

OK I did the memtest86 and there was no failures. What would be the next step?

 

[ch33zw1z]

Let that shit run for a while, 1 pass isn't always enough. If passes 4-5 ok, then I'd say move on. What kind of PSU are you using? Very important that the VGA is getting enough juice..

 

[will083031]

Ok will do the power supply in box is an okia 500W.

 

[ch33zw1z]

I've never heard of Okia, chances are if you check out the tag on the side, the 12V won't have more than 25Amps on it. I would not trust it IIWY.

edit, please post the complete system specs.

Hard drive WD 320gb (3200AAKS) memory DDR2 6400. On power supply should I look into getting a other one?

You need to list more specifics for the components, like model numbers for the RAM, CPU, and also if you're overclocking or not. Head over to the PSU section of the forums and ask what PSU you should get, I can't keep up with everything...so that forum is the place for a good recommendation. When you post there, reference this thread.

sounds like a memory module going bad. Have you tried taking all the memory modules out, and putting one memory module in at a time to see if the problem still happens?
